Target Tracking
I did a target tracking project this week I thought it turned out nice so I'm gonna share it here

the program reads a video file, finds the mouse in the video and highlights it (that red box at the tip of the mouse), the red box is actually added by a computer. nothing special for a computer major but for me as a mechanical engineer was very exciting. the same technology is used in robot vision or target tracking in missiles

حالا چطوری کردی؟ همبستگی یک هر جزء از تصویر با نشانگر ماوس رو حساب کردی و هر جا ماکزیمم بود رو به عنوان نشانگر انتخاب کردی؟


یا اینکه یک روشی استفاده کردی که با نشانگرهای مختلف هم درست تشخیص می‌ده؟

Madjid jan, its not using pattern matching or any kind of correlation .pattern matching does not work on this kind of problem (however it works fine on OCR) whenever the mouse goes on a line pattern matching loses track, I guess unless you mix it with a neural net you wont get anything useful out of correlations in this case. I have used some basic edge detection algorithms so regardless of the shape of the mouse it finds it
