Semi-supervised Domain Adaptation for Semantic Segmentation

no code implementations20 Oct 2021 Ying Chen, Xu Ouyang, Kaiyue Zhu, Gady Agam

We demonstrate that the proposed approach outperforms state-of-the-art methods on two common synthetic-to-real semantic segmentation benchmarks.

Mask-based Data Augmentation for Semi-supervised Semantic Segmentation

no code implementations25 Jan 2021 Ying Chen, Xu Ouyang, Kaiyue Zhu, Gady Agam

Training a CNN to perform semantic segmentation requires a large amount of labeled data, where the production of such labeled data is both costly and labor intensive.

Accelerated WGAN update strategy with loss change rate balancing

no code implementations28 Aug 2020 Xu Ouyang, Gady Agam

Optimizing the discriminator in Generative Adversarial Networks (GANs) to completion in the inner training loop is computationally prohibitive, and on finite datasets would result in overfitting.

Layered Optical Flow Estimation Using a Deep Neural Network with a Soft Mask

no code implementations9 May 2018 Xi Zhang, Di Ma, Xu Ouyang, Shanshan Jiang, Lin Gan, Gady Agam

We show that by using masks the motion estimate results in a quadratic function of input features in the output layer.
