matlab 下经典的利用wavedec2,appcoef2,detcoef2对图像进行分解提取高低频系数完成图像压缩和重构的源程序.

用wavedec2()函数对b1,b2两幅图像进行小波分解, 采用’haar’小波, 尝试着分解到第二或第三级 融合两幅图像。-With wavedec2 () function b1, b2 two images using wavelet decomposition, using haar wavelet, trying to break into the second or third grade fusion of two images.

小波阈值消噪程序，能量谱分析，希望能帮助大家-Wavelet threshold denoising procedures, energy spectrum analysis, we hope to help
