pXY.js - pixel analysis for HTML5 Canvas
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.
I needed an interactive tool that would assist humans 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.
