The image interpolation algorithm can calculate the pels' value of the new image on the coordinates of the original image and the new image. 图像空间变换按照实际需要规定了变换后图像形状,图像插值算法依据图像空间变换前后的坐标计算得到变换后的图像像素值。
The fuzzy impulse noise detector using median value and neighbourhood information detects impulse noise.The impulse noise canceller uses minimum-maximum estimate method. 模糊脉冲噪声检测器用窗口内的中值与邻近像素信息来检测脉冲噪声,而脉冲消除器用最小最大值算法来计算噪声像素的估计值。
