03 Feb 2012 Bezier Curve Plotter constructs a Bezier curve using a given set of control points Author: Sagar Aiya

Great, but code could be vectorized with huge improvment for data with large number of sampling points. I have posted the vectorized code here:

Thanks, this is fantastic.

Thanks... Could it be possible to add circular and mirror boundary conditions and non-uniform nodal points?

Prakash.

01 Jan 2014 Simple demo program for color based tracking Simple script to read a video file and track a single red marker in 2D using hue and saturation. Author: Prakash Manandhar daher

Hi Prakash,
I have a question if you dont mind. Assuming that i have to track the first identified blue colored object that appears in a video. After a couple of frames other objects with the same hsv parameters appear ( noise). My tracker will be found in a typical local minimum problem. If i dont want to refer to the geometry of each object separately ( which will consume time and energy), what will be the ideal filter to use in a way that whatever will appear in the video, the tracker will always go after the first object. I have asked this question everywhere, including here, cant find a proper hint.. Thanking you

Yes, there is a problem with this function.
