Problems solved by technology

[0003] However, the image mark extraction method in the prior art will not be accurate and the extraction effect will be weak for the edge of the semi-transparent image feature area, because it has part of the information that changes with the background content, so the traditional extraction method based on color information will be inaccurate. its use brings limitations
[0004] To sum up, the prior art image markers have the problem of weak extraction effect on semi-transparent markers in the image area

Abstract

The present application provides an image mark extraction method, device and storage medium, the method comprising: during the video playback process, acquiring continuous video images of preset frames; determining the grayscale image corresponding to each frame of the video image, and obtaining the preset Frame grayscale image; use preset algorithm to determine edge feature point information from grayscale image; extract image logo from video according to edge feature point information of preset frame grayscale image, thereby improving the efficiency of semi-transparent image logo extraction in video Accuracy, simple method, good extraction effect.

Description

technical field [0001] The present application relates to the field of display technology, to the field of image processing, in particular to an image mark extraction method, device and storage medium. Background technique [0002] In image recognition and image analysis, edge information can well describe the contour shape of objects. Edge detection can not only extract the shape features of the object itself, but also greatly reduce the amount of data that needs to be processed for subsequent image analysis. Therefore, image edge detection is a very important technology in image processing, and it has been widely used in target recognition, Target tracking, fingerprint recognition and other fields. [0003] However, the image mark extraction method in the prior art will not be accurate and the extraction effect will be weak for the edge of the semi-transparent image feature area, because it has part of the information that changes with the background content, so the tradi...
