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++

you probably need to show some code, images .

and have a look at findContours

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".
