In a specific implementation, the target images and the background image may be fused by an image fusion technique to obtain a group image including the target background and the target objects.
Here, in generating the group image, in order to better fuse each target object in the image having the target background, the size of the target image of each target object may be set to be the same as the size of the background image.
In a specific implementation, after the pixel value of the second image area except the first image area where the target object is located in the first image is adjusted to 0 based on the above S102, in order to ensure that the position of each target object in the target image is the same as the position of each target object in the group-photo image, the target image and the background image may be fused by the following method to obtain a group-photo image including the target background and each target object, which is specifically described as follows: traversing pixel points at a first position in the target image; if the pixel value of the pixel point at the first position is the first pixel value, determining the pixel value at the position in the group image, which is the same as the first position, as the first pixel value; and if the pixel value of the pixel point at the first position is the second pixel value, identifying a third pixel value of the pixel point at the first position in the background image, and determining the pixel value at the same position as the first position in the group image as the third pixel value.
Wherein the first position is used for representing any position in the target image; here, the first pixel value is used to represent a pixel value of a pixel point at any position in the region where the target object is located in the target image, and for example, the first pixel value may be set to be not equal to 0; the second pixel value is used to represent the pixel value of the pixel point in any position in the other region except the region where the target object is located in the target image, and for example, the second pixel value may be set to be equal to 0; the third pixel value is used for representing the pixel value of the pixel point at any position in the background image and can be set according to actual requirements.
Here, the first person image region may be used to represent a region in which the target object is located in the target image; the method comprises the steps that a first background area is adopted to represent other areas except the area where a target object is located in a target image; adopting a second portrait area to represent an area in the group photo image, wherein the area has the same position as the area of the target object in the target image; and adopting the second background area to represent the areas in the group photo image, wherein the positions of the areas are the same as those of other areas except the area of the target object in the target image.
For example, since the pixel values of the second image area except the first image area where the target object is located in the first image are adjusted to 0 based on the above S102, it may be determined that the area where the pixel value is not 0 in the target image is the area where the target object is located (i.e., the first person area); taking the pixel value of each pixel point in the first portrait area in the target image as the pixel value of each pixel point corresponding to the second portrait area in the group photo image; and the pixel value of each pixel point in the area with the same position as the second image area in the background image is used as the pixel value of each pixel point corresponding to the second background area in the group photo image, so that the pixel value of the pixel point at each position in the group photo image is determined, and the group photo image is obtained.
In an optional embodiment, in order to ensure that the position of each target object in the target image is the same as the position of each target object in the group photo image, the target image and the background image may be fused by the following method to obtain a group photo image including the target background and each target object, which is specifically described as follows: and determining the pixel value at the same position in the group image based on the transparency and the pixel value at the same position in each target image and the background image.
Here, the transparency of the pixel point at each position may be used as a weight of the pixel point, and the pixel values of the pixel points at the same position in each target image and the background image are subjected to weighted summation to obtain the pixel value of the pixel point at each position in the group image.
Here, the third portrait area may also be used to represent an area in the background image that is at the same position as the area of the target object in the target image; and adopting the third background area to represent the areas in the background image, which are at the same positions as the areas except the areas of the target objects in the target image.
Here, the first transparency of the first portrait area in each target image may be set to 1, and the second transparency of the first background area in each target image may be set to 0; and setting the third transparency of the third portrait area in the background image to 0 and setting the fourth transparency of the third background area in the background image to 1.
Specifically, the pixel value of each pixel point corresponding to the second portrait area in the group photo image is obtained by multiplying the pixel value of each pixel point in the first portrait area in the target image by the first transparency and adding the product of the pixel value of each pixel point corresponding to the third portrait area in the background image by the third transparency (that is, the pixel value of each pixel point in the first portrait area in the target image is used as the pixel value of each pixel point corresponding to the second portrait area in the group photo image); multiplying the pixel value of each pixel point in the first background area in the target image by the second transparency, and adding the product of the pixel value of each pixel point in the third background area in the background image by the fourth transparency to obtain the pixel value of each pixel point corresponding to the second background area in the group image (i.e. the pixel value of each pixel point in the third background area in the background image is used as the pixel value of each pixel point corresponding to the second background area in the group image); and determining the pixel value of the pixel point at each position in the group photo image to obtain the group photo image.
In specific implementation, in order to meet the group photo requirements of different users, each user participating in the group photo can customize a background image according to the needs of the user, so as to obtain a group photo image meeting the needs of the user, which is specifically described as follows: responding to the selection operation of a first target object in each target object, and acquiring a first background image corresponding to the selection operation; based on each target image and the first background image, a first group image including the first background image and each target object is generated.
Wherein the first target object is used for characterizing any one of a plurality of target objects participating in the co-illumination; the first background image is used for representing a target background image customized by the user or a target background image selected by the user in a plurality of provided background images.
Specifically, in the process of generating the group photo image, after a first background image is set on a terminal device of any one of a plurality of target objects participating in group photo, or a large-screen electronic device deployed in a fixed shooting place, or a shooting device deployed in the fixed shooting place according to requirements (or a favorite first background image is selected from a plurality of background images provided according to preferences), the first background image is sent to the server, so that the server performs fusion processing on the acquired first background image and the target images corresponding to the target objects to obtain the group photo image including the first background image and the target objects.
Here, after the group photo image including the first background image and each target object is obtained, the group photo image may be transmitted to each user participating in the group photo, or only the group photo image may be transmitted to the target user who customizes or selects the first background image.
Exemplarily, if the first background image customized by the user a is a landscape image, and the two first images obtained by the user a and the user b and respectively put out the corresponding group-taking model according to the target group-taking formation and the target group-taking posture are subjected to image segmentation, processing and fusion shown in S102 to S103 to obtain a group-taking image including the user a, the user b and the first background image, and the group-taking image is sent to the terminal device of the user a, the terminal device of the user a shows the group-taking image to the user a, and a specific showing interface may be shown in fig. 5, taking the terminal device as a mobile phone as an example, and the showing interface includes the user a, the user b and the landscape image which are put out the corresponding group-taking formation according to the target group-taking formation and the target group-taking posture; here, the target photographic formation and the target photographic pose in fig. 5 may be the same as the target photographic formation and the target photographic pose shown in fig. 3.
