Until now, the existing image selection method for the designated category is not to select the image manually, so that the image selection process is too complicated, time-consuming and labor-consuming; if the images are not selected randomly, the selected images are not the images of the kind designated by the user, and the accuracy of image selection is low. Therefore, the present application provides an image selecting method, an image selecting device, a storage medium, and a terminal, so as to solve the problems in the related art. In the technical scheme provided by the application, each second image in the second image library, the corresponding image category and the mapping relation between each second image and the corresponding image category are identified to obtain corresponding identification information; and responding to a first selection instruction of the user for selecting the images of the designated category, and selecting at least one designated image from the second image library as the designated image selected by the user according to the identification information. Because the identification information capable of identifying each second image, the corresponding image category and the mapping relationship between each second image and the corresponding image category in the second image library is introduced, the selected specified image can be accurately indexed according to the identification information, at least one specified image is quickly and intelligently selected from the second image library to serve as the specified image selected by the user, and the following description is given in detail by adopting an exemplary embodiment.

The image selecting method provided by the embodiment of the present application will be described in detail below with reference to fig. 1. The method may be implemented in dependence on a computer program, and may be run on an image selection device. The computer program may be integrated into the application or may run as a separate tool-like application.

Referring to fig. 1, a flow chart of an image selecting method according to an embodiment of the present application is shown. As shown in fig. 1, the image selecting method according to the embodiment of the present application may include the following steps:

s101, a first image library is constructed by a plurality of first images acquired by a plurality of image acquisition devices.

In this step, the plurality of first images are acquired by a plurality of image acquisition devices respectively arranged in a preset area, and there is no overlapping acquisition area between the plurality of image acquisition devices.

In an actual application scenario, the image capturing device may be a camera with a shooting function.

For example, in a specific application scenario, twenty cameras are arranged in a cell, so that the twenty cameras arranged in the cell can acquire a plurality of first images, and there is no overlapping acquisition area between the twenty cameras, so that the phenomenon of repeatedly acquiring images between any first image and other first images in the first image library is avoided.

In this step, each first image in the first image library is an original image acquired by the image acquisition device, and is an image without any image processing.

S102, preprocessing each first image in the first image library according to the preprocessing model to obtain a corresponding second image, and constructing a second image library by the plurality of second images.

In a possible implementation manner, the preprocessing model includes a first preprocessing model capable of highlighting at least one key information element in the set of key information elements, and the preprocessing each first image in the first image library according to the preprocessing model to obtain a corresponding second image includes the following steps:

and according to the first preprocessing model, performing first preprocessing on each first image in the first image library to obtain a corresponding second image with at least one key information element highlighted, wherein the first preprocessing is preprocessing for highlighting the at least one key information element.

In this step, the at least one key information element includes at least one of:

a feature information element of the subject object in the first image, a facial expression information element of the subject object in the first image, and an accessory information element of the subject object in the first image.

In addition to the above-mentioned key information elements, other key information elements may be used, and the meaning of the key information elements is not particularly limited.

In a specific scene, when the first image is a picture of a white california, one key information element may be: and highlighting the hair characteristic information element corresponding to the white hair of the white Garfield cat, and performing filter processing on the background color of the picture through a first preprocessing process for highlighting the hair characteristic information element to obtain a corresponding second image.

In the second image, the background color blue background color clearly corresponds to the white hair of the cauda in the picture, and highlights the snow white hair of the cauda.

The first preprocessing process described above is merely an example, and is not described herein again. The first preprocessing process corresponding to the first preprocessing model can be adjusted according to the requirements of different specific application scenarios, which is not described herein again.

It should be noted that the first preprocessing model is a model established according to a conventional model building method, and details of the model building method are not described herein. A general method of building a model includes a training set and a testing set. And constructing an initial training model according to the image data in the training set, testing the initial training model according to the image data in the testing set, and continuously correcting to obtain a corrected training model.

In one possible implementation, before preprocessing each first image in the first image library according to the first preprocessing model, the method further includes the following steps:

reading at least one key information element;

wherein the key information elements include at least one of:

In addition to the above-mentioned key information elements, other key information elements may be used, and the meaning of the key information elements is not particularly limited. For the description of the key information elements, please refer to the foregoing description, which is not repeated herein.

In another possible implementation manner, the preprocessing model includes a second preprocessing model capable of removing at least one unrelated background object and/or background person, and the preprocessing each first image in the first image library according to the preprocessing model to obtain a corresponding second image further includes the following steps:

and according to the second preprocessing model, carrying out second preprocessing on each first image in the first image library to obtain a corresponding second image with at least one background object and/or background person removed, wherein the second preprocessing is preprocessing for removing at least one unrelated background object and/or background person.

In a specific application scenario, when the current first image includes at least one unrelated background object and/or background person, for example, when the current first image includes the unrelated background object and a cup, second preprocessing is performed on the current first image according to the second preprocessing model, the cup is removed, and the current first image is replaced with a complete background picture selected by a user, so that a second image with the unrelated background object (the cup) removed is finally obtained.

The above only illustrates an application scene in which the water cup is an unrelated background object in a certain application scene. In other application scenarios, the unrelated background object may also be a flower, or a background object such as a fan that is unrelated to the main object in the first image, and will not be described herein again.

It should be noted that the second preprocessing model is a model established according to a conventional model building method, and details of the model building method are not described herein. A general method of building a model includes a training set and a testing set. And constructing an initial training model according to the image data in the training set, testing the initial training model according to the image data in the testing set, and continuously correcting to obtain a corrected training model.

