Show HN: pXY.js - pixel analysis for HTML5 Canvas

1 point

14 years ago

This lib provides a pleasant interface for analyzing <canvas> pixels in an effort to speed up implementation, readability and debugging of custom analysis algorithms such as document feature extraction, OCR segmentation, etc.

Why?

I needed an interactive tool that would assist (a team of monkeys) in recognizing a document structure from rasterized or scanned PDF forms because automated tools like Omnipage and Finereader offer no efficient method of form field data-binding, auto field naming, schema mapping and so forth. While the actual algorithms and the tool is closed-source for now, pXY.js was written to serve as the core.
