Extracting data from a sequence of images

Hi everyone,

I need some help on my research related with PIV technique. I have a sequence of images of the evolution of the particles inside a flow between two cylinders where the inner cylinder is rotating. A DPIV code generate a matrix data of the velocity and the position of the particles through different radios. Now i need to add a time vector because i need to plot the evolution of the transient velocity but i dont know how i can do that. I will apreciate any kind of help. I have attached an image of what i want to obtain.

Thank you in advance.

Use dir() to get the time/date stamp of each image file. You can use that to build up your time vector for your x axis.
