Unsupervised Sketch to Photo Synthesis

no code implementations ECCV 2020 Runtao Liu, Qian Yu, Stella X. Yu

Humans can envision a realistic photo given a free-hand sketch that is not only spatially imprecise and geometrically distorted but also without colors and visual details.

Strengthening Multimodal Large Language Model with Bootstrapped Preference Optimization

no code implementations13 Mar 2024 Renjie Pi, Tianyang Han, Wei Xiong, Jipeng Zhang, Runtao Liu, Rui Pan, Tong Zhang

To mitigate this issue, we propose Bootstrapped Preference Optimization (BPO), which conducts preference learning with datasets containing negative responses bootstrapped from the model itself.

The Emergence of Objectness: Learning Zero-Shot Segmentation from Videos

1 code implementation NeurIPS 2021 Runtao Liu, Zhirong Wu, Stella X. Yu, Stephen Lin

Our model starts with two separate pathways: an appearance pathway that outputs feature-based region segmentation for a single image, and a motion pathway that outputs motion features for a pair of images.

3D Shape Reconstruction from Free-Hand Sketches

1 code implementation17 Jun 2020 Jiayun Wang, Jierui Lin, Qian Yu, Runtao Liu, Yubei Chen, Stella X. Yu

Additionally, we propose a sketch standardization module to handle different sketch distortions and styles.

CLEVR-Ref+: Diagnosing Visual Reasoning with Referring Expressions

3 code implementations CVPR 2019 Runtao Liu, Chenxi Liu, Yutong Bai, Alan Yuille

Yet there has been evidence that current benchmark datasets suffer from bias, and current state-of-the-art models cannot be easily evaluated on their intermediate reasoning process.
