OCR software

Filed under: Uncategorized — hwkang @ 4:16 pm

Google has an open source OCR software called: tesseract-ocr http://code.google.com/p/tesseract-ocr/

Seems there’s a problem with the code, at least in Visual Studio, it does not build successfully.  Not sure if it’s true for its Linux version(Tried recently, it works!).

Instead, there’s a free(?) software, which is basically a wrapper for this, called Free OCR: http://softi.co.uk/freeocr.htm

Nomore *-like

Filed under: Uncategorized — hwkang @ 1:53 am

I am pretty sure I am not the only one, who would feel frustrated every time reading a paper using hand-waving *-like phrases, “RANSAC-like”, “Tree-like”, etc.  If the detail is not important, why would one use it in the paper?  If it appears in a paper, please either explain it, or give reference to some sort of technical report.
