jquery - CORS asyncronous ajax call with xhrFields is not working across all browsers (IE8) -

-

i'm making ajax call across cross domain url , fails in ie8 using below code.it fails in ie8 error object or property not defined, , gives response undefined. have set , $.support.cors = true; $.ajax({
async: false, cache: false, url: "http://test/price", crossdomain: true, type: "post", datatype: "json", data: jsondata,
xhrfields: { withcredentials: true }, success: function (response) { } error: function (xhr, exception) { } above code works in firefox , chrome browsers. make work in ie8, removed below part of code xhrfields: { withcredentials: true },

now works in ie8, ie8+ browsers fails in chrome , firefox , complains "401 - unauthorized: access denied due invalid credentials.you not have permission view directory or page using credentials supplied"

i tried forcing in header section in ajax call using below code, it's of no use. headers: {
"content-type":"application/x-www-form-urlencoded", "access-control-allow-origin": "*", "access-control-allow-credentials":"true", "access-control-allow-headers":"content-type, origin, authorization, x-requested-with, accept", "access-control-allow-methods": "post" }

i tried suggestions in posts, none worked can please me fix in ie8+, chrome , firefox browsers.

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...
