How hard can it be to make a computer to recognize text from pictures? As a part of Data Mining course in Fall 2009, me and Jaana implemented a small program that extracted letters from pictures and then recognised them.
- Project report
- Presentation
- Pictures of 242 words that were used in the experiments
- OpenCV C++ code used for image preprocessing and feature extraction
- Clean data matrix for machine learning
- Column 1: character from a-z
- Column 2: aspect ratio (height divided by width)
- Columns 3-130: 16 x 8 normalized pixel values
