- 一幅原始图像,在获取和传输过程中,会受到各种噪声的干扰,使图像退化,质量下降. 退化会引起图像模糊,特征淹没,对分析图像不利.为了抑制噪声改善图像质量进行的处理称为图像平滑或去噪.利用高斯函数得到了图像平滑去除随机噪声中使用的平滑模板的一个较普遍的公式。该公式为图像平滑去除噪声提供了多种模板选择。针对不同的图像噪声水平，选取不同的模板，才能达到去除噪声的最理想的效果。文中给出了图像平滑的实现算法,显示结果验证了上述方法和结论。-Any picture would be affected by a

- opencv实现傅里叶变换,傅立叶变换是把图像从空间域转化到频率域的变换。空间域：一般的情况下，空间域的图像是f（x，y）=灰度级（0-255），形象一点就是一个二维矩阵，每个坐标对应一个颜色值。频率域：频率：对于图像来说可以指图像颜色值的梯度，即灰度级的变化速度，幅度：可以简单的理解为是频率的权，即该频率所占的比例：能量=幅度（可能不太准确），变换结果为F（u，v），F代表幅度值，u代表x方向的频率，v代表y方向的频率(Fu Liye transform is the transformati
