The invention discloses an image feature search method and device. The method comprises the steps of respectively splitting a current frame and a reference frame into multiple units; comparing units at the same positions of the current frame and the reference frame pixel by pixel and judging whether the two units at the same positions are the same units or not; and for the same units, copying the feature information of the unit of the reference frame to a feature information table of the unit at the same position of the current frame. According to the method and the device, the problem that according to the image feature search method in the prior art, the calculation volume is increased and the search speed is slow due to the fact that all existing features need to be searched is solved, a great deal of redundant calculation is eliminated, and the search speed is improved.
Description
technical field [0001] The present invention relates to the field of image processing, in particular to an image feature search method and device, a storage medium and a processor. Background technique [0002] When compressing continuous multi-frame computer screen or mobile terminal screen images, there are two processing methods. One method is to compress each frame image independently, which is denoted as I method here, and the other method is to only compress each frame image. The new content in the frame image is compressed, and the same part only encodes the reference image index and offset position information. This is a prediction method, which is recorded as P method here. For the I mode, it is generally used to encode the first frame image in consecutive multi-frames, and the decoder can directly restore all the information; for the P mode, it is suitable for images other than the first frame, and the decoder finds the information from the decoded image. Refer to...
