c++ - Vector<Vec3b> difference with Vector<int> in OpenCV -

-

my project moving puck detection , location finding on hockey table. need use houghcircles detect circular form of puck. hough alghoritm need make vector. familiar vector concept , how working ( basic), there problem of differentiating example vector<int> vec , vector<vec3b> vec.

is possible let me know difference in meaning , application?

pay attention vector , vector different. vector std::vector, while vector cv::vector. if in practice difference minimal, different things.

i'll assume meant std::vector, in context valid cv::vector.

a vector<int> vector of integers. nothing fancy this.

a vector<vec3b> vector of cv::vec3b, opencv structure holds 3 uchar (unsigned char), i.e. type 8 bit can contain data 0 255. in fact defined cv::vec_<uchar, 3>. cv::vec template class represents short numerical vectors, 4 elements, not important here.

a vec3b used in opencv store color pixel, b,g,r triplet.

filehandler - java open files not cleaned, even when the process is killed -

-
there java program read files folder, processing , write output files in folder. ran 4 hours , produced few files failed after throwing following error: "too many files" then modified program close (bufferreader , bufferwriter) , started process again. time process failed after starting throwing following error: java.io.filenotfoundexception: <file> (too many open files) then tried running lsof , searched process having no of open files. realized networkmanager. not sure whether should kill process or not. restarted machine. after when ran java program, still got same error. in worst case might possible code still having leaks in terms of not closing everything, still failing after starting process. have feeling lying in system previous run. if start same process in other machine, runs hours before failing. you cannot retain resource between runs of program, if wanted to. leave system without enough resources in theory, though unlikely, restarting...

Sass watch command compiles .scss files before full sftp upload -

-
i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