The above only illustrates two kinds of preprocessing processes, and in addition to the two listed preprocessing processes, other preprocessing processes may be adopted, which is not described in detail herein.

S103, classifying each second image in the second image library according to a preset neural network model for classifying the images to obtain a corresponding image category.

In this step, the preset neural network model is a neural network model constructed based on the VGG model, the classification accuracy of the model is more accurate, and the images can be accurately classified from the second image library, for example, which images are all images belonging to the class of automobiles and which images are all images belonging to the class of pet dogs.

Because the number of network layers of the VGG model is more and the convolution kernel is smaller, more image features can be extracted, and the accuracy rate of image classification is further improved. However, because the complexity of the VGG model network is high, the training process for constructing the model is also longer, and in addition, the requirements on the performance of computer hardware are also higher.

In a specific application scenario, different preset neural network models can be selected according to the number of second images in the second image library. For example, in a case where the number of second images in the second image library is not large and the recognition accuracy of the image classification is required to be high, the VGG model described above may be selected.

In practical applications, the VGG model has the following advantages:

a small convolution kernel; the convolution kernel is replaced by 3x3 (rarely using 1x 1);

pooling nuclei; compared with the 3x3 pooling nucleus of AlexNet, VGGs are all 2x2 pooling nuclei;

the characteristic diagram with deeper layer number is wider; because the convolution kernel is focused on expanding the number of channels and pooling is focused on narrowing the width and height, the increase of the calculated amount is slowed down while the model architecture is deeper and wider;

converting full connection into convolution; in the network testing stage, three full connections in the training stage are replaced by three convolutions, and the testing reuses parameters in the training process, so that the full convolution network obtained by testing has no limitation of full connections, and thus, can receive input with any width or height.

In another specific application scenario, under the conditions that the number of second images in the second image library is large and the requirement on the identification accuracy of each image is not high, an optimized convolutional neural network can be selected. For example, a picture of the convolutional neural network input layer is set to be a picture with a preset size, feature extraction is performed on the picture through the convolutional layer, and the image dimensionality is reduced through the pooling layer. Here, the first preset size of the picture is not particularly limited. The input of the layer 2 convolution is the output of the layer 1 convolution, and the size is a second preset size, and here, the second preset size is not particularly limited. The 3-5 layers of the convolution layer have the same structure, the link mode of the convolution layer and the subsequent pooling layer is not adopted any more, and the full convolution mode is adopted, so that the image characteristics are extracted as much as possible. Before the data is transmitted into the full connection layer, the data obtained by the previous layer is flattened, and the multidimensional input is one-dimensional, so that the link effect of the full connection layer is better. The number of ganglion points of the output layer is determined according to actual classification requirements. In addition, the classification process is also continuously optimized, and the method for optimizing the classification process is a conventional method, which is not described herein again.

And S104, identifying each second image in the second image library, the corresponding image category and the mapping relation between each second image and the corresponding image category to obtain corresponding identification information.

In this step, the identification information may identify, in addition to the above information, time information of image acquisition by the image acquisition device in order to realize accurate positioning of each second image; the time information may be embodied as: a certain time of a certain day.

For another example, the address information for image capturing by the image capturing device is identified: the address information may be specific to: in a building of a cell.

And S105, responding to a first selection instruction of the user for selecting the images of the designated category, and selecting at least one designated image from the second image library according to the identification information to be used as the designated image selected by the user.

In practical applications, the selected designated image may be one or multiple designated images, and the number of the designated images is not particularly limited.

In one possible implementation, after at least one designated image is selected from the second image library according to the identification information, the method further includes the steps of:

and responding to a second selection instruction of the user for selecting the appointed display equipment, and displaying the selected at least one appointed image on the corresponding display equipment, wherein the second selection instruction carries the MAC address information of the appointed display equipment.

In this step, the precise positioning of the specified display device can be realized through the MAC address information of the display device.

In one possible implementation manner, the step of displaying the selected at least one designated image on the corresponding display device includes the following steps:

under the condition that the number of the designated images is two or more, respectively calculating the weight value of each designated image;

sequencing each appointed image according to the image weight value of each appointed image;

and displaying each appointed image on the corresponding position of the appointed display equipment according to the corresponding relation between the image sequence and the display position of the image on the appointed display equipment.

In practical application, when two or more designated images are selected, the method for calculating the weight value of each designated image is a conventional method, and is not described herein again.

After the weight values of the respective designated images are obtained, the weight values of the respective designated images are sorted. In practical applications, a first designated image having a largest weight value of the designated images is arranged at the forefront, and the designated image corresponding to the weight value is displayed in a central area of the designated display device, while a second designated image having a smallest weight value is displayed in a boundary area of the designated display device, for example, an upper boundary, or a lower boundary, or a left boundary, or a right boundary. Here, only one display method is illustrated, and other display manners may also be provided, for example, a first designated image with a largest weight value is displayed on the uppermost layer of the designated display device, and a second designated image with a smallest weight value is displayed on the next layer of the first designated image, so as to avoid mutual occlusion between images, transparency of a display layer of each image may be set, for example, transparency is set to fifty percent, and a display method may also be modified according to different application scenarios, which is not described herein again.

In the embodiment of the application, each second image, the corresponding image category and the mapping relationship between each second image and the corresponding image category in the second image library are identified to obtain corresponding identification information; and responding to a first selection instruction of a user for selecting the images of the designated categories, and selecting at least one designated image from the second image library according to the identification information to serve as the designated image selected by the user. Therefore, the selected designated images can be accurately indexed according to the identification information, and at least one designated image can be quickly and intelligently selected from the second image library to serve as the designated image selected by the user.
