Unifying Tracking and Image-Video Object Detection

no code implementations20 Nov 2022 Peirong Liu, Rui Wang, Pengchuan Zhang, Omid Poursaeed, Yipin Zhou, Xuefei Cao, Sreya Dutta Roy, Ashish Shah, Ser-Nam Lim

We propose TrIVD (Tracking and Image-Video Detection), the first framework that unifies image OD, video OD, and MOT within one end-to-end model.

Object-Centric Unsupervised Image Captioning

1 code implementation2 Dec 2021 Zihang Meng, David Yang, Xuefei Cao, Ashish Shah, Ser-Nam Lim

Our work in this paper overcomes this by harvesting objects corresponding to a given sentence from the training set, even if they don't belong to the same image.

Differential Motion Evolution for Fine-Grained Motion Deformation in Unsupervised Image Animation

no code implementations9 Oct 2021 Peirong Liu, Rui Wang, Xuefei Cao, Yipin Zhou, Ashish Shah, Ser-Nam Lim

Key findings are twofold: (1) by capturing the motion transfer with an ordinary differential equation (ODE), it helps to regularize the motion field, and (2) by utilizing the source image itself, we are able to inpaint occluded/missing regions arising from large motion changes.

Unsupervised Deep Metric Learning via Auxiliary Rotation Loss

no code implementations16 Nov 2019 Xuefei Cao, Bor-Chun Chen, Ser-Nam Lim

In this work, we propose to generate pseudo-labels for deep metric learning directly from clustering assignment and we introduce unsupervised deep metric learning (UDML) regularized by a self-supervision (SS) task.
