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 personalized special effects to the frame images in the video well and accurately, so The resulting processed video data is poorly displayed

The invention discloses a method, device, computing device and computer storage medium for real-time processing of video data based on adaptive threshold segmentation. The method includes: acquiring a current frame image containing a specific object in a video in real time; performing scene segmentation on the current frame image Processing to obtain the foreground probability information for a specific object, determine the proportion of the foreground area according to the foreground probability information, and perform mapping processing on the foreground probability information according to the proportion of the foreground area, and obtain the image segmentation result corresponding to the current frame image; according to the image Segment the result and determine the processed foreground image; add personalized special effects according to the processed foreground image to obtain a frame processed image; cover the frame processed image with the current frame image to obtain processed video data; display the processed video data. This technical solution improves the segmentation accuracy and processing efficiency of image scene segmentation, and can add personalized special effects to frame images more accurately and quickly based on image segmentation results.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a video data real-time processing 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 perform personalized processing such as changing the background of the video, adding special effects, etc., the image segmentation method is often used to perform scene segmentation processing on the frame images in the video. Among them, the image segmentation method based on deep learning is adopted The segmentation effect at the pixel level can be achieved. 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 ...
