Prerequisites

Ubuntu 14.04

cmake 3.2.0

OpenCV 3.1 http://xfloyd.net/blog/?p=987

eigen3

octave (optional, only used for evaluation)

Installation

$ mkdir build

$ cd build

$ cmake ..

$ make

Usage

./mild imagelist.txt settings.yaml

input:

imageList.txt: indicats the path of each input RGB image per line settings.yaml: indicats the parameters used in loop closure detection

output:

output/imagelist/lcd_shared_flag.bin: detected loop closure are set as 1. To be used in the run_scritp.m to check the accuracy of the detected loop closure. output/imagelist/lcd_shared_score_mild.bin: the image similarity calculated using MILD. output/imagelist/relocalization_time_per_frame.bin: lcd time of each frame.

evluation: (based on MATLAB/OCTAVE)
