Abstract

The invention provides an infrared thermal image contour extraction method and device, belongs to the technical field of display, and can solve a problem that a conventional contour extraction method is very complex. The method comprises the steps: obtaining an infrared thermal image; determining a histogram according to the grey-scale map of the infrared image, determining the segmentation threshold value of the infrared image according to the histogram, and carrying out the contour extraction according to the segmentation threshold value.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a method and a device for extracting the outline of an infrared thermal image. Background technique [0002] As a basic feature of an image, the contour of an image often carries most of the information of an image and is often applied to deeper image applications. It has a wide range of applications in the fields of image recognition, image segmentation, image enhancement and image compression, and is also the basis of image processing. So this requires us to detect and extract the contour of an image. Contour extraction is considered a very important process in many intelligent vision systems. However, the methods for extracting the contours of infrared thermal images in the prior art are very complicated, so it is particularly important to need a simple and easy-to-operate contour recognition method. Contents of the invention [0003] The technical problem to...
