摘要
Abstract
Due to the low contrast of infrared image, image processing is always needed to be done during the infrared image acquisition. Image enhancement can be divided into frequency domain and spatial domain method. As the isolation feature of pure frequency domain or spatial domain method , it is likely to cause the loss of image information and limit the applicable occasions. Based on the above methods, this paper puts forward an image enhancement algorithm based on hierarchical processing. First the algorithm divides the original image into high frequency and low frequency through the frequency domain method. Then a gray stretch of high and low frequency images will be done through spatial domain method. At the time of enhancing image dynamic space, the details of image will be kept to the largest extent to obtain better image visual effect.关键词
