I have been playing around with image processing using Mathematica and
have started to do some reading to learn some of the fundamentals of
image processing. I want to be able to build a machine that can
recognize basic hardware items nuts, bolts, washers, screws,
springs, ... as they go down a conveyor belt in single file and also
once they are identified classify them by size. I plan to have a
digital camera take a picture of the item as it passes by and then do
some image processing in Mathematica to determine the type of object
and size.
After I master some of the fundementals, what books should I read on
image processing and topics, algorithms on image processing should I
study in more depth to learn how to do this specific type of object
recognition?
Any help would be greatly appreciated. Thanks |

This type of object recognition would be covered in the fundamentals,
unless you have the objects overlap, in which case it gets trickier.
There are lots of books on image processing. Personally I like the
Handbook of Image Processing by John Russ because it deals with a very
wide variety of subjects/samples (i.e. it's not all medical or remote
sensing - it has lots of different scenes). Perhaps there is a book
more targeted towards machine vision (industrial inspection) that
would be more focused for what you want. |

I think few textbooks address shape recognition. It's a relatively
advanced topic that texts liks Gonzalez and Woods or Jain simply don't
have enough pages to cover.
<http://www.amazon.com/Digital-Image-Processing-Rafael-Gonzalez/
dp/013168728X/ref=sr_1_1?ie=UTF8&s=books&qid=1255396622&sr=8-1>

Two important papers on shape recognition are:
Active Appearance Models (Cootes)
http://en.wikipedia.org/wiki/Active_appearance_model
http://citeseer.ist.psu.edu/old/723056.html
Scale-invariant feature transform (Lowe)
http://en.wikipedia.org/wiki/Scale-invariant_feature_transform
http://www.cs.ubc.ca/~lowe/papers/ijcv04.pdf
In both cases, you can probably find free source code on the web
to get started. But Matlab is much more popular for imaging than
Mathematica.
