PIL.Image转换成OpenCV格式
import cv2 from PIL import Image import numpy image = Image.open("plane.jpg") image.show() img = cv2.cvtColor(numpy.asarray(image),cv2.COLOR_RGB2BGR) cv2.imshow("OpenCV",img) cv2.waitKey()
OpenCV转换成PIL.Image格式
import cv2 from PIL import Image import numpy img = cv2.imread("plane.jpg") cv2.imshow("OpenCV",img) image = Image.fromarray(cv2.cvtColor(img,cv2.COLOR_BGR2RGB)) image.show() cv2.waitKey()
判断图像数据是否是OpenCV格式
isinstance(img, np.ndarray)
判断OpenCV版本是2还是3或4
import cv2 import imutils #若没有包使用 pip install imutils 安装 if imutils.is_cv2(): print("OpenCV2") if imutils.is_cv3(): print("OpenCV3") if imutils.is_cv4(): print("OpenCV4")
