Revision history [back]

hi I'm new to opencv functions,so please excuse me if I'm asking a simple question. im trying to extract less feature from pics to use in lbp.facerecognizer() i want to put trained lbp model into my code so i need to reduce any thing like this

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,

error : no suitable constructor exists to convert from "int [256]" to "cv::_InputArray"

hi I'm new to opencv functions,so please excuse me if I'm asking a simple question. im trying to extract less feature from pics to use in lbp.facerecognizer() i want to put trained lbp model into my code so i need to reduce any thing like this

question 2: if i convert my images using below code,then trained a model using these images, is this right way or should add changes to lbp.facerecognizer function of opencv?

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,
