Abstract

The invention relates to a performance analysis method and device for an electronic anti-shake (EIS) algorithm and belongs to the field of electronic technology application. According to the method, rolling shutter distortion of each image in multiple images included in video sample data can be calculated, and the performance of the EIS algorithm can be determined according to the calculated rolling shutter distortion of all the images, wherein the performance of the EIS algorithm is in negative correlation with the size of the rolling shutter distortion, and the size of the rolling shutter distortion is in positive correlation with fluctuation degrees of motion vectors of all feature points in each image. Since the fluctuation degrees of the motion vectors of all the feature points in each image can accurately reflect whether rolling shutter distortion exists in the video sample data, the performance of the EIS algorithm can be accurately reflected through the rolling shutter distortion. Moreover, through the analysis method, a developer does not need to observe a video with eyes, and analysis efficiency and precision are effectively improved.

Description

technical field [0001] The present disclosure relates to the application field of electronic technology, in particular to a performance analysis method and device of an electronic anti-shake algorithm. Background technique [0002] Electronic anti shake (EIS) algorithm is a commonly used algorithm for improving the shaking problem when a mobile device records a video. Through the EIS algorithm, the picture stability of the video recorded by the mobile device can be effectively improved, and the display effect of the video can be improved. [0003] In the related art, after the developer completes the development of the EIS algorithm, he can apply the EIS algorithm to the test equipment and observe the video recorded by the test equipment. When the developer observes obvious jitter in the video recorded by the test device, it can be determined that the performance of the EIS algorithm is poor, and further corrections can be made to the EIS algorithm. [0004] However, the m...
