Infrared imaging cirrus cloud detection method and device based on visual saliency

Abstract

The invention relates to an infrared imaging cirrus cloud detection method and device based on visual saliency and a computer readable storage medium. The method comprises the following steps of inputting a to-be-detected infrared image; detecting the infrared image by using a frequency modulation saliency detection method to obtain a saliency feature map; performing gamma change contrast enhancement on the saliency feature map to obtain a contrast enhancement map; performing Laplace high-lift filtering on the contrast enhancement image to obtain an edge enhancement image; carrying out regiongrowth processing on the saliency characteristic graph, and obtaining a region growth graph by taking adopted seed points as points of which the gray values are higher than 99% in the edge enhancementgraph; contour extraction being carried out on the region growth map to obtain a contour binary image; and performing target area labeling on the infrared image according to the contour binary image,and outputting a cirrus cloud detection result image. According to the method, the detection area is more accurate, algorithm complexity is low, the real-time performance is good, and the requirementon imaging equipment is not high.

Description

technical field [0001] The invention relates to the field of target detection in remote sensing and infrared image processing, in particular to a visual saliency-based infrared imaging cirrus detection method, device and computer-readable storage medium. Background technique [0002] Infrared imaging has the advantages of long range, high concealment, good anti-interference, not affected by obstacles such as smoke, and can work around the clock. Therefore, it is widely used in military fields such as security monitoring, reconnaissance, navigation, and homing guidance. In military early warning, missile interception and other systems, target detection, as the front-end processing link in the homing guidance system, is the most critical and core component of precision guidance. However, the farther the distance is, the smaller the target imaging area is, the worse the image quality is, and the more difficult it is to detect the target. In remote sensing infrared imaging sate...
