Feature representation and metric learning are two critical components in
person re-identification models. In this paper, we focus on the feature
representation and claim that hand-crafted histogram features can be
complementary to Convolutional Neural Network (CNN) features. We propose a
novel feature extraction model called Feature Fusion Net (FFN) for pedestrian
image representation. In FFN, back propagation makes CNN features constrained
by the handcrafted features. Utilizing color histogram features (RGB, HSV,
YCbCr, Lab and YIQ) and texture features (multi-scale and multi-orientation
Gabor features), we get a new deep feature representation that is more
discriminative and compact. Experiments on three challenging datasets (VIPeR,
CUHK01, PRID450s) validates the effectiveness of our proposal.

本文提出 Feature Fusion Net 模型，使用手工制作的直方图和纹理特征，能够与卷积神经网络 (CNN) 特征互补，可以得到一个更具区分性和紧凑的深度特征表示，并在 VIPeR、CUHK01 和 PRID450s 三个数据集上进行了验证。
