简要回顾了多小波变换理论及其在图像处理中的重要性质 ,分析了离散多小波变换时预滤波设计和边界处理问题。而后介绍了多小波变换在图像处理方面的应用。实验表明 ,多小波方法在图像数据压缩以及图像去噪等方面能够取得比单小波更好的效果。
The multiwavelet transform theory and its important properties in image processing are briefly reviewed. The pre-filter design and boundary processing problems in discrete multiwavelet transform are analyzed. Then introduce the application of multiwavelet transform in image processing. Experimental results show that the multiwavelet method can achieve better results than single wavelet in image data compression and image denoising.
