Today:

Bootcamp demo session

Ran bootcamp demo session. Final code available at

svn+ssh://v01/misc/svn/src/bootcamp/kjb_demos/3d_demo

Ground truth labeling of curve fragments

Goal: use 2D ground truth to automatically label bottom-up curve fragments.

Overview

  1. Draw ground truth curves using curve index
  2. dilate slightly
  3. For each rendered data curve, gather all GT indices
  4. keep most-occurring GT index.
  5. add to assoc list for that curve

Issues:

Q: Remember how to read and process ground truth.
A: See ../ground_truth/read_gt2.m

Symlinked to train/read_gt2.m.

Q: Which dataset does our example data come from?
A: ~/data/arabidopsis/2010-06-03/ler_5_36/ler_5_36_0.jpg

Q: Where is ground truth data?
A: ~/data/arabidopsis/2010-06-03/ler_5_36/resized_50%/ground_truth_2d.gt2

Blah Blah

Refactored some code into new function build_curve_maps.m, which renders each of the curves in a cell-array into a map containing their indices.

Forgot that GT is stored as Bezier curves. Symlinked the all bezier-related code into data_association_2. Relevant function is bezier/polybez_to_polyline.m.

Forgot that GT is stored in OpenGL-style coordinates (bottom-left origin). Converting to top-right using tools/flip_y.m.

Summary

Got through item 2 in "Overview" above. Will finish next time, and start building training framework.
