does any one has a uniform lbp c++ code with it's spatial histogram

edit

the idea behind the 'uniform' lbph is to compress the histogram from 256 items to 59 (faster/less memory) and at the same time achieving a bit more robustness against noise.

//
// Mat_<uchar> used here for convenient () operator indexing
//
uchar lbp(const Mat_<uchar> & img, int x, int y)
{
    // this is pretty much the same what you already got..
    uchar v = 0;
    uchar c = img(y,x);
    v += (img(y-1,x  ) > c) << 0;
    v += (img(y-1,x+1) > c) << 1;
    v += (img(y  ,x+1) > c) << 2;
    v += (img(y+1,x+1) > c) << 3;
    v += (img(y+1,x  ) > c) << 4;
    v += (img(y+1,x-1) > c) << 5;
    v += (img(y  ,x-1) > c) << 6;
    v += (img(y-1,x-1) > c) << 7;
    return v;
}

your code above tries to build an lbp image first, i'm going to skip that, and calculate the histogram directly from the (uniform) lbp values.

//
// you would usually apply this to small patches of an image and concatenate the histograms
//
void uniformLbpHist(const Mat & img_gray, Mat & hist)
{
    static uchar uniform[256] = { // hardcoded 8-neighbour case
        0,1,2,3,4,58,5,6,7,58,58,58,8,58,9,10,11,58,58,58,58,58,58,58,12,58,58,58,13,58,

    };
    // 59 bins, bin 58 is the noise/non-uniform slot:
    hist = Mat::zeros(59,1,CV_32F);

    Mat_<uchar>img(img_gray);

    for(int i=1;i<height-1;i++)
    {
        for(int j=1;j<width-1;j++)
        {
            uchar uv = lbp(img, j,i);
            hist[ uniform[uv] ] ++; // incr. the resp. histogram bin
