High-altitude parabolic frame difference method moving target detection smear removal method

The invention discloses a high-altitude parabolic frame difference method moving target detection smear removal method, relates to the technical field of image processing and security and protection, and is used for solving the problem that the existing high-altitude parabolic detection algorithm is low in complexity and has a smear phenomenon, so that a part of non-moving areas are foreground-recognized, and further parabolic misrecognition is caused. According to the invention, frame difference absolute value calculation is carried out on a current frame and a previous frame of a video stream, and binarization is carried out by using a threshold to obtain a motion foreground image of the current frame; extracting a closed foreground region from the moving foreground image through a contour edge extraction algorithm, calculating the area of the foreground region, and filtering the foreground region by using an area threshold value to obtain a foreground region meeting the area between a minimum value and a m
