| 摘 要： | 根据小波变换图像检测的有关原理，实现了用相邻两个量化方向上像素模值加权平均的方法求取边界图像，并结合算例对基于多尺度边度图像恢复原图像的问题进行了讨论，以此为基础配合去噪处理可有效提高字图像的输出质量。

| Abstract: | According to the theory of image detection with wavelet transform,the algrithm for edge image is given,which is weighted average method about modulus at pixels aligned at two adjacent quantized direction,and problem on image restoration with multiscale edge image is discussed by example.Based on these,output quality of word image is improved effectively with denoising. |
