Objectives/Deliverables for Indic Meet

I shall first demonstrate the working of the OCR on some sample images. Then I plan to explain the working of the OCR system on a higher level. It shall be followed by a demonstration of the problems that exist in the present system and potential solutions that I have in mind. I shall demonstrate how to train this OCR for a particular language. This should be over in 75 minutes.
Then we move on to the problems I am facing. We have a discussion on possible solutions. Here are a few problems to tackle:

1) Learning about the various efforts made in the past. BOCRA / Aksharbodh etc
2) Dealing with the post-OCR spell-checker problem
3) A better segmentation algorithm. Ocropus Curved cut segmenter. Merits/demerits
3) Reducing number of character classes to be trained as explained at
4) Talk to Santhosh Thottingal about integrating the service to Silpa
5) How to build a web interface that can train the OCR engine from user input.
