Abstract

The invention belongs to the technical field of image processing, and more particularly relates to a GRHP based unmanned plane infrared image detail enhancement method. The method comprises the steps of sequentially performing denoising, filtering, subtraction, enhancing and synthesizing on an original image; performing adaptive threshold value histogram projection on synthesized image; and obtaining an output image. The method has the beneficial effects that the running efficiency is high, and an infrared video can be processed in real time when the unmanned plane has low hardware configuration; due to introduction of Gaussian constraint filtering, manual work effect is prohibited effectively, and the detail enhancement effect of the method on the infrared image is ensured; due to introduction of an adaptive detail enhancement coefficient, transient state continuity of the method in video processing is solved, and adaptation of the method to a scene is improved; and due to introduction of the adaptive threshold value histogram projection, image noise is further prohibited, furthermore, image contrast is effectively improved, and the detail enhancement capability of the method is improved.

Description

Technical field [0001] The invention belongs to the technical field of image processing, and specifically relates to a GRHP-based method for enhancing the details of drone infrared images. Background technique [0002] In recent years, infrared imaging technology has become more and more widely used in the fields of public security, fire protection, military, medicine, electric power industry, etc. However, due to the performance limitations of detectors, infrared images often have low contrast, unobvious details, and poor visual effects. The performance is particularly obvious in man-machine reconnaissance applications. In order to improve image interpretation and solve the problem of blurring of image targets and scene details, infrared image detail enhancement technology (Digital Detail Enhancement, DDE) has received widespread attention. The ability to detect and recognize small objects can be improved by enhancing the contrast of the fine structures (such as edges, contours...
