Abstract

The invention relates to a weak and small moving target detection method based on superpixel adjacent frame feature comparison. The method comprises the following steps of: 1, performing super-pixel segmentation on a target frame image by using an SLIC (simple linear iterative clustering) algorithm; 2, generating a graph theory model according to the adjacency relation of the superpixels, designing superpixel features, calculating feature differences among the superpixels, taking the feature differences as edge values in the graph theory model, and realizing potential target extraction by utilizing a graph segmentation algorithm; and 3, performing adjacent frame color feature comparison on the potential target area, and if the color feature difference exceeds a set threshold, marking the potential target area as a moving target. According to the method, inter-frame search is avoided, and the efficiency of detecting the weak and small moving target is improved.

Description

technical field [0001] The invention relates to a weak and small moving target detection method based on superpixel adjacent frame feature comparison, and belongs to the technical field of image processing. Background technique [0002] Weak and small moving target detection is an important research topic in the field of image processing and machine vision. Objects of interest and motion in image sequences or videos are distinguished and extracted from the background. In recent years, with the development of drones, the demand for security monitoring of drones has gradually increased, so how to realize weak and small moving target detection has become one of the research hotspots. [0003] Zhu Xuan ("Moving Target Detection Based on Continuity Constrained Background Model Subtraction", Computer Science, 2019, 06, 311-315) proposed a low-rank decomposition background update model with temporal continuity constraints, and applied it to the background model Subtractive video ...
