Some researchers from the CVC and the UAB have a MOOC at Coursera on Object detection.
The course started on may 4th but you still have the option to sign in.
It is a 6 week course that introduces the basic principles of any automatic detection and recognition of objects in images. Throughout the course different methods of representation and classification that can address cases of application of increasing complexity will be analysed.
The course is aimed at both university students in some degree related to computer science, engineering or mathematics, as other students with programming skills, interested in learning how to use computer vision techniques to extract information from images.
