Domain-Transferred Synthetic Data Generation for Improving Monocular Depth Estimation

no code implementations2 May 2024 Seungyeop Lee, Knut Peterson, Solmaz Arezoomandan, Bill Cai, Peihan Li, Lifeng Zhou, David Han

A major obstacle to the development of effective monocular depth estimation algorithms is the difficulty in obtaining high-quality depth data that corresponds to collected RGB images.

Learning Scene Context Without Images

no code implementations18 Nov 2023 Amirreza Rouhi, David Han

Teaching machines of scene contextual knowledge would enable them to interact more effectively with the environment and to anticipate or predict objects that may not be immediately apparent in their perceptual field.

Generate and Edit Your Own Character in a Canonical View

no code implementations6 May 2022 Jeong-gi Kwak, Yuanming Li, Dongsik Yoon, David Han, Hanseok Ko

Although the progress of generative models enables the stylization of a portrait, obtaining the stylized image in canonical view is still a challenging task.

CPNet: Cross-Parallel Network for Efficient Anomaly Detection

1 code implementation10 Aug 2021 Youngsaeng Jin, Jonghwan Hong, David Han, Hanseok Ko

Anomaly detection in video streams is a challenging problem because of the scarcity of abnormal events and the difficulty of accurately annotating them.

DLA: Compiler and FPGA Overlay for Neural Network Inference Acceleration

no code implementations13 Jul 2018 Mohamed S. Abdelfattah, David Han, Andrew Bitar, Roberto DiCecco, Shane OConnell, Nitika Shanker, Joseph Chu, Ian Prins, Joshua Fender, Andrew C. Ling, Gordon R. Chiu

Overlays have shown significant promise for field-programmable gate-arrays (FPGAs) as they allow for fast development cycles and remove many of the challenges of the traditional FPGA hardware design flow.
