python代码:
import cv2 as cv
import numpy as np
def laplaian_demo(pyramid_images):
level = len(pyramid_images)
for i in range(level-1, -1, -1):
if (i-1) < 0:
h, w = src.shape[:2]
expand = cv.pyrUp(pyramid_images[i], dstsize=(w, h))
lpls = cv.subtract(src, expand) + 127
cv.imshow("lpls_" + str(i), lpls)
else:
h, w = pyramid_images[i-1].shape[:2]
expand = cv.pyrUp(pyramid_images[i], dstsize=(w, h))
lpls = cv.subtract(pyramid_images[i-1], expand) + 127
cv.imshow("lpls_"+str(i), lpls)
def pyramid_up(image, level=3):
temp = image.copy()
# cv.imshow("input", image)
pyramid_images = []
for i in range(level):
dst = cv.pyrDown(temp)
pyramid_images.append(dst)
# cv.imshow("pyramid_up_" + str(i), dst)
