怎样用c语言将rgb转成hsv再进行肤色检测？

Question

找到的相关代码，运行后点击窗口的“肤色检测”按钮会出现闪退，想了好久不知道问题在哪

函数代码

//显示肤色BMP图像
void ShowSkinBMPImage(char *Image, int *sImage, int wImage, int hImage, int xPos, int yPos)
{
int i,j;
int R,G,B;

for (i=0; i<hImage; i++){
    for (j=0; j<wImage; j++){
        R = G = B = 0;

        if (SkinImage[i*wImage+j] == 1){
            //获取像素rgb
            R = (BYTE) Image[i*3*wImage+j*3]; 
            G = (BYTE) Image[i*3*wImage+j*3+1]; 
            B = (BYTE) Image[i*3*wImage+j*3+2]; 
        }            
        SetPixel(hWinDC, j+xPos, i+yPos, RGB(R,G,B));//将指定坐标处的像素设为指定的颜色
    }
}

}

//HSV颜色空间肤色检测
void SkindetectionHSV(char *srcImage, int *sImage, int width, int height)
{
int i, j;
float R,G,B;
float max = 0,min = 0;
float *h=0,*s=0,*v=0;

for (j = 0; j < height; j++){
    for (i = 0; i < width; i++){
        sImage[i*width+j] = 0;
    }
}

for(j = 0; j < height; j++){
    for(i = 0; i < width; i++){
        R = (BYTE) srcImage[i*3*width+j*3]; 
        G = (BYTE) srcImage[i*3*width+j*3+1]; 
        B = (BYTE) srcImage[i*3*width+j*3+2]; 

        //归一化
        R=R/255;
        G=G/255;
        B=B/255;

        //rgb转换为hsv
        max = max(R,G,B);
        min = min(R,G,B);
        if(max == min)
            *h = 0;
        else if(max == R && G>=B)
            *h = 60*((G-B)/(max-min));
        else if(max == R && G<B)
            *h = 60*((G-B)/(max-min)) + 360;
        else if(max == G)
            *h = 60*((B-R)/(max-min)) + 120;
        else if(max == B)
            *h = 60*((R-G)/(max-min)) + 240;
        /*if(max == 0)
            *s = 0;
        else
            *s = 1 - (min/max);              
        *v = max;*/
        if ((*h >= 2) && (*h <= 13)){
            sImage[i*width+j] = 1;
        }
    }
}

}

调用代码
case SkinPhoto://肤色检测
SkindetectionHSV(Image, SkinImage, ImageWidth, ImageHeight);
ShowSkinBMPImage(Image, SkinImage, ImageWidth, ImageHeight, 600, 0);
break;

双循环给sImage数组赋值中i和j反了
