Exploiting Invariance in Training Deep Neural Networks

1 code implementation30 Mar 2021 Chengxi Ye, Xiong Zhou, Tristan McKinney, Yanfeng Liu, Qinggang Zhou, Fedor Zhdanov

Inspired by two basic mechanisms in animal visual systems, we introduce a feature transform technique that imposes invariance properties in the training of deep neural networks.

EV-IMO: Motion Segmentation Dataset and Learning Pipeline for Event Cameras

no code implementations18 Mar 2019 Anton Mitrokhin, Chengxi Ye, Cornelia Fermuller, Yiannis Aloimonos, Tobi Delbruck

In addition to camera egomotion and a dense depth map, the network estimates pixel-wise independently moving object segmentation and computes per-object 3D translational velocities for moving objects.

LightNet: A Versatile, Standalone Matlab-based Environment for Deep Learning

1 code implementation9 May 2016 Chengxi Ye, Chen Zhao, Yezhou Yang, Cornelia Fermuller, Yiannis Aloimonos

LightNet is a lightweight, versatile and purely Matlab-based deep learning framework.

What Can I Do Around Here? Deep Functional Scene Understanding for Cognitive Robots

no code implementations29 Jan 2016 Chengxi Ye, Yezhou Yang, Cornelia Fermuller, Yiannis Aloimonos

For robots that have the capability to interact with the physical environment through their end effectors, understanding the surrounding scenes is not merely a task of image classification or object recognition.

Sparse Norm Filtering

no code implementations17 May 2013 Chengxi Ye, DaCheng Tao, Mingli Song, David W. Jacobs, Min Wu

Optimization-based filtering smoothes an image by minimizing a fidelity function and simultaneously preserves edges by exploiting a sparse norm penalty over gradients.

Spectral Graph Cut from a Filtering Point of View

no code implementations20 May 2012 Chengxi Ye, Yuxu Lin, Mingli Song, Chun Chen, David W. Jacobs

In this paper, we analyze image segmentation algorithms that are based on spectral graph theory, e. g., normalized cut, and show that there is a natural connection between spectural graph theory based image segmentationand and edge preserving filtering.
