The project tree is organized as follows.
lib/ directory for utility functions
src/ directory for our c++ implementation of TCD algo

demoTCD.m demo of TCD on discovering temporal commonalities among two sequences
In Matlab shell:
>> cd tcd_v1.3
>> make
>> addpaths
>> demoTCD
You may want to change pickEx in the script to play with other examples.
The script has been tested on Windows 8, Ubuntu 3.11.0 and Mac X 10.9.4 without problems. Please send your feedbacks to Wen-Sheng Chu regarding any issues, bugs and improvements.
Aug-08-2014 * Implemented the main TCD routine in C++ * The speedup against v1.2 is fascinating and can be found here
Jan-06-2013
* Extend TCD with soft clustering and hard clustering
* Speedup TCD search using integral image
* Speedup multiple TCD search using queue elimination
Oct-06-2012
* Add the main implementation of the TCD algorithm
* Add comparisons to the naive SW approach
* Add a demo for 8 synthetic examples, including detecting multiple commonalities and an application to video indexing
