measuring distance between two points in an image

[hitha]

Sir,

I am working on an eye gaze tracking project. for this, i need to measure the distance between the center of the eyes to inner corner and center of the eyes to the outer corner and display the values. I have to repeat this for all the frames of the video recorded using the webcam. Kindly help me out with this issue asap. 

i havent at all progressed in this.. so i have not got anything to attach.

Please help me.

Define inner and outer corner. Can you attach a typical frame picture?

Do you need help finding the center and corners (maybe hard) or do you already have the pixels coordinates (trivial).

i need to find out that as well... and i havent yet progressed at all...

Can u help me regarding that too sir,..?

It seems like even defining the problem is more effort than you feel like putting in. This is why you don't progress.

I am really new to labview.. thats the reason why i cant figure out what to do..

[ToeCutter]

Well 'i'm really new' is often a codeword around here for someone that hasn't even sat down to learn the basics of LabVIEW. You need to read the manual and go through some tutorials/exercises if you haven't already. Depending on your license, you may have free access to the LabVIEW core training programs.

So, the main problem is the image analysis. You have not shown us a tyical picture as requested.

is it color? black&white? What is the resolution? What is the frame rate you need?

So many questions, so little information!

 The image is color..il attach one..

frame rate is 30fps..
