Data

Download data from here and unzip it unzip data.zip.

It contains the LOMO feature [1] and kCCA feature [2] for VIPeR dataset.

Run

run demo.m in Matlab.

Results

We used the VIPeR data split provided by [2] in https://github.com/glisanti/KCCAReId.

For LOMO feature, we can get reported result 42.28% on VIPeR. (RBF kernel).

For kCCA feature, we can get 46.68% (CHI2 kernel), 45.92% (RBF kernel).

We can get reported score-level fusion result 51% on VIPeR.
