transparent img

[Alan29535]

If my image has a transparent or dark background, is there any way to allow the script to identify this image?
I have tried to change the background color by adding values to all pixels, but it still does not work as the color image converts to grayscale, then shows an error: I computed that background is 'dark' which is unacceptable to me.

Can you post the image?

Thanks for the image. It is very helpful.

You may try https://superuser.com/questions/1194468/invert-colors-with-imagemagick and invert the colors of this image. Run the script again and see if you get you helpful results.

Unfortunately, I am short of time these days so I may not be able to look at this issue in detail anytime soon.
