imutils opencv-python 的一些操作

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
