+A blc channel **/pinobo.coord** is created with the center of gravity of the color <x uchar><y uchar>.
+The thresholds for the color in YUV format is: u for U min, U for U max, v for V min and V for V max.
+You can use the parameter '-p/color' to have a blc_channel '/color' where you can dynamicaly change the threholds of the color.
+**/object** is the image of the object where each pixel is set to 255 if the color is in the selected range. 
+It is used for debug.
