php - .htaccess Rewrite Rules conflict -

-

i have .htaccess file written follows:

rewriteengine on  rewriterule ^/?([^/.]+)$ display.php?category=$1 [b,l]  rewriterule ^gallery/([^/.]+)/?$ gallery.php?category=$1 [l] rewriterule ^([-_\+a-za-z0-9,]+)$ displayitem.php?item=$1 [l]  rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule ^([^/]+)/([^/]+)/([^/]+)/?$ displayitem.php?item=$1&start=$2&page=$3 [l,qsa]

the problem occurs while displaying displayitem.php?item=$1. when try execute command, page stay on previous page , displayitem.php not found.

this weird. if comment out following line:

rewriterule ^/?([^/.]+)$ display.php?category=$1 [b,l]

which used pass utf-8 character, works fine , rules executed , parameters passed. however, utf-8 character not passed correctly , echo page not found.

please help!! thanks.

c++ - Delete matches in OpenCV (Keypoints and descriptors) -

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor...

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a...
