how to use imread?
about the function - imread Second argument is a flag which specifies the way image should be read. cv2.IMREAD_COLOR : Loads a color image. Any transparency of image will be neglected. It is the default flag. cv2.IMREAD_UNCHANGED : Loads image as such including alpha channel
what does transparency mean?
what kind of image have alpha channel,can i add alpha channel into a image using openCV, and how to write out?
can you guys give some examples? thanks a lot
alpha channel means nothing in image processing. It's agraphics technic. if you want to use this alpha chanel you can use add weighted function.
