A kind of infrared image segmentation method, device and equipment based on difference information statistics

Abstract

The invention discloses an infrared image segmentation method, device, equipment and computer-readable storage medium based on difference information statistics, including: calculating the difference value of the four neighborhoods of each pixel of an infrared image; Difference value, according to the number of effective difference values ​​in the four neighborhoods of each pixel, the histogram index items corresponding to each pixel are accumulated to obtain a two-dimensional difference statistical histogram; the gray histogram of the infrared image and the two-dimensional difference statistical histogram are obtained by using the Otsu algorithm. Dimension difference statistical histogram for background segmentation; compare the background area of ​​the gray histogram with that of the two-dimensional difference statistical histogram; when the background area of ​​the two-dimensional difference statistical histogram is less than or equal to the background area of ​​the gray histogram, Obtain the maximum difference threshold; use the maximum difference threshold to segment the infrared image. The method, device, device and computer-readable storage medium provided by the present invention improve the image segmentation accuracy and have low computational complexity.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to an infrared image segmentation method, apparatus, device 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 infrared radiation distribution naturally emitted by the target surface into a visible image, so that the range of human visual perception extends 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, such as: precision guided weapons, foreground identification and tracking, early warning, artillery and missile fire control systems, medical diagnosis, non-destructive test...
