I’m trying to convert image from PIL
to OpenCV
format. I’m using OpenCV 2.4.3
.
here is what I’ve attempted till now.
>>> from PIL import Image >>> import cv2 as cv >>> pimg = Image.open('D:\traffic.jpg') #PIL Image >>> cimg = cv.cv.CreateImageHeader(pimg.size,cv.IPL_DEPTH_8U,3) #CV Image >>> cv.cv.SetData(cimg,pimg.tostring()) >>> cv.cv.NamedWindow('cimg') >>> cv.cv.ShowImage('cimg',cimg) >>> cv.cv.WaitKey()
But I think the image is not getting converted to CV format. The Window shows me a large brown image.
Where am I going wrong in Converting image from PIL
to CV
format?
Also , why do i need to type cv.cv
to access functions?

use this:
pil_image = PIL.Image.open('Image.jpg').convert('RGB') open_cv_image = numpy.array(pil_image) # Convert RGB to BGR open_cv_image = open_cv_image[:, :, ::-1].copy()
