I have a site that creates passportphotos I would like to integrate face detection in my site like in:[url removed, login to view]
the best(and free) option is to use emgu cv. the site is built in ASP and currentlly the cropping is being done using jquery based on user selection(which is more error prone).
I would like to implement auto croping using face detection(like in the mentioned site).
I write here its simple project becuase I think emgu cv is well documented and there are a lot of similar examples you can use but I don't know exactlly know what investment it demands.
