Image data processing method, device and electronic equipment

Abstract

The present application provides an image data processing method, device and electronic equipment. The method includes: determining the search center point and the maximum search estimate radius of the target image, and setting at least two levels of search radii with different values ​​within the maximum search estimate radius; Search for the first pixel that meets the first matching requirement within the first search radius selected from the search radius; when the first pixel is found, within the preset area centered on the first pixel Search for a second pixel point that meets the second matching requirement; when the second pixel point is found, use the second pixel as the matching position point of the matched target image. Utilizing various embodiments in the present application, it is possible to quickly match to the required position of the target image while ensuring the matching accuracy, greatly reduce the number of matching calculations, reduce the processing load, increase the matching speed, and improve the user experience.

Description

Technical field [0001] This application relates to the field of video image data processing, and in particular to an image data processing method, device and electronic equipment. Background technique [0002] With the rapid development of the smartphone market, users often need to track and locate targets in the collected video when using mobile terminals to take photos, selfies, and videos, such as face tracking during selfies. In this way, the shooting target in the video can be automatically tracked and locked with the movement of the terminal or the target, which can provide users with convenience and better perception of the use effect. [0003] In the tracking scene of a video target, image block matching is one of the processing methods mainly used in the prior art. Video is usually composed of multiple video frames arranged in time sequence. After the target image block of the current frame is acquired, it can be used as a reference image block for image block matching in...

Problems solved by technology

However, this strategy of traversing and searching the target area often leads to a large amount of calculation, especially if the tracking target moves a lot during the tracking process, in order to ensure the accuracy of matching, the search radius is often increased by a large increase, that is, increasing A large (range_max) value will obviously lead to a sharp increase in the number of image block matches, an increase in the amount of data processing, and a decrease in matching speed

At the same time, for terminal processing equipment, such a large number of calculations will increase the processing load, which will cause the risk of heating and freezing of the terminal, and reduce the user experience of APP or terminal equipment.

[0004] In the prior art, the image block processing method of video object tracking has many matching times, and the amount of data calculation is large, which increases the processing load, leads to low processing efficiency, and even often causes problems such as heating and freezing of terminal equipment, reducing user usage. to experience
