Problems solved by technology

The histogram equalization method improves the contrast of the image by stretching the gray area of ​​the histogram, but the enhancement effect is not obvious for different images, and the difference is large; the gray scale transformation method grays out the pixels of the original image one by one according to the mapping function. Degree value transformation, but different mapping functions are required for different scenes; the filter removes image noise by filtering the original image, but if the filter template i

Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0031] The infrared image reflects the spatial distribution of the invisible infrared radiation of the target and the background, and its radiance distribution is mainly determined by the temperature and emissivity of the observed scene, so the infrared image approximately reflects the temperature difference or radiation difference of the scene. Image enhancement refers to emphasizing or highlighting certain features of an image, such as edges, contours, contrast, etc., for easy observation or further analysis and processing. Image enhancement does not mean that the origin...

Abstract

The invention relates to an infrared image enhancement method and device, computer equipment and a storage medium. The method comprises the steps of obtaining an original infrared image; Segmenting the original infrared image to obtain a basic layer image and a detail layer image; Respectively carrying out image enhancement on the basic layer image and the detail layer image; And fusing the enhanced base layer image and the detail layer image to obtain a detail enhanced image. According to the infrared image enhancement method, the details of the infrared image are obviously enhanced, the detail information of the infrared image is prevented from being lost, and the infrared image enhancement method can adapt to infrared images of most scenes.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an infrared image enhancement method, device, computer equipment and storage medium. Background technique [0002] In nature, electromagnetic waves with a wavelength between 2.0-1000 μm are called thermal infrared rays (also called thermal radiation). As long as the temperature of an object is above thermodynamic zero (-273°C), it can emit infrared light. Since the human eye cannot recognize infrared light, a special device must be used to visualize the infrared signal, that is, an infrared imaging system. A typical infrared imaging system consists of an optical system, an infrared detector, and an electronic processing system. The main function of the optical system is to image the thermal radiation of the target object on the photosensitive surface of the infrared detector. The detector converts the infrared light signal into a digital signal, and finally co...
