What functions are available to do pattern recognition in MATLAB?
I would like to develop algorithms for object and pattern recognition using the Image Processing Toolbox.

Object recognition is a challenging problem. MATLAB and the Image Processing Toolbox have various analytical, image processing, and statistical tools that can be used to develop recognition algorithms. The task is not a trivial one.
Beyond suggesting image processing textbooks (Digital Image Processing by Gonzalez and Woods, Image Processing Handbook by Russ, etc.), our Technical Support staff does not have the necessary resources to assist with the development of such algorithms. However, we can point you to some examples and functions that will give you a better idea of our tools.
Here is an index of examples of image processing topics, such as morphology and registration. Type the following at the MATLAB command prompt to open the help browser to the page of Image Processing demos:
For the Image Processing Toolbox 3.2 (R13) and previous:
ipexindex
For the Image Processing Toolbox 4.0 (R13+) and later:
iptdemos
We recommend reading each of the following demos in the Image Processing Toolbox 3.2 (R13) and previous:
Morphology Demos
- Detecting Microstructures Using Image Segmentation
- Detecting a Cell Using Image Segmentation
- Detecting Touching Objects Using Watershed Segmentation
- Finding the Granulometry of Stars in an Image
Registration Demos
- Registering an Image Using Normalized Cross-Correlation.
We recommend reading each of the following demos in the Image Processing Toolbox 4.0 (R13+) and later:
Measuring Image Features
- Finding the Length of a Pendulum in Motion
- Granulometry of Snowflakes
- Identifying Round Objects
- Measuring Angle of Intersection
- Measuring the Radius of a Roll of Tape
Morphology Segmentation
- Detecting a Cell Using Image Segmentation
- Marker-Controlled Watershed Segmentation
Registration Demos
- Registering an Image Using Normalized Cross-Correlation.
There are also several demos of pattern and object recognition available on MATLAB Central. They are as follows:
Target Detection System
Character Recognition Example
