Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, the purchasing information of purchased clothes is generally obtained from an e-commerce website, and then the fashion trend analysis is performed based on the purchasing information, however, in addition to the purchasing data of purchased clothes, the purchasing information obtained from the e-commerce website generally has a large amount of exchange data and/or return data, and the existence of the exchange data and/or the return data may cause errors in the analysis result when the fashion trend analysis of clothes is performed, so that the analysis result is not accurate enough.
In view of the above, embodiments of the present invention provide a method and an apparatus for analyzing a product popularity trend, an electronic device, and a storage medium, so as to obtain an attribute value of each visual attribute of a target product in each target product image by acquiring a pedestrian image photographed at an entrance/exit of a business center, extracting a target product image from each pedestrian image, identifying each target product image, and finally determining a popularity trend of the target product based on the attribute value of each visual attribute of the target product in each target product image. Therefore, the method can avoid using a data set containing the exchange data and/or the return data to perform the popular trend analysis, and improve the accuracy of the popular trend analysis of the product.
Next, a method for analyzing a product popularity trend according to an embodiment of the present invention is described first, and as shown in fig. 1, is a flowchart of a first implementation manner of the method for analyzing a product popularity trend according to an embodiment of the present invention, where the method may include:
and S110, acquiring an image set of pedestrian images acquired by the video monitoring equipment.
In some examples, the video monitoring device may be installed at an entrance or other busy areas of various malls in a city, and then the video monitoring device may collect images of pedestrians, so that the images of pedestrians collected by the video monitoring device may be acquired, thereby forming an image set including a plurality of images of pedestrians.
In some examples, in the image set, pedestrians in at least two pedestrian images in the image set are different, and the ratio of the number of pedestrian images with different pedestrians is within a preset ratio range, and the pedestrian images in the image set include the target product image;
for example, the image set may include 3 images of the pedestrian a, 4 images of the pedestrian B, and 5 images of the pedestrian C, where a ratio of the number of images of the pedestrian a to the number of images of the pedestrian B is within a preset ratio range, a ratio of the number of images of the pedestrian a to the number of images of the pedestrian C is within a preset ratio range, and a ratio of the number of images of the pedestrian C to the number of images of the pedestrian B is within a preset ratio range. In still other examples, the smaller the preset ratio range is set, the closer the number of pedestrian images of the respective pedestrians.
In still other examples, the preset ratio range may be a ratio range that is preset empirically. For example, the range of the amount of the organic compound is 0.8 to 1.2, or 0.9 to 1.1.
In some examples, the target product may be a product that analyzes a popularity trend using the method for analyzing a popularity trend of a product according to an embodiment of the present invention, and the target product may include: jackets, pants, jackets, watches, glasses, hats, masks, and the like.
And S120, extracting a target product image from each pedestrian image.
After an image set containing a plurality of pedestrian images is acquired, a target product image may be extracted from each pedestrian image.
In some examples, when the popularity trend of a plurality of products is analyzed, and the target product is a plurality of products, a plurality of target product images can be respectively extracted for each target product, wherein the target product images are respectively in a plurality of pedestrian images.
S130, identifying each target product image to obtain the attribute value of each visual attribute of the target product in each target product image.
And S140, determining the popularity trend of the target product based on the attribute values of the visual attributes of the target product in each target product image.
In some examples, after obtaining the target product image, in order to determine the popularity trend of the target product, each target product image may be identified first, so as to identify the attribute value of the visual attribute of the target product in the target product image.
In some examples, the visual attributes may include: style, color, brand, etc.
In still other examples, each target product image may be input into a pre-trained recognition model for analysis, so that the attribute values of the visual attributes of the target product in each target product image may be obtained. The recognition model obtained by pre-training can be obtained by training by adopting a product image sample labeled with visual attributes.
After the attribute values of the visual attributes of the target product in each target product image are obtained, the popularity trend of the target product can be determined based on the attribute values of the visual attributes of the target product in each target product image.
In some examples, the popularity trend of the target product may refer to the most popular product, which may refer to attributes of the product, e.g., style, color.
In still other examples, the popularity trend of the target product may also refer to some products that are relatively popular.
Therefore, when determining the popularity trend of the target product based on the attribute values of the visual attributes of the target product in each target product image, the target product corresponding to the visual attribute with the largest attribute value may be determined as the most popular product based on the attribute values of the visual attributes, and/or the target product corresponding to the visual attribute with the attribute value ranking before the preset number of digits may be determined as the popular product based on the ranking of the attribute values of the visual attributes from large to small.
