直接上源码：
void testApp::ofSkinDetector(unsigned char* Pointer, ofImage& image, int CAMERA_WIDTH, int CAMERA_HEIGHT)
{
int len = CAMERA_WIDTH * CAMERA_HEIGHT * 3;
unsigned char* SkinP= new unsigned char[len];
for (int Y = 0; Y < CAMERA_HEIGHT; Y++)
{
for (int X = 0; X < CAMERA_WIDTH; X++)
{
unsigned char Red = Pointer[CAMERA_WIDTH * Y * 3 + X * 3];
unsigned char Green = Pointer[CAMERA_WIDTH * Y * 3 + X * 3 + 1];
unsigned char Blue = Pointer[CAMERA_WIDTH * Y * 3 + X * 3 + 2];
unsigned char Max = 0, Min = 0;
if (Red > 95 && Green > 40 && Blue > 20 && Red > Blue && Red > Green && abs(Red - Green) > 15)
{
if (Blue >= Green)
{
Max = Blue;
Min = Green;
}
else
{
Max = Green;
Min = Blue;
}
if (Red > Max)
Max = Red;
else if (Red < Min)
Min = Red;
if (Max - Min > 15)
{
SkinP[CAMERA_WIDTH * Y * 3 + X * 3] = 255;
SkinP[CAMERA_WIDTH * Y * 3 + X * 3 + 1] = 255;
SkinP[CAMERA_WIDTH * Y * 3 + X * 3 + 2] = 255;
}
}
}
}
image.setFromPixels(SkinP, CAMERA_WIDTH, CAMERA_HEIGHT, OF_IMAGE_COLOR);
delete SkinP;
SkinP = NULL;
}
