i add below code to LBPH::train(InputArrayOfArrays _in_src, InputArray _in_labels, bool preserveData) after produced the mat lbp_image (in opencv source) static int uniform[256] = // for exactly 8 bits / neighbours ! { 0,1,2,3,4,58,5,6,7,58,58,58,8,58,9,10,11,58,58,58,58,58,58,58,12,58,58,58,13,58,14,15,16,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,17,58,58,58,58,58,58,58,18,58,58,58,19,58,20,21,22,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,23,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,24,58,58,58,58,58,58,58,25,58,58,58,26,58,27,28,29,30,58,31,58,58,58,32,58,58,58,58,58,58,58,33,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,34,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,35,36,37,58,38,58,58,58,39,58,58,58,58,58,58,58,40,58,58,58,58,58,58,58,58,58,58,58,58,58,58,58,41,42,43,58,44,58,58,58,45,58,58,58,58,58,58,58,46,47,48,58,49,58,58,58,50,51,52,58,53,54,55,56,57}; Mat out; Mat lookup(1,256,CV_32S, uniform); // make a Mat from it LUT(lbp_image,lookup,lbp_image); then also the number of histogram bins from 256 to 59 like below : Mat p = spatial_histogram( lbp_image, /* lbp_image */ static_cast(59), /* number of possible patterns */ _grid_x, /* grid size x */ _grid_y, /* grid size y */ true); but i got this error : assertion failed : (lutcn == cn || lutcn == 1) && lut.total() == 256 && lut.isContinuous() && (src.depth() == CV_8U || src.depth() == CV_8S) in function LUT i know that problem is in : src.depth() == CV_8U || src.depth() == CV_8S) please help me in detail that what changes are need, im a begginer in opencv
