The Infrared Image Enhancement Approach Based on Directionlet Transform
The chapter proposed a new multi-scale infrared image enhancement method based on directionlet transform, using directionlet transform to decompose the image’s frequency domain, and the establishment of a multi-directional anisotropic filtration has enhanced the infrared image. The experiment has showed that the method has achieved better result in the aspects of visual effect and objective evaluation than the general transform domain enhancement method.
