@User800222 Maybe you get better results asking this at SE Code Review. Be sure to meet their policies though (e.g. include enough context of what the code is supposed to do). — πάντα ῥεῖ 1 min ago

You should check out the help center for guidance on what's appropriate here on Stack Overflow. While you might get better help on CodeReview for this kind of question (optimizing for performance), I don't think your question is unacceptable here on the main Stack Overflow site, as long as it is complete and not completely dependent on a link to an external site. The edit made by another user has improved it a bit. Feel free to edit it further yourself to improve it (but you should usually not change your code, as that might invalidate answers that comment on what you were doing). — Blckknght 46 secs ago

Q: What is needed to write functions with good performance like OpenCV does

User800222I've tried to implement my own canny edge detector and tried to make it as fast as possible. I tried to code most of the needed function myself and only used opencv as input/output. However, the performance isn't comparable to opencv's cv::Canny() when input's size get larger. Even using OpenMP...

This is better suited to the codereview.stackexchange.com, but I will tell you that traditional for() loops are the fastest loops in JavaScript, and that Array.prototype.push is very slow. So if there was a different data structure you can use do that and replace the `while'. — Randy Casburn just now
