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.
