WIPO Patent Application WO/2018/141232
Kind Code:
A1
Abstract:
Provided are an image processing method and computer device and storage medium; the image processing method of one embodiment comprises: a terminal obtaining a to-be-processed image, new background image, and curtain image; according to said to-be-processed image and said curtain image, the terminal determining the foreground pixel probability of each pixel in the to-be-processed image being a foreground pixel as well as the background pixel probability of each pixel in the to-be-processed image being a background pixel; according to the foreground pixel probability and background pixel probability of each of said pixels, the terminal determining the pixel type of said pixels, said pixel types comprising foreground pixel, background pixel, and mixed pixel; according to the mixed pixels, the foreground pixel probability of said mixed pixels, and the curtain image, the terminal determining a merged weighted value of each of said mixed pixels, and according to the merged weighted value of each of the mixed pixels, determining the foreground component value of each of the mixed pixels. The terminal takes the pixel values of said foreground pixels to be the pixel values of pixels at positions corresponding to the foreground pixels of an image after the background has been replaced; takes the pixel values of the pixels at the positions corresponding to the background pixels in the new background image to be the pixel values of pixels at positions corresponding to the background pixels of the image after the background has been replaced; according to the merged weighted values and foreground component values of the mixed pixels as well as the pixel values of the new background pixels, determines merged pixel values of the mixed pixels, and takes said merged pixel values to be the pixel values of pixels at positions corresponding to the mixed pixels of the image after the background has been replaced. Using the present embodiment it is possible to obtain a divided result in which a foreground image is stably extracted, such that when replacing a background, image quality ultimately obtained after the background has been replaced is high.
