Modified xfloat in latex causes runaway argument -

-

i required use customized document class modifies xfloat...

\input{report.cls}  % single space figures, tables, , footnotes % redefine macro used floats (including figures , tables) % single spacing used.  (note \def\figure{\@float{figure}set % single spacing} doesn't work because figure has optional argument) \def\@xfloat#1[#2] {   \ifhmode     \@bsphack\@floatpenalty -\@mii   \else     \@floatpenalty-\@miii   \fi   \def\@captype{#1}   \ifinner     \@parmoderr\@floatpenalty\z@   \else\@next\@currbox\@freelist {     \@tempcnta\csname ftype@#1\endcsname     \multiply\@tempcnta\@xxxii\advance\@tempcnta\sixt@@n     \@tfor \@tempa :=#2\do {       \if\@tempa h\advance\@tempcnta \@ne\fi       \if\@tempa t\advance\@tempcnta \tw@\fi       \if\@tempa b\advance\@tempcnta 4\relax\fi       \if\@tempa p\advance\@tempcnta 8\relax\fi     }     \global\count\@currbox\@tempcnta   } \@fltovf\fi   \global\setbox\@currbox\vbox\bgroup   \def\baselinestretch{1}\@normalsize   \boxmaxdepth\z@  % leave captions indented, hope % \hsize\columnwidth   \@parboxrestore }

however, when creating document float...

\documentclass{customclass} \begin{document} \begin{figure} test \end{figure} \end{document}

i error...

runaway argument? tbp]test \end {figure} ! paragraph ended before \@xfloat complete. \par l.7

it appears line breaking causing issue. putting whole block in document class on same line fixes issue.

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
