Title:
VIDEO PROCESSING METHOD FOR MAKING STEALTH SPECIAL EFFECT, FILTER, DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/179487
Kind Code:
A1
Abstract:
The present invention is applicable to the technical field of image processing, and provides a video processing method for making a stealth special effect, a stealth filter, a device, and a storage medium. The method comprises: converting a video frame of a video to be processed from an RGB color space to a preset color brightness separation color space, wherein a region to be subjected to stealth in the video to be processed is shielded by a curtain; obtaining a Mask region of each video frame according to a tone interval corresponding to the curtain; performing morphological processing on each Mask region; obtaining a replacement weight corresponding to each pixel in each Mask region which is subjected to morphological processing: and respectively performing weighted replacement on the values of R, G, and B channels of each pixel in the Mask region according to the replacement weight and the extracted background frame to generate a video containing the stealth special effect, thereby improving the making effect of the stealth special effect.
