It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Fig. 1 is a flow diagram of a video generation method according to some embodiments of the invention. As shown in fig. 1, the video generation method of this embodiment includes steps S102 to S106.
In step S102, an original image and a mask video are acquired, wherein the mask video includes one or more mask images.
The original image refers to an image used to generate a video. For example, a product exhibition video is generated using a product image as an original image, a personal introduction video or an electronic album is generated using a life photograph as an original image, and the like.
The mask video is used to add video effects to the video generated from the original image. When a new effect is added to a video, only a new mask video needs to be generated or acquired, and a template special for a certain tool does not need to be made by writing a program or the like.
In some embodiments, one or more mask images may be generated or acquired and then a mask video including these mask images is generated. Each mask image may play one or more frames.
In some embodiments, the mask image is a binarized image. The binarized image includes only black pixels having a gradation value of 0 and white pixels having a gradation value of 1. For example, it can be determined from such a mask image which pixels are displayed in the original image and which pixels are hidden.
In step S104, for each frame of mask image in the mask video, pixel information of pixels located at the same position in the processed image corresponding to the mask image is determined based on pixel information of pixels located at the same position in the mask image and the original image. The pixel information may be a pixel value, a gray value, an RGB (Red Green Blue) value, a transparency, and the like. The type of pixel information can be selected as desired by those skilled in the art.
As shown in FIG. 2, the pixels 210 in the original image 21 and the pixels 220 in the mask image 22 are both in the second row and the second column. Then, when the original image 21 is processed from the mask image 22, the pixel information of the pixel 230 in the processed image 23 is determined from the pixel information of the pixel 210 and the pixel 220. The pixels 230 are also located in a second row and a second column.
In some embodiments, the above processing may be implemented by calling one or more interfaces provided by opensource computer vision Library (OPENCV).
In step S106, a video is generated from the processed image corresponding to each frame of mask image. That is, each frame in the generated video is a respective processed image.
In some embodiments, the process of generating a video from a processed image corresponding to each frame of mask image may be implemented by calling an interface of FFMPEG (Fast Forward MPEG, MPEG stands for Moving Picture Experts Group, which is collectively referred to as Moving Picture Experts Group).
By the method of the embodiment, the original image can be processed by using the mask video, and the video is generated according to the processed image, so that automatic addition of video effects and automatic generation of the video can be realized. Moreover, the mask video is convenient to manufacture, and the learning cost and the video manufacturing time of a user are reduced. Thus, the efficiency and the applicability of video generation are improved.
FIG. 3 is a flow diagram illustrating a method of raw image processing according to some embodiments of the invention. As shown in fig. 3, the original image processing method of this embodiment includes steps S302 to S304.
In step S302, the pixel information of the pixels at the same position of the mask image and the original image is subjected to a predetermined operation.
For example, the mask image may be multiplied by the pixel information of the pixels at the same position of the original image to proportionally process the pixel information of the original image according to the pixel information of the mask image; alternatively, the pixel information of the pixels on the same position of the mask image and the original image may be added to perform the superimposition processing on the original image and the mask image. The operation mode can be selected by those skilled in the art according to the requirement, and is not described herein again.
In step S304, pixel information of pixels located at the same position in the processed image corresponding to the mask image is specified based on the calculation result.
In some embodiments, the operation result may be directly determined as pixel information of the processed image.
In some embodiments, a background image can be further superimposed on the operation result to obtain a richer video effect. For example, the sum of the pixel information of the pixels in the background image and the calculation result corresponding to the pixels at the same position may be determined as the pixel information of the pixels at the same position in the processed image corresponding to the mask image.
The background image may be other acquired original images or may be an image obtained by processing other original images. An embodiment of the present invention for superimposing other images in the process of processing an original image is described below with reference to fig. 4. In this embodiment, the mask image is a binarized image.
FIG. 4 is a flowchart illustrating a method of processing raw images according to further embodiments of the present invention. As shown in fig. 4, the original image processing method of this embodiment includes steps S402 to S408.
In step S402, a first multiplication operation is performed on pixel information of pixels at the same position of the mask image and the original image.
Since the mask image in this embodiment is a binarized image, after the first multiplication operation is performed, the black portion in the mask image makes the pixel information of the corresponding position in the original image 0, and the white portion makes the pixel information of the corresponding position in the original image unchanged.
In step S404, the inversion process is performed on the pixel information of each pixel in the mask image, and an inverted mask image is obtained. That is, a pixel having a pixel value of 0 in the mask image is converted into a pixel having a pixel value of 1, and a pixel having a pixel value of 1 is converted into a pixel having a pixel value of 0.
