Help writing a tracking code for 1 hour of data at a time

Hello,

I am very new to Matlab and am writing a code to analyse some data I have filmed. The code is to track two (relatively large) particles within an area for an hour at a time. I have created a code that states the region of interest, and finds the centre of mass for a single frame of film:

obj=VideoReader('shortvideoM.mov') originalImage= read(obj,1); colormap('gray'),imagesc(originalImage); greyImage=rgb2gray(originalImage); colormap('gray'),imagesc(greyImage); invertImage=255-greyImage; colormap('gray'),imagesc(invertImage); m= invertImage(128.5:302.5,35.5:603.5); colormap('gray'),imagesc(m); blackImage=bpass(m,1,5,5); figure;colormap('gray'),image(blackImage); max= max(max(blackImage)); display(max); pk = pkfnd(blackImage,35,5); cnt = cntrd(blackImage,pk,5); whos cnt figure; hist(mod(cnt(:,1),1),20);

I know that I need to loop the data and then get an array into which to put the coordinates and time, I was just wondering what the general commands are best for this.

Thanks if anyone can help me out, I'm not sure how difficult it is (well very for me).

you may want to use these commands:

save data.mat

and later say

load data.mat

you can put them in a for loop for example
