Problems solved by technology
However, the existing image segmentation method does not consider the proportion of the foreground image in the frame image when performing scene segmentation processing, so when the proportion of the foreground image in the frame image is small, it is easy to use the existing image segmentation method Divide the pixels that actually belong to the edge of the foreground image into the background image, and the resulting image segmentation results have low segmentation accuracy and poor segmentation effect
Therefore, the image segmentation method in the prior art has the problem of low segmentation accuracy of image scene segmentation, and the obtained image segmentation results cannot be used to add beautification effects to the characters in the video well and accurately. Display of processed video data is poor

The invention discloses a video figure dressing method and device based on adaptive threshold partitioning, computing equipment and a computer storage medium. The method comprises the steps that a current frame image containing a specific object in a video is acquired in real time; scene partitioning processing is performed on the current frame image, and foreground probability information of thespecific object is obtained; a foreground region ratio is determined according to the foreground probability information, and mapping processing is performed on the foreground probability informationaccording to the foreground region ratio to obtain an image partitioning result; a processed foreground image is determined according to the image partitioning result; at least one to-be-dressed region in the processed foreground image is determined according to the processed foreground image; a beautifying effect is added to the to-be-dressed regions, and a frame processed image is obtained; theframe processed image is used to cover the current frame image to obtain processed video data; and the processed video data is displayed. Through the technical scheme, the beautifying effect can be added to the to-be-dressed regions of the frame image more precisely.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a video character dressing method, device, computing device and computer storage medium based on adaptive threshold segmentation. Background technique [0002] In the prior art, when the user needs to personalize the video, such as adding beautification effects to the characters in the video, the image segmentation method is often used to perform scene segmentation processing on the frame images in the video. The learned image segmentation method can achieve pixel-level segmentation effect. However, the existing image segmentation method does not consider the proportion of the foreground image in the frame image when performing scene segmentation processing, so when the proportion of the foreground image in the frame image is small, it is easy to use the existing image segmentation method The pixels that actually belong to the edge of the foreground image are di...
