python生成图像公章,python利用opencv实现印章的提取

抽空写了下，怕找不到了，做个备份，直接上代码，嗯，自己能看懂就喜欢这种感觉：

#coding:utf-8

import cv2

import numpy as np

#加载图片

image = cv2.imread('img\111.jpg')

#统一处理图片大小

img_w = 650 if image.shape[1] > 600 else 400

image = size(image, (img_w,int(img_w*image.shape[0]/image.shape[1])), interpolation=cv2.IMREAD_COLOR)

impng=cv2.py(), cv2.COLOR_RGB2RGBA)

# image = cv2.cvtColor(image, cv2.COLOR_RGBA2BGR)

#image = cv2.imread('img\public-2004-16-a7912dbd-72b0-4d96-9d65-70abc21940d5.png')

hue_image = cv2.cvtColor(image, cv2.COLOR_BGR2HSV)

low_range = np.array([130, 43, 46])

high_range = np.array([180, 255, 255])

th = cv2.inRange(hue_image, low_range, high_range)

element = StructuringElement(cv2.MORPH_RECT, (1, 1))</
