摘要
分析了小波变换进行低分辨率快速图像轮廓重构和局部区域精确重构的算法。在这种算法中,滤波器与小波有关,从而可由反投影得到各种小波图像。通过小波多尺度分析和小波系数控制,提出一种简单算法进行图像增强和噪声去除。与标准的算法相比,该算法提高了重建速度和图像精度。
An algorithm that uses wavelet transform to quickly reconstruct image profile in low-resolution and precisely reconstruct local image is analyzed. In this algorithm the filter is related to wavelet and thus various wavelet images can be obtained by back-projection. A simple algorithm which is used to enhance image and eliminate noise is proposed through multi-dimensioned wavelet analysis and wavelet coefficient control. Compared with the standard algorithm, the algorithm improves the reconstruction speed and image accuracy.