In step S406, a second multiplication operation is performed on the pixel information of the pixel at the same position on the inverted mask image and the acquired other original image.
Similarly to step S402, after the second multiplication operation, the black portion in the inverted mask image makes the pixel information of the corresponding position in the other original image 0, and the white portion makes the pixel information of the corresponding position in the other original image unchanged.
Steps S404 to S406 may be performed before step S402.
In step S408, the sum of the first multiplication result and the second multiplication result corresponding to the pixel at the same position is determined as the pixel information of the pixel at the same position in the processed image corresponding to the mask image.
As shown in fig. 5, the pixel information of the pixels at the same position of the original image 51 and the mask image 52 are subjected to a first multiplication operation, and the operation result can be intuitively represented by a first operation result image 53; the pixel information of the pixels at the same position of the other original image 54 and the inverted mask image 55 are subjected to a second multiplication operation, and the operation result can be visually represented by the second operation result image 56. The pixel information of the pixels at the same position in the first operation result image 53 and the second operation result image 56 are added to obtain a processed image 57. In the mask image 52 and the inverted mask image 55, dot-like background portions are black portions, and non-dot-like background portions are white portions.
It should be clear to those skilled in the art that the first operation result image 53 and the second operation result image 56 are merely used to pictorially explain the processing procedure of the above-described embodiment. In the application process, it is not necessary to generate the first operation result image 53 and the second operation result image 56, and only the operation results corresponding to the pixels of the respective positions may be saved.
The above-described embodiments can display information of an original image or another original image according to different pixel values in a binarized image. In some embodiments, the other original image may be the next image to the currently processed original image, so that a smooth transition between different original images may be achieved in the generated video.
FIG. 6 is a flow diagram illustrating a method of raw image processing according to some embodiments of the invention. As shown in fig. 6, the original image processing method of this embodiment includes steps S602 to S606.
In step S602, a preset operation corresponding to pixel information of a pixel of the mask image is determined.
For example, the correspondence between the pixel information and the preset operation may be established in advance. The correspondence relationship may include a correspondence relationship between a value of the pixel information or a value range to which the pixel information belongs and a preset operation.
In step S604, a corresponding preset operation is performed on the pixel information of the pixels at the same position of the original image.
In step S606, the result of the preset operation is determined as the pixel information of the pixels located at the same position in the processed image corresponding to the mask image.
The above-described embodiment may also be processed in combination with a binarized image as a mask image. In some embodiments, in a case where the pixel information of the pixel of the mask image is a preset value, the corresponding preset operation is to replace the pixel information of the pixel at the same position of the original image with the acquired pixel information of the pixel at the same position of another original image. For example, in the case where the pixel value of a pixel of the mask image is 0, the pixel information of the pixel at the same position of the original image may be replaced with the acquired pixel information of the pixel at the same position of another original image; when the pixel value of the pixel of the mask image is 1, the pixel information of the pixel at the same position in the original image is directly used as the pixel information of the pixel at the same position in the processed image.
In some embodiments, the other original image may be the next image to the current processed original image.
The above embodiments describe the processing manner of any one original image in the process of generating a video. Embodiments of the present invention may incorporate the methods of the above embodiments to automatically generate video using one or more raw images. An embodiment of the video generation method of the present invention is described below with reference to fig. 7.
FIG. 7 is a flow diagram illustrating a method of generating a video from a processed image according to some embodiments of the invention. As shown in fig. 7, the method of generating a video from a processed image of this embodiment includes steps S702 to S714.
In step S702, one or more original images and a mask video input by a user are acquired. If desired, an audio file input by the user may also be obtained as a soundtrack for the video.
In step S704, the mask video is resized to the same size as the original image.
In step S706, processing the nth original image by using the mask video specifically includes: and aiming at each frame of mask image in the mask video, determining the pixel information of the pixel at the same position in the processed image corresponding to the mask image according to the pixel information of the pixel at the same position of the mask image and the Nth original image.
The initial value of N is 1.
In step S708, the one or more frames of original images and the processed image corresponding to each frame of mask image are used as the set of video frames corresponding to the original images.
In step S710, it is determined whether N is equal to the number of original images, and if not, step S712 is performed; if so, step S714 is performed.
In step S712, 1 is added to the value of N and the process returns to step S706 to process the next original image.
In step S714, a video is synthesized using a set of video frames corresponding to one or more original images. When the user inputs audio, the audio may also be synthesized into the video.
By the method of the embodiment, the video with the visual effect can be automatically generated through the original image and the mask video input by the user, so that the video generation efficiency is improved.
