python base64 编解码,转换成Opencv,PIL.Image图片格式

二进制打开图片文件,base64编解码,转成Opencv格式:

# coding: utf-8
import base64
import numpy as np
import cv2

img_file = open(r'00.JPG','rb')   # 二进制打开图片文件
img_b64encode = base64.b64encode(img_file.read())  # base64编码
img_file.close()  # 文件关闭
img_b64decode = base64.b64decode(img_b64encode)  # base64解码

img_array = np.fromstring(img_b64decode,np.uint8) # 转换np序列
img=cv2.imdecode(img_array,cv2.COLOR_BGR2RGB)  # 转换Opencv格式

cv2.imshow("img",img)
cv2.waitKey()


二进制打开图片文件,base64编解码,转成PIL.Image格式:

# coding: utf-8
# python base64 编解码,转换成Opencv,PIL.Image图片格式
import base64
import io
from PIL import Image

img_file = open(r'/home/dcrmg/work/medi_ocr_v1.2/img/00.JPG','rb')   # 二进制打开图片文件
img_b64encode = base64.b64encode(img_file.read())  # base64编码
img_file.close()  # 文件关闭
img_b64decode = base64.b64decode(img_b64encode)  # base64解码

image = io.BytesIO(img_b64decode)
img = Image.open(image)
img.show()
