Bengali Handwritten Grapheme detection
The problem
Automatic handwritten character recognition (HCR) and optical character recognition (OCR) are quite popular for commercial and academic reasons. For alpha-syllabary languages this problem increases manifolds due to its non-linear structure. Bengali, a member of alpha-syllabary family, is way trickier than English as it has 50 letters - 11 vowels and 39 consonants - plus 18 diacritics. This means there are roughly 13,000 ways to write Bengali letters, whereas English only has about 250 ways to do the same. This huge number of combinations makes recognizing Bengali characters a lot harder. These different elements has been shown below for a visual understanding.
