+Feature Extraction
+==================
+
+VIPeR specific
+
+publicly available Feat-ext source:
+https://github.com/rlayne/ELF-v2.0-Descriptor
+
+Requirement:
+matlab(tested with R2014b & R2015a under linux)
+bash/zsh(as default shell or change shebang to #!/bin/bash)
+
+How to use:
+./genRid.sh cam
+change cam to the directory name of dataset
+
+Structure:
+./genRid.sh
+    ./runMatlab.sh -> call matlab script or functions
+        ./parGetVecs.m -> calculate vectors of images in 'cam_a' & 'cam_b' to a.txt & b.txt
+            ./getVecsM.m -> get maximum % minimum
+            ./getVecs.m -> get histo using previously calculated maximum & minimum
+    combine a.txt b.txt to cam.rid
+
+!!Feature size is hardcoded, change in ./genRid.sh & ./parGetVecs.m!!
+
+Clean-up:
+redundancy in ./getFeatureExt.m & ./genFeatureVec.m
