c++ - Losing Part of Image When Using DrawImage on Panel -

-

i making winforms app hd images (1920 x 1080) displayed on panel control. images hd webcam. panels smaller (240 x 135) images , having problem getting images resize , display in panels. crash outright , other times image not resized.

the images bitmaps , redrawing them in paint event control.

here code paint event handler.

void cam0panel_paint( object^ /*sender*/, system::windows::forms::painteventargs^ e ) {     system::drawing::bitmap^ b = imagewinarray[channel_select0];     graphics^ g = e->graphics;      g->interpolationmode = system::drawing::drawing2d::interpolationmode::bilinear;     g->compositingmode = system::drawing::drawing2d::compositingmode::sourcecopy;     g->drawimage(b,system::drawing::rectangle(0,0,cam0panel->right,cam0panel->bottom)); }

i specifying top, left point in panel (0,0) , image resized panel size. reason not working.

any appreciated.

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
