Optimal linear combination of RGB color model target recognition is proposed in order to improve the accuracy of target detection. This paper records the target and background on points of sampling of red, green, blue component val-ues, and then designs linear programming objective function and constraints. It makes out of the optimal solution of linear programming problem by using red, green, blue component statistics, and establishes the optimal linear combination of RGB color model. Under four kinds of light shooting conditions such as smooth light, side light, side backlight, backlight-ing...
