Hi,
I have a movie that contains a particle moving from one end of a channel to another end. The velocity of the particle is super-fast.
I need to know how I can estimate the time and be able to pictorially tell when the particle is at each of the ends....I don't care too much about the intermediate path.
Someone told me that for each frame I need to calculate where the spot is,by picking wherever the brightest pixel is or by frame to frame subtracting, calculating means & standard deviations, thresholding, etc...
How do I write this code? How do I locate the particle on the video and find the standard/deviation etc of its position? In other words, how do I apply the statistical functions to my particle on the video?

The Computer Vision System Toolbox has several demos on tracking: http://www.mathworks.com/help/toolbox/vision/vision_exampleindex.html
