Abstract
Disclosed are method and apparatus for video watermarking, an electronic device and a storage medium. The method includes steps described below. Image data of a target video frame is converted from an RGB format to a YUV format; in the YUV format, an offset with a preset value is superimposed on a pixel value of a pixel point corresponding to a shape be watermarked on the target video frame; and the target video frame on which the offset is superimposed is encoded.
Claims21
A method for video watermarking, comprising:
- converting image data of a target video frame from a red-green-blue (RGB) format to a luma and chroma (YUV) format;
- superimposing, in the YUV format, an offset with a preset value on a pixel value of a pixel point corresponding to a shape to be watermarked on the target video frame;
- and
- encoding the target video frame on which the offset is superimposed.
