Course: Artificial Intelligence

Project: Heuristic evaluation function for Mancala Game Overview: I developed a heuristic evaluation function for ‘Mancala Game’ (two-player game) in ‘LISP’ Programming language using ‘MIN-MAX’ algorithm is used to find out the best move a player could choose in a search-space based on heuristic- value of the board. ‘Alpha-Beta’ pruning is used in ‘MIN-MAX’ algorithm to cut down unnecessary parts of the search. Course: Computer Vision

Project: Script Identification of a Trilingual document Overview: The Project aims to classify three scripts from a document. The three scripts chosen are ‘English’, ‘Kannada’ and

‘Hindi’. The implementation uses four features to classify a line in the document. These features are chosen using ‘Local Approach’ to Script Identification. In ‘Local Approach’, features are chosen based on the distribution of pixels in the line. Education:
