IEEE International Conference on Image Processing
作者: Meng Pang Chuang Lin Risheng Liu Xin Fan Jifeng Jiang Zhongxuan Luo School of Software Dalian University of Technology
Over the past few decades, matrix factorization has attracted considerable attention for image representation. It is desired for a matrix factorization technique to find the basis that is able to capture highly discri... 详细信息

IEEE Conference on Computer Vision and Pattern Recognition
作者: Louise Benoit Julien Mairal Francis Bach Jean Ponce Ecole Normale Superieure INRIA
sparse coding, which is the decomposition of a vector using only a few basis elements, is widely used in machine learning and image processing. The basis set, also called dictionary, is learned to adapt to specific da... 详细信息

Annual Conference on Neural Information Processing Systems
作者: Xiaofeng Ren Liefeng Bo Intel Science and Technology Center for Pervasive Computing Intel Labs Seattle WA 98195 USA
Finding contours in natural images is a fundamental problem that serves as the basis of many tasks such as image segmentation and object recognition. At the core of contour detection technologies are a set of hand-des... 详细信息

IEEE International Conference on Acoustics, Speech and Signal Processing
作者: Rameswar Panda Amit K. Roy-Chowdhury Electrical and Computer Engineering Department University of California Riverside United States of America
While most existing video summarization approaches aim to extract an informative summary of a single video, we propose an unsupervised framework for summarizing topic-related videos by exploring complementarity within... 详细信息

Annual Conference on Neural Information Processing Systems
作者: Junyuan Xie Linli Xu Enhong Chen School of Computer Science and Technology University of Science and Technology of China
We present a novel approach to low-level vision problems that combines sparse coding and deep networks pre-trained with denoising auto-encoder (DA). We propose an alternative training scheme that successfully adapts D... 详细信息

Annual Conference on Neural Information Processing Systems
作者: Ioannis Gkioulekas Todd Zickler Harvard SEAS Cambridge MA 02138
We propose an approach for linear unsupervised dimensionality reduction, based on the sparse linear model that has been used to probabilistically interpret sparse coding. We formulate an optimization problem for learn... 详细信息

IEEE International Conference on Image Processing
作者: Fang Yin Xiujuan Chai Yu Zhou Xilin Chen Key Lab of Intelligent Information Processing of Chinese Academy of Sciences (CAS) Institute of Computing Technology CAS Institute of Information Engineering Chinese Academy of Sciences
In this paper, a sparse coding based framework is proposed for sign language recognition (SLR), especially for the signer-independent case. To deal with the inter-signer variation, a dictionary capturing the common fe... 详细信息
