I use opencv_traincascade.exe in 2.4.8 for Haar leraning. Do I really need a positive and a negative image to translate in the gray scale ?

What do you mean by " to translate in the gray scale " ?

Convert BMP file images from a color image to black and white.

You need positive and negative images to train the cascade. They can be color images.
