python 两幅图片融合成一张图片

示例代码：

# -*- coding:utf-8 -*-
from skimage import io
import cv2
from PIL import Image,ImageDraw,ImageFont

def blend_two_images(img_file1,img_file2,img_file3,text, left, top, text_color=(255, 0, 0), text_size=13):
	img1 = Image.open(img_file1)
	#print(img1.shape) 
	img1 = img1.convert(RGBA)
	img2 = Image.open(img_file2)
	img2 = img2.convert(RGBA)
	# 尺寸调整，如果两幅图像大小不一样，需要 resize
	#img1 = img1.resize((224, 224))
	#img2 = img2.resize((224, 224))
	img = Image.blend(img1, img2, 0.5)
	# 创建一个可以在给定图像上绘图的对象
	draw = ImageDraw.Draw(img)
	# 字体的格式 Centos中都在字体可用命令 fc-list 查询，选中一个合适的字体就行
	fontStyle = ImageFont.truetype("/usr/share/fonts/dejavu/DejaVuSerif-Bold.ttf", text_size, encoding="utf-8")
	# 绘制文本
	draw.text((left, top), text, text_color, font=fontStyle)
	img.show()
	img.save(img_file3)

if __name__=="__main__":
	img_file1=r"./ori.jpg"
	img_file2=r"./heatmap2.jpg"
	img_file3=r"./test3.png"
	blend_two_images(img_file1,img_file2,img_file3,"test", 50, 100, text_color=(255, 0, 0), text_size=50)
