The invention discloses a high dynamic infrared image enhancement method based on multi-scale processing. Firstly, a weight least square filter is applied to carry out edge preserving type image multi-scale hierarchical operation on an original image, then the respective obtained multi-layer detail image and residual fuzzy image are processed, thus the detail is amplified appropriately, a residual layer is compressed, finally a plurality of detail layers and the residual layer are combined, and a low dynamic range image for display is obtained. According to the method, infrared image details can be reserved well, and halo and gradient reversal phenomena in a synthetic image caused by a detail separation operation are avoided or weakened at the same time.

The invention discloses a large-dynamic-range infrared image display and detail enhancement method based on a guiding filter. According to the method, firstly, the guiding filter is used for carrying out edge reserved smoothing filtering processing on an original large-dynamic-range infrared image to obtain base layer image information with blurry details, the difference between a base layer image and the original image is obtained to obtain image detail layer information, self-adaption enhancement processing is carried out on a detail layer image, dynamic range compressing is carried out on the base layer image, finally, the processed detail layer image and the processed base layer image are combined, an overflow value is removed, and a low-dynamic-range image finally used for being displayed is obtained. According to the method, image data can be compressed, the image contrast can be effectively improved at the same time, image details are enhanced, and the visual effect of the images ...
