Set of discrete tasks for Schrift (the name of the proposed handwriting recognizer).
These notes and more are are kept on paper.

  • File structuring
    • just doing it, will restructure later.
  • Image importing
    • Read in jpg image
  • Text Scan
    • OpenCV image import, test threshold filter
    • Algorithm for figuring out correct threshold value. Take a mean of the page color and adjust for that value. Usually 110±10?
    • Draw box around where dark is detected, extract that selection.
  • Line segmentation
    • Decided it was not necessary to find beginning and end of line
    • General Algorithm
      • Scan from top line by line
      • Stop when line of nothing
      • create selection between line1 and line2
      • push to dynamic array as line[0]
  • Word segmentation
    • Outline algorithm similar to line segmentation
  • Character segmentation
    • openCV historgram test

11-26-12: I tried an openCV example that makes and highlights bounding box and bounding polygon regions, it gave me this image. Suddenly I'm on the recognition step??

  • Character recognition
    • Figure out a basic neural network
      • look atOpenCV neural network type
      • I've found some NN tutorials, the implementation of one is what's bothering me.
