Query: Gait Recognition with Mask-based Regularization   Most gait recognition methods exploit spatial-temporal representations from
static appearances and dynamic walking patterns. However, we observe that many
part-based methods neglect representations at boundaries. In addition, the
phenomenon of overfitting on training data is relatively common in gait
recognition, which is perhaps due to insufficient data and low-informative gait
silhouettes. Motivated by these observations, we propose a novel mask-based
regularization method named ReverseMask. By injecting perturbation on the
feature map, the proposed regularization method helps convolutional
architecture learn the discriminative representations and enhances
generalization. Also, we design an Inception-like ReverseMask Block, which has
three branches composed of a global branch, a feature dropping branch, and a
feature scaling branch. Precisely, the dropping branch can extract fine-grained
representations when partial activations are zero-outed. Meanwhile, the scaling
branch randomly scales the feature map, keeping structural information of
activations and preventing overfitting. The plug-and-play Inception-like
ReverseMask block is simple and effective to generalize networks, and it also
improves the performance of many state-of-the-art methods. Extensive
experiments demonstrate that the ReverseMask regularization help baseline
achieves higher accuracy and better generalization. Moreover, the baseline with
Inception-like Block significantly outperforms state-of-the-art methods on the
two most popular datasets, CASIA-B and OUMVLP. The source code will be
released.
