enums - Possibility of assumption in C# -

-

can make assumptions on casted int value of system enums in c#?

for example:

//dayofweek (int)dayofweek.monday == 1, (int)dayofweek.tuesday == 2, (int)dayofweek.wednesday == 3, (int)dayofweek.thursday == 4, (int)dayofweek.friday == 5, (int)dayofweek.saturday == 6, (int)dayofweek.sunday == 0

the logic of code depends on it. however, don't feel writing own mapping, because it... wrong solution.

edit here comes culture thing well. iso standard - monday 1st day. in usa - sunday 1st day.

yes, can rely on it, insofar documented that:

the dayofweek enumeration represents day of week in calendars have 7 days per week. value of constants in enumeration ranges dayofweek.sunday dayofweek.saturday. if cast integer, value ranges 0 (which indicates dayofweek.sunday) 6 (which indicates dayofweek.saturday).

of course, while unlikely so, microsoft free change in future releases.

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
