c++ - opencv stitching with free dll -


i have function in project stitching, function working fine, simple:

mat output(m_img, true), pano; // panaoramic image      bool try_use_gpu = true;     stitcher isticher = stitcher::createdefault(try_use_gpu);        // set feature finder orb     isticher.setfeaturesfinder(new detail::orbfeaturesfinder());      try{          stitcher::status status = isticher.stitch(imgs, pano);         if (status != stitcher::ok)         {             log("error stitching - code: %d", int(status));             return -1;         }     }     catch(exception e)     {         log("cannot stitch image,%s",e.what());     }

the code works , able stitch images well. problem when want deploy code, realized have use non-free dll. otherwise, .exe won't run. questions are: in order use stitcher class opencv mean have pay, even if not using surf or sift algorithms? there way without using "nonfree dlls"? note: using opencv 2.4.2. edit: tested opencv 2.4.11

so, after lot of digging. think have found solution issue: there flag in opencv_modules.hpp called: have_opencv_nonfree if undefine or comment definition of flag , build opencv source should fix issue, i.e. opencv_stitching.dll not depeneds on opencv_non-free.dll

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
