1. CALLip: Lipreading using Contrastive and Attribute Learning

Lipreading, aiming at interpreting speech by watching the lip movements of the speaker, has great significance in human communication and speech understanding. Although has reached a feasible performance, lipreading still faces two crucial …

2. Towards Computational Analytics of 3D Neuron Images using Deep Adversarial Learning

Benefited from advances of neuron tracing techniques, the ever-increasing number of digitally reconstructed 3D neuron images have greatly facilitated the research in neuromorphology. However, the sheer volume and the complexity of these 3D neuron …

3. Piecewise Flat Embedding for Image Segmentation

We introduce a new multi-dimensional nonlinear embedding, Piecewise Flat Embedding (PFE), for image segmentation. Based on the theory of sparse signal recovery, piecewise flat embedding with diverse channels attempts to recover a piecewise constant …

4. Deep Feature Representation for The Computational Analytics of 3D Neuronal Morphology

With the ever-increasing number of digitally reconstructed neurons, computational analytics of 3D neuronal morphology has become a new avenue to understand neuroanatomical structures and functional properties. However, traditional methods cannot well …

5. Piecewise Flat Embedding for Image Segmentation

Image segmentation is a critical step in many computer vision tasks, including high-level visual recognition and scene understanding as well as low-level photo and video processing. In this paper, we propose a new nonlinear embedding, called …
