Other AbstractThe invention relates to a background clutter measurement method based on edge structures, comprising the following steps: segmenting a background image into cells of the same size as a target image; establishing a similarity measure between the target image and cell background clutter images in an image structure feature space; establishing edge structure feature descriptions of the target image and the cell background clutter images through a gradient histogram method, and selecting a Bhattacharyya coefficient to calculate the similarity measure between the image edge structures; and weighting the structure similarity measure between the target image and each cell background clutter image as the clutter measure of the cell background image based on the edge structure similarity measure between the target image and the cell background clutter image, and taking the average clutter measure of all the cell background images as the clutter measure of the whole background image. The method fully embodies the fact that human eye vision mainly focuses on the object structure in target identification, and improves the accuracy of imaging system field performance prediction and evaluation.
