python Opencv将图片转为字符画
做了个Python的小练习,网上有人是利用PIL中的Image来实现的,觉得Opencv库挺方便的,于是利用Opencv库来实现了一下,代码如下:
# -*- coding: utf-8 -*-

# 实现将图片转为字符画
import cv2
ascii_char = list("$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/\|()1{}[]?-_+~<>i!lI;:,\"^`'. ")
# 将灰度值转为字符
def get_char(gray_number):
length = len(ascii_char)
unit = (256.0 + 1)/length
return ascii_char[int(gray_number/unit)]
if __name__ == '__main__':
image1 = cv2.imread('8.jpg')
image = cv2.resize(image1,(85,110))
gray = cv2.cvtColor(image,cv2.COLOR_BGR2GRAY)
txt = ""
for i in range(image.shape[0]):
for j in range(image.shape[1]):
# 对打开的图片的每个坐标的灰度值做判断,
# 用get_char()获取该颜色灰度值对应的字符,然后拼接成字符串txt
txt += get_char(gray[i,j])
txt += '\n'
print txt
#字符画输出到文件中
f = open('output.txt','w')
f.write(txt)
结果是:
原图片:
结果:
