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()

        grayp1 = int(gray[i,j+5])

        if newp > 255:
            newp = 255
        if newp <0:
            newp =0
        dst[i,j] = newp
