Target saliency detection method for improving anti-interference performance

Abstract

The invention provides a target saliency detection method for improving anti-interference performance, belongs to the technical field of image target detection, comprises a target saliency detection method based on gray scarcity, solves the problem of inaccurate detection caused by a small target, and also overcomes gradient interference. The method further comprises a target saliency detection method combining gray scale stability and gray scale scarcity so as to solve the saliency detection problem of multiple small targets and overcome small clutter type and gradual change type background interference. The target saliency detection method comprises the following steps: quantizing a grayscale image in a grading manner to obtain a quantized image; the gray value with the small statistical frequency is endowed with a larger significant value; and superposing the quantized images to form a gray scale scarcity saliency map. In addition, performing equal-interval threshold segmentation on the grayscale image to obtain an MSER region; carrying out superposition on the screened MSER regions to form a saliency map; and fusing the two saliency images. According to the method, the accuracy of target detection and recognition is improved.

Description

technical field [0001] The invention belongs to the technical field of visible light image target detection, and relates to a target saliency detection method. Background technique [0002] In the terminal guidance technology, the target detection and identification technology is the key technology for the initialization of the non-human guided target at the end of the loop, which directly affects the effect of the terminal guidance. [0003] For general targets, many very comprehensive datasets (such as Pascal VOC, COCO) can be provided for neural network training. [0004] For the TV seeker to detect the position of military vehicles in the field, it is difficult to obtain image data sets of military vehicle targets in the field, especially the data sets of military vehicle targets seen by the seeker in the terminal guidance and control scene are even more difficult to obtain. The reason is: due to the sensitivity of military vehicles, the image of the target cannot be di...
