Problems solved by technology

[0002] In mobile shopping applications, the main picture of the product is usually used to represent the product. The disadvantage is that it is too single and only one angle of the product can be seen
Therefore, some e-commerce platforms currently use product main image videos, but the disadvantage of this method is that it takes up too much bandwidth

Abstract

The present disclosure relates to a method and device for judging the rotation direction of an object. The method for judging the rotation direction of the target includes: inputting continuous video frames including the rotating target; establishing a background model according to the first frame image in the video frame; Perform foreground detection to determine the rotation axis of the rotating target; obtain the distribution of optical flow points in the preset area of ​​the rotation axis; determine the rotating target according to the distribution of optical flow points in the preset area direction of rotation. The present disclosure can simply and efficiently determine the clock direction of a rotating object in a video.

Description

technical field [0001] The present disclosure relates to the technical field related to video image processing, and in particular to a method and device for judging the rotation direction of an object, a computer-readable medium, and an electronic device. Background technique [0002] In mobile shopping applications, the main image of the product is usually used to represent the product. The disadvantage is that it is too single and only one angle of the product can be seen. Therefore, some e-commerce platforms currently use product main picture videos, but the disadvantage of this method is that it takes up too much bandwidth. [0003] Therefore, there is still room for improvement in the prior art. [0004] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to those of ordinar...
