In this paper we address the issue of recognizing Farsi handwritten words. Two types of gradient features are extracted from a sliding vertical stripe which sweeps across a word image. These are directional and intensity gradient features. The feature vector extracted from each stripe is then coded using the Self Organizing Map (SOM). In this method each word is modeled using the discrete Hidde...

Applying Domain Knowledge to the Recognition of Handwritten Zip Codes

We present a simple system that exploits domain knowledge to improve the segmentation and recognition of handwritten ZIP codes. Specifically, we show that the concept of metaclasses of digits, introduced by Morita et al. [16] for recognition of Brazilian bank check dates, can be extended to ZIP code recognition. We also show that, when this domain knowledge is present, integrated segmentation a...

Automatic Zip Code Reader

Computers excel at performing quantitative and repetitive tasks quickly, but they struggle with qualitative tasks, such as handwriting recognition. This is because it is effectively impossible to program recognition of millions of different handwriting styles into one algorithm. However, with the advent of machine learning, computers can be trained to recognize unknown objects and characters by...
