Abstract:
The report describes work in progress in each of the stages of the analysis of graphical data specifically, the recognition of hand-printed FORTRAN test. These stages are data preparation input of data to the analysis system preprocessing classification and contextual analysis. A preprocessing and classification method adapted from Jon K. Clemens of MIT was programmed and tested on characters from the data base. The best results were obtained for alphabetic characters only 58 correct, 23 errors, and 19 rejects. The beginnings of work, directed at improving the recognition rate through the use of contextual relations among individually classified characters, are described. A small study showing that the recognition rate by humans of characters without context is on the order of 99, and that the quantization performed during input to the system reduces this rate only slightly.
