python实现对彩色图像red.jpg进行自适应中值滤波，滤波器大小为7×7

好的，以下是Python实现对彩色图像进行自适应中值滤波的代码，滤波器大小为7x7：

import cv2

# 读取图像
img = cv2.imread('red.jpg')

# 自适应中值滤波
def AdaptiveMedianFilter(img, maxWindowSize):
    rows, cols, channels = img.shape
    output = img.copy()
    for i in range(rows):
        for j in range(cols):
            for c in range(channels):
                windowSize = 3
                while windowSize <= maxWindowSize:
                    # 计算当前窗口的左上角和右下角坐标
                    left = max(j - windowSize, 0)
                    top = max(i - windowSize, 0)
                    right = min(j + windowSize, cols - 1)
                    bottom = min(i + windowSize, rows - 1)
                    # 计算窗口内像素的中值
                    window = img[top:bottom+1, left:right+1, c]
                    median = cv2.medianBlur(window, 1)[windowSize-2, windowSize-2]
                    # 判断是否需要继续扩大窗口
                    if img[i, j, c] < median:
                        windowSize += 2
                        if windowSize > maxWindowSize:
                            output[i, j, c] = median
                    else:
                        output[i, j, c] = img[i, j, c]
                        break
                else:
                    output[i, j, c] = median
    return output

output = AdaptiveMedianFilter(img, maxWindowSize=7)

# 显示原图和处理后的图像
cv2.imshow('Original Image', img)
cv2.imshow('Adaptive Median Filter', output)
cv2.waitKey(0)
cv2.destroyAllWindows()

注意：在运行代码之前，请确保已经安装了OpenCV库。
