Firstly, the method decomposes the coke micrograph with WBCT for multi-scale and multi-direction, and extracts the statistical features from each sub-band.

首先，运用WBCT对图像进行多尺度多方向分解，提取出各子频带的统计特征量；

For visualization and contrast of IR images are weak, this paper proposed an algorithm for infrared and visible images fusion using wavelet-based contourlet transform (WBCT) and region energy.

针对红外图像可视化程度弱、对比度低的问题，提出一种基于轮廓小波变换和区域能量的红外与可见光图像融合算法。