The preset digit may be a digit preset manually, for example, the preset digit may be 3 bits, or may be 10 bits, and the like. When the preset digit is 3 digits, the target product corresponding to the visual attribute with the attribute value sorted to the first 3 digits is determined to be a popular product based on the sorting of the attribute values of the visual attributes from large to small.
According to the method for analyzing the product popularity trend provided by the embodiment of the invention, when the popularity trend of the target product is determined, an image set of pedestrian images acquired by monitoring equipment can be firstly acquired, then the target product image is extracted from each pedestrian image, each target product image is identified, the attribute value of each visual attribute of the target product in each target product image is acquired, and finally, the popularity trend of the target product is determined based on the attribute value of each visual attribute of the target product in each target product image. Because the pedestrians in at least two pedestrian images in the image set are different and the ratio of the number of the pedestrian images with different pedestrians is within the preset ratio range, the pedestrians in the different pedestrian images in the image set are not completely repeated, and because the products in the pedestrian images are worn on the pedestrians and can represent the wearing tendency of the pedestrians, the popular tendency of the target products is analyzed based on the target products in the pedestrian images, the popular tendency analysis by using a data set containing the goods change data and/or the goods return data can be avoided, and the accuracy of the popular tendency analysis of the products is improved.
On the basis of the method for analyzing the product popularity trend shown in fig. 1, an embodiment of the present invention further provides a possible implementation manner, as shown in fig. 2, which is a flowchart of a second implementation manner of the method for analyzing the product popularity trend according to the embodiment of the present invention, where the method may include:
s210, acquiring a video acquired by the video monitoring equipment by adopting a multi-target tracking algorithm.
And each video frame in the video is marked with the position of the target frame and the target label.
S220, extracting a video frame from the video, and acquiring a pedestrian image containing a pedestrian from the extracted video frame based on the target label and the position of the target frame of the extracted video frame.
In some examples, the video monitoring device may capture images of pedestrians and may also capture video. In order to obtain a plurality of target product images from one pedestrian image, the video monitoring device can adopt a multi-target tracking algorithm to acquire a video. Therefore, videos acquired by the video monitoring equipment by adopting the multi-target tracking algorithm can be acquired.
When the multi-target tracking algorithm is adopted to collect videos, the video monitoring equipment can respectively establish labels for people and/or objects appearing in the monitored area and track the motion tracks of the people and/or the objects in the monitored area, so that videos marked with the positions of the target frames and the target labels can be formed. In some examples, the object tag may indicate that the object in the object box is a person or object.
After the video shot by the video monitoring device is obtained, video frames can be extracted from the video.
In some examples, the video frames may be extracted randomly from the video, or the video frames may be extracted sequentially in the order of the video frames in the video.
After the video frame is extracted, a pedestrian image including a pedestrian may be acquired from the extracted video frame based on the target label and the position of the target frame of the extracted video frame.
In some examples, since the extracted video frame has the target tags and the positions of the target frames, an image having the same size as the target frames may be acquired from the extracted video frame, and since each target frame has a corresponding target tag, an image in which the target tag is a person may be determined based on the target tags, so that an image of a pedestrian including a pedestrian may be acquired.
In still other examples, after sequentially extracting the video frames in the video, the video sequence may be obtained according to the order of the video frames in the video.
In still other examples, the trajectory analysis may be performed on the video to obtain the trajectory of each pedestrian in the video. And then extracting video sequences corresponding to different pedestrians from the video sequences based on the track of each pedestrian in the video.
For example, the position of each pedestrian in each video frame in the video sequence is determined based on the trajectory of each pedestrian in the video. Then, based on the position of each pedestrian in each video frame, the image containing the pedestrian is extracted from each video frame, and then based on the image of the pedestrian corresponding to each video frame, the video sequence corresponding to the pedestrian can be obtained.
And S230, extracting a target product image from each pedestrian image.
S240, identifying each target product image to obtain the attribute value of each visual attribute of the target product in each target product image.
And S250, determining the popularity trend of the target product based on the attribute values of the visual attributes of the target product in each target product image.
It is understood that steps S230 to S250 in the embodiment of the present invention are similar to or the same as steps S120 to S140 in the first implementation manner of the embodiment of the present invention, and are not described again here.
