opencv图像处理浮雕效果

浮雕效果是将俩个像素差值加上某一个固定的像素值。

import cv2 import numpy as np import random import math img0 = cv2.imread(r"C:\Users\lenovo\Desktop\python\python_vision\image.jpg",1) imgInfo = img0.shape height = imgInfo[0] weight = imgInfo[1] # 转换灰度图像 2.高斯滤波 gray = cv2.cvtColor(img0,cv2.COLOR_RGB2GRAY) dst = np.zeros((height,weight,1),np.uint8) for i in range(0,height): for j in range(0,weight-5): grayp0 = int(gray[i,j]) grayp1 = int(gray[i,j+5]) newp = grayp0-grayp1 +100 if newp > 255: newp = 255 if newp <0: newp =0 dst[i,j] = newp cv2.imshow("dst",dst) cv2.waitKey()

公式： 浮雕效果展示： 核心代码展示：

for i in range(0,height): for j in range(0,weight-5): grayp0 = int(gray[i,j]) grayp1 = int(gray[i,j+5]) newp = grayp0-grayp1 +100 if newp > 255: newp = 255 if newp <0: newp =0 dst[i,j] = newp
