关键词Infrared Imaging Multi-scale Nonlinear Amplification Image Enhancement
摘要Due to the restriction of infrared imaging component and the radiation of atmosphere, Infrared images are discontented with image contrast, blurry, large yawp. Aimed on these problems, A multi-scale image enhancement algorithm is proposed. The main principle is as follows: firstly, On the basis of the multi-scale image decomposition, We use an edge-preserving spatial filter that instead of the Gaussion filter proposed in the original version, adjust the scale-dependent factor With a weighted information. Secondly, Contrast is equalized by applying nonlinear amplification. Thirdly, Subband image is the weighted sum of sampled subband image and subsampled then up sampled subband image by a factor of two. Finally, Image reconstruction was applied. Experiment results show that the proposed method can enhance the original infrared image effectively and improve the contrast, moreover, it also can reserve the details and edges of the image well.
