Active Basis C++ Code (Compact Memory) + INRIA Person Data

1. Introduction

This code is downloadable at active_basis_cpp_inria_compmem.
Based on the code active_basis_cpp_inria_small, I remove mI, xI, yI, indI, and compute them on the fly when they are needed. In addition, I have migrate to use boost::program_options to read parameters.
Now I use the images in original size 57x148.

2. Results

The results with adaptive background subtraction are encouraging.
There default parameters are as below:
epsilon=0.1
L=3
ore=1
SHUTUP=0.0
sub=2
Totalsketch=40
NumCluster=2
NumIt=2

The table lists AUC.
