Lattice Editor
Members: Kyle Brocklehurst, Yanxi Liu

Project Description
We seek to create a user interface for labeling and editing ground-truths for lattice detection algorithms.

We used this interface to create ground truths for our PAMI paper:

Deformed Lattice Detection in Real-World Images using Mean-Shift Belief Propagation, in IEEE Transaction on Pattern Analysis and Machine Intelligence (PAMI). Special Issue on Probabilistic Graphical Models Volume 31, Number 10 in October 2009.

It allows the user to draw a lattice structure to indicate the repeating pattern in an image. Editing tools allow the user to fine-tune the ground-truth or edit the results of a detection algorithm. Results are saved to a text file easily accessible with MATLAB or C++ (code provided).

Our method for automatic evaluation of a detected lattice against a ground truth is also included. This provides a well-justified, quantitative evaluation of the performance of a detection algorithm against a ground-truth.

Eventually, the program will include a tool for computer-aided lattice identification, allowing faster and more accurate labeling.
