ubuntu 12.04 - Error in trying Face recognition demo in opencv -


i using ubuntu 12.04, , have installed opencv 2.4 (actually, installed ros, opencv gets installed it) trying run demo , getting error:

usama@ubuntu:~/desktop/opencv/advanced/face recognition$ g++ `pkg-config opencv --cflags` face_recog.cpp -o face_recog `pkg-config opencv --libs` face_recog.cpp: in function ‘int main(int, const char**)’: face_recog.cpp:119:30: error: ‘class cv::facerecognizer’ has no member named ‘getmat’ face_recog.cpp:121:20: error: ‘class cv::facerecognizer’ has no member named ‘getmat’ facerecog.cpp:123:23: error: ‘class cv::facerecognizer’ has no member named ‘getmat’

any idea, how can rid of error ? should upgrade opencv new version ?

only since opencv 2.4.2 can use cv::algorithm functions getmat(...) cv::facerecognizer. cv::facerecognizer in (the official) opencv 2.4.0 , opencv 2.4.1 wasn't based on cv::algorithm, examples opencv 2.4.2 documentation won't work opencv 2.4.0/2.4.1 release.

so yes, suggest updating opencv 2.4.2. it's been officially released days ago, see new user page @ http://www.opencv.org.

if can't update opencv, either try opencv 2.4.0/2.4.1 compatible demo:

or give libfacerec try, has same interface opencv 2.4.2 implementation:

it depends on opencv version. if using opencv 2.3, try version 0.04 of libfacerec. however, if using opencv 2.4.2 , have problems, please issue bug on official opencv bugtracker:

in case didn't notice. can ask opencv related questions on:

where lot of opencv experts are.

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
