直接贴程序:


import cv2
import numpy as np
import os,sys,time,copy
import imutils
print("")

image = cv2.imread("lena.jpg")

for J,jn in enumerate(range(10,500,10)):
    resized = imutils.resize(image, width=jn)# 高度自动调整
    cv2.imshow("cap", resized)
    cv2.waitKey(3)


translated = imutils.translate(image, x=50, y=-30)  # 向右50像素，向上30像素

rotated = imutils.rotate(image, angle=45)  # 顺时针旋转45度

for J,jn in enumerate(range(-500,500,100)):
    for K,kn in enumerate(range(-500,500,100)):
        translated = imutils.translate(image, x=jn, y=kn)
        cv2.imshow("cap", translated)
        cv2.waitKey(3)
        
for J,jn in enumerate(range(-500,500,100)):
    for K,kn in enumerate(range(-500,500,100)):
        translated = imutils.translate(image, x=kn, y=jn)
        cv2.imshow("cap", translated)
        cv2.waitKey(3)
        
while True:
    for I,n in enumerate(range(1,365+45,1)):
        #print(f"In{I+1}:= {IoCardGet(n)}")
        
        rotated_border = imutils.rotate_bound(image, n)  # 避免裁剪
        cv2.imshow("cap", rotated_border)
        cv2.waitKey(5)

input()


if imutils.is_cv2():
    print("OpenCV 2.x")
elif imutils.is_cv3():
    print("OpenCV 3.x")

cv2.destroyAllWindows()
input()

哈哈哈是不是挺无聊的用于手上只有一张图又要测试匹配性能的时候就把派上用场了

imutils 是依赖opencv的
