Research Topics in Computer Vision

Posted by Abhishek on August 2, 2006, 12:50 pm

Hi,
I am on lookout for a challenging research topic in Computer
Vision which I can work on for about a year and come out with a
successful implementation of the same in MATLAB and then in C. I did
some research over the internet and also have come out with few ideas
on face ecognition/gesture recognition and 3D modelling and so on. Can
you please suggest me a good research topic which you people feel you
should have taken it up few years back but didn't actually work on for
whatever reason it may be? I am looking out for a topic involving
PATTERN RECOGNITION, NEURAL NETWORKS, GEOMETRY AND IMAGE PROCESSING. I
know thats a very broad way of naming the topics but I thought I will
take ur choices into account before starting off.
Waiting for your suggestions on the different topics.

With Regards,
Abhishek S

Read this guy's articles and you may get some ideas:

Choose something you are interested in and a project that you think you
will use later on in life or at your next job.

I would not suggest you spend any time on Neural Networks. I took some
graduate digital signal processing courses in neural networks and they
really dont work for anything other than very simple problems that
could be solved more predictably by seat-of-your-pants C code.

I have to agree in parts with howy. I would study NN only enough to see that
you can do the same thing and much more with statistical methods (Monte
Carlo, Bayes, Hidden Markov Models, EM, etc). Some people say that NN is
nothing more than a statistical method with a neat name.

All this said, I still intend to get back to NN research in the future, but
using more realistic neural models.

For computer vision, I would also include in your toolbox things like
fourier transforms, wavelets, hough transforms and the basic digital image
processing stuff.

Cheers

Facial gender discrimination of humans. Note that
adrogenous *is* a valid answer. See how well
your algorithms stack up against a sampling of
college students, using a fixed data set.

Cheerios,
