Problems solved by technology

However, the performance of the moving target detection algorithm reflected by them is different. We cannot objectively evaluate the performance of the moving target detection algorithm based on a certain index alone, and there will be a detection In the case where one index of the algorithm is the best and another index of another detection algorithm is the best, there may even be situations where the conclusions of the two indexes are just opposite, which will confuse the judges, and it is also not convenient for the moving target detection algorithm Objective judgment of final inspection performance

Embodiment Construction

[0050] Step 1. According to the standard detection picture A (provided by the Wallflower data set, as a standard reference), the number of standard foreground points Nu is obtained, and then the algorithm detection picture B (picture detected by the moving object detection algorithm) and the standard detection picture The number of correct foreground points TP detected by the algorithm and the number FP of background points misjudged as foreground points are obtained by one-to-one correspondence between the pixels of A; Nu is the number of pixels in the target position area in the standard detection picture A; TP is the number of target points detected in the target position area of ​​the corresponding standard detection picture A in the algorithm detection picture B; FP is the number of target points detected in the background position area of ​​the corresponding standard detection picture A in the algorithm detection picture B; The closer the value of TP is to the value of A,...

Abstract

The invention provides a moving target detection algorithm performance evaluating method based on visual perception. The method is characterized in that a standard detection picture is selected; for every different moving target detection algorithm, an algorithm detection picture is obtained and is compared with the standard detection picture to obtain an evaluation index of the algorithm; the obtained evaluation indices of different algorithms are sorted in a descending order; and the algorithm corresponding to the minimum is the best in performance.

Description

technical field [0001] The invention relates to an image processing technology, in particular to a method for evaluating the performance of a moving target detection algorithm based on visual perception. Background technique [0002] As a preprocessing link in many computer vision applications, moving target detection has important applications in fields such as video surveillance and video search. While attracting more and more people's attention, moving target detection based on different theories has Detection algorithms are constantly being proposed. Therefore, establishing a unified and objective standard data set and evaluation criteria to evaluate the performance of existing moving object detection algorithms objectively and fairly plays an important role in understanding, improving and proposing new algorithms for existing moving object detection algorithms. [0003] At present, the performance evaluation methods of moving object detection algorithms are mainly divi...
