Infrared image segmentation method, device and equipment based on differential information statistics

Abstract

The invention discloses an infrared image segmentation method, device and equipment based on differential information statistics, and a computer readable storage medium. The method comprises the stepsof calculating differential values of four neighborhoods of each pixel of an infrared image; eliminating the invalid differential value of each pixel according to the current differential threshold,and accumulating the histogram index entries corresponding to each pixel according to the number of the valid differential values of the four neighborhoods of each pixel to obtain a two-dimensional differential statistical histogram; respectively carrying out background segmentation on the gray histogram and the two-dimensional differential statistical histogram of the infrared image by utilizingan Otsu algorithm; comparing the background area of the grayscale histogram with the background area of the two-dimensional differential statistical histogram; when the background area of the two-dimensional differential statistical histogram is smaller than or equal to the background area of the gray histogram, obtaining a maximum differential threshold; and segmenting the infrared image by usingthe maximum difference threshold. According to the method, the device, the equipment and the computer readable storage medium provided by the invention, the image segmentation precision is improved,and the calculation complexity is low.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an infrared image segmentation method, device, equipment and computer-readable storage medium based on differential information statistics. Background technique [0002] Infrared imaging technology, also known as thermal imaging technology, collects the thermal radiation information of the target scene through the detector, and converts the distribution of infrared radiation naturally emitted by the target surface into a visible image, extending the range of human visual perception from the traditional visible spectrum to the naked eye. less than the infrared radiation spectrum. At present, infrared imaging technology has been widely used in military detection and civilian monitoring and other fields, such as: precision guided weapons, prospect identification and tracking, early warning, artillery and missile fire control systems, medical diagnosis, non-destructi...
