python OpenCV jpeg compression in memory

Question

In OpenCV it is possible to save an image to disk with a certain jpeg compression. Is there also a way to do this in memory? Or should I write a function using cv2.ims

Answer 1

You can use imencode:

encode_param = [int(cv2.IMWRITE_JPEG_QUALITY), 90]
result, encimg = cv2.imencode('.jpg', img, encode_param)

(The default value for IMWRITE_JPEG_QUALITY is 95.)

You can decode it back with:

decimg = cv2.imdecode(encimg, 1)
