GaitSTR: Gait Recognition with Sequential Two-stream Refinement

no code implementations2 Apr 2024 Wanrong Zheng, Haidong Zhu, Zhaoheng Zheng, Ram Nevatia

We demonstrate that with refined skeletons, the performance of the gait recognition model can achieve further improvement on public gait recognition datasets compared with state-of-the-art methods without extra annotations.

Gait Recognition Using 3-D Human Body Shape Inference

no code implementations18 Dec 2022 Haidong Zhu, Zhaoheng Zheng, Ram Nevatia

Gait recognition, which identifies individuals based on their walking patterns, is an important biometric technique since it can be observed from a distance and does not require the subject's cooperation.

Utilizing Every Image Object for Semi-supervised Phrase Grounding

no code implementations5 Nov 2020 Haidong Zhu, Arka Sadhu, Zhaoheng Zheng, Ram Nevatia

The annotated language queries available during training are limited, which also limits the variations of language combinations that a model can see during training.
