Counting number of people by image capturing

[iamcoconut]

Hi!

i am an university student, recently i have received a image processing research project. my tutor ask me to count number of people by capturing the image. It is a huge task for me. Because human contour variation is huge, and difficult to have standard shape. i still have no idea in this field. Does anybody has ideas or resources for this??

Pls help!!!

Thanx alot

Hi iamcoconut,

You can use the pattern matching functions in IMAQ Vision to search for complex images, such as a set of eyes, etc. However, if you are going to have images of people from different angles, the best method to find the people is to use a Static Background type analysis. This analysis takes an image of the background without people in it and then acquires an image of the same background with people in it. Performing a simple subtract and then separating the images, removing particles, etc. isolates your people so that they may be "counted."
