See section 23.4:

For example:

Computer recognition of printed Tamil characters,
PR(10), No. 4, 1978, pp. 243-247.
Chinnuswamy, P., Krishnamoorthy, S.G.,
Recognition of handprinted Tamil characters,

Maybe you just want a simple template matching app using normxcorr2() that doesn't really care about Tamil characters, it just looks for matching patterns of gray levels, like Chandra gave here: http://www.mathworks.com/matlabcentral/answers/24467-identifying-objects-in-a-picture-containing-several-objects
