Hello All, I am trying to measure fluid velocity in an AVI file, and am doing this by converting each frame to an image and measuring the mean intensity of the pixels in two different windows spaced out. Now that I have two different signals that should be theoretically time delayed, I need to cross correlate them to see the time delay, but I am having trouble with xcorr. I seem to obtain the sig...

Hi Is there any way to find the coordinates of a contour's points? for example, in computing the contour of an image, we want the points displayed by the contour. Actually the output of the function 'contour' is two variables for object handle and a matrix including grouped points based on contour value. but they are not the real positions Thanks

Hi all, Thanks for your responses. Actually, none of what you said worked for me unfortunately. Sorry. I found this command fitsinfo in the manual. This is actually used to get information about a FITS (Flexible Image Transport System) file. However, if someone is interested only in the size of a file, this seems to be doing the job. In my case, I had a
