中文说明：
Curvelet变换是由一种特殊的滤波过程和多尺度脊波变换组合而成：本程序对彩色图像进行了curvelet变换从而实现图像去噪的效果。首先对图像进行子带分解；然后对不同尺度的子带图像采用不同大小的分块；最后对每个分块进行Ridgelet分析。
English Description：
Curvelet transform is a combination of a special filtering process and multi-scale ridgelet transform: This program performs curvelet transform on color image to achieve the effect of image denoising. Firstly, the image is decomposed into subbands; secondly, the subband images of different scales are divided into blocks of different sizes; finally, ridgelet analysis is performed on each block.