In some examples, the image set may include at least two pedestrian images of different pedestrians, the pedestrian image of each pedestrian in the image set may be the same, and the pedestrian image of each pedestrian may be 1 or more, for which, on the basis of the method for analyzing the product popularity trend shown in fig. 2, the embodiment of the present invention further provides a possible implementation manner, as shown in fig. 3, which is a flowchart of a third implementation manner of the method for analyzing the product popularity trend according to the embodiment of the present invention, the method may include:
and S310, acquiring a video acquired by the video monitoring equipment by adopting a multi-target tracking algorithm.
And each video frame in the video is marked with the position of the target frame and the target label.
S320, extracting a plurality of video frames from the video.
And S330, extracting a pedestrian image corresponding to different contained pedestrians from each video frame based on the target label and the position of the target frame of the extracted video frame.
And S340, acquiring a plurality of pedestrian images with the same pedestrian corresponding to the plurality of video frames, and performing quality analysis on the plurality of pedestrian images to obtain quality scores corresponding to the plurality of pedestrian images respectively.
And S350, selecting the pedestrian image with the highest quality score from the multiple pedestrian images as the pedestrian image corresponding to the pedestrian.
In some examples, to further improve the accuracy of determining prevalence trends. Multiple video frames may be extracted from the video for each target product. At least one pedestrian may be included in each video frame.
After the plurality of video frames are extracted, a pedestrian image corresponding to a different contained pedestrian may be extracted from each video frame based on the position of the target tag and the target frame of the extracted video frame. Thus, a plurality of pedestrian images corresponding to each video frame can be obtained.
For example, assume that video frame a, video frame B and video frame C are extracted,
assuming that the video frame a contains a pedestrian a and a pedestrian B, the video frame B contains a pedestrian a, a pedestrian B, and a pedestrian C, and the video frame C contains a pedestrian B and a pedestrian C, images of pedestrians corresponding to the contained different pedestrians can be extracted from the video frame a, the video frame B, and the video frame C, respectively. Two pedestrian images including a pedestrian a, three pedestrian images including a pedestrian b, and two pedestrian images including a pedestrian c are obtained.
Then, a plurality of pedestrian images with the same pedestrian can be obtained from a plurality of pedestrian images corresponding to the plurality of video frames, and quality analysis is performed on the plurality of pedestrian images to obtain quality scores corresponding to the plurality of pedestrian images respectively.
In some examples, the purpose of quality analysis of the multiple pedestrian images is to determine a pedestrian image with better quality so as to perform a fashion trend analysis using the pedestrian image with better quality. When the pedestrian in the image is blocked, the image of the pedestrian is fuzzy and darker, or the pedestrian in the image is the side surface, the image quality is poor.
For example, two pedestrian images including the pedestrian a may be subjected to quality analysis, three pedestrian images including the pedestrian b may be subjected to quality analysis, and two pedestrian images including the pedestrian c may be subjected to quality analysis.
After the quality scores of the multiple pedestrian images including the same pedestrian are obtained, the pedestrian image with the highest quality score can be selected from the multiple pedestrian images to serve as the pedestrian image corresponding to the pedestrian.
For example, the pedestrian image with the highest quality score may be selected as the pedestrian image corresponding to the pedestrian a from the two pedestrian images including the pedestrian a, the pedestrian image with the highest quality score may be selected as the pedestrian image corresponding to the pedestrian b from the three pedestrian images including the pedestrian b, or the pedestrian image with the highest quality score may be selected as the pedestrian image corresponding to the pedestrian c from the two pedestrian images including the pedestrian c.
After obtaining the pedestrian image corresponding to each pedestrian, step S360 may be performed to extract the target product image from each pedestrian image.
In some examples, each pedestrian image may include one target product or a plurality of target products, and when one pedestrian image includes a plurality of target products, in a possible implementation manner of the embodiment of the present invention, the pedestrian image may be segmented by using a target product segmentation algorithm to obtain target product images corresponding to the target products at different wearing portions in the pedestrian image. Step S370 may then be performed.
By segmenting the pedestrian image, analysis can be performed only on the basis of the image containing the target product when popular trend analysis is performed, so that the size of the image can be reduced, the recognition rate can be increased, and the efficiency of popular trend analysis can be improved.
And S370, identifying each target product image to obtain the attribute value of each visual attribute of the target product in each target product image.
And S380, determining the popularity trend of the target product based on the attribute values of the visual attributes of the target product in each target product image.
It is understood that steps S310 and S360 to S380 in the embodiment of the present invention are similar to or the same as steps S210 and S230 to S250 in the second implementation manner in the embodiment of the present invention, and are not described again here.
