When I convert my image to a binary image, this part of light reflection becomes white, and I need to get the exact contour of the character . How I could solve this...

PS: I use opencv c++

thanks

If the area is not completely white or black, converting the image from RGB to HSV or HSL and then ignoring the Saturation or Lightness channels might be a solution, because now the image is invariant to "whitening".
