小波逆变换的源代码-inverse wavelet transform source code

小波DWT变换，一般大家是用matlab实现，但是这段程序是用c语言编写。-wavelet dwt

对输入图像进行预处理后提取目标轮廓，经过归一化处理得到目标形 状的平移、尺度不变的链状表达，再通过小波变换进行多尺度分析；引入Zernike 矩，利用Zernike 矩的特性，实现小波表达的旋转不变性，解决了小波变换对起始点的依赖。-right to import images from pretreatment profile targets, after processing to be a target shape translation, The scale-invariant chain expression, and through the wavelet transform multi-scale analysis; introduction Zernike moment, use Zernike moments, wavelet achieve expression of rotation invariance, solve the wavelet transform the dependence of the threshold.