On the basis of the analysis method for the product popularity trend shown in fig. 3, an embodiment of the present invention further provides a possible implementation manner, as shown in fig. 4, which is a flowchart of a fourth implementation manner of the analysis method for the product popularity trend shown in the embodiment of the present invention, and the method may include:
and S410, acquiring a video acquired by the video monitoring equipment by adopting a multi-target tracking algorithm.
And each video frame in the video is marked with the position of the target frame and the target label.
S420, a plurality of video frames are extracted from the video.
And S430, extracting a pedestrian image corresponding to the contained different pedestrians from each video frame based on the target label and the position of the target frame of the extracted video frame.
And S440, acquiring a plurality of pedestrian images with the same pedestrian corresponding to the plurality of video frames, and performing quality analysis on the plurality of pedestrian images to obtain quality scores corresponding to the plurality of pedestrian images respectively.
And S450, selecting the pedestrian image with the highest quality score from the multiple pedestrian images as the pedestrian image corresponding to the pedestrian.
And S460, extracting a target product image from each pedestrian image.
For example, assuming that the target product is a garment, a garment image may be extracted from each pedestrian image. In some examples, the garment may generally include a jacket, trousers, and shoes, and each pedestrian image may be segmented using a garment segmentation algorithm to obtain a jacket image corresponding to the jacket, a trousers image corresponding to the trousers, and a shoes image corresponding to the shoes in the pedestrian image.
S470, performing attribute identification on each target product image by adopting a target product classification algorithm to obtain the visual attribute of the target product in each target product image.
For example, the clothing classification algorithm may be used to perform attribute recognition on each image of a jacket to obtain the style and/or color of the jacket in each image of the jacket, the clothing classification algorithm may be used to perform attribute recognition on each image of trousers to obtain the style and/or color of the trousers in each image of the trousers, and the clothing classification algorithm may be used to perform attribute recognition on each image of shoes to obtain the style and/or color of the shoes in each image of the shoes.

In some examples, when identifying the attribute value of the visual attribute of the target product in the target product image, the attribute identification may be performed on each target product image by using a target product classification algorithm, so that the visual attribute of the target product in each target product image may be obtained.
In still other examples, the target product classification algorithm may be a pre-trained neural network algorithm. The neural network algorithm obtained by pre-training can be obtained by training by adopting a product image sample labeled with visual attributes.
In still other examples, a corresponding target product classification algorithm may be set for each target product, so that for the target product, the target product classification algorithm corresponding to the target product is used to determine the visual attribute of the target product.
By adopting the target product classification algorithm corresponding to each target product, the determined visual attribute can be more accurate, so that the accuracy of the subsequently determined popular trend can be improved.
After the visual attributes of the target products in each target product image are obtained, the visual attributes of the target products in all the target product images in the image set can be analyzed, and the attribute values of the visual attributes of the target products in each target product image are obtained.
In some examples, for each visual attribute, a proportion of the visual attribute in the visual attribute of the target product in all of the images of the target product in the image set may be calculated and then used as the attribute value of the visual attribute.
For example, for each style, the ratio of the style to the styles of the target products in all the images of the target products in the image set may be calculated, and then the ratio may be used as the attribute value of the style. Then, through step S490, the most popular style or more popular styles are determined.
For another example, for each color, the ratio of the color to the color of the target product in all the target product images in the image set may be calculated, and then the ratio may be used as the attribute value of the color. The most popular colors or more popular colors are then determined, via step S490.
For example, the style and/or color of the upper garment in all the upper garment images in the image set may be analyzed to obtain the attribute value of the style and/or color of the upper garment in each upper garment image, the style and/or color of the trousers in all the trousers images in the image set may be analyzed to obtain the attribute value of the style and/or color of the trousers in each trousers image, and the style and/or color of the shoes in all the shoe images in the image set may be analyzed to obtain the attribute value of the style and/or color of the shoes in each shoe image.
And S490, determining the popularity trend of the target product based on the attribute values of the visual attributes of the target product in each target product image.
For example, the fashion trend and/or the color trend of the jacket may be determined based on the attribute value of the style and/or the color of the jacket in each jacket image, the fashion trend and/or the color trend of the trousers may be determined based on the attribute value of the style and/or the color of the trousers in each trousers image, and the fashion trend and/or the color trend of the shoes may be determined based on the attribute value of the style and/or the color of the shoes in each shoe image.
