IEEE Statistical Signal Processing Workshop (SSP)
作者: Wang, Ren Liao, Xuejun Guo, Jingbo Tsinghua Univ Dept Elect Engn Beijing 100084 Peoples R China Duke Univ Dept Elect & Comp Engn Durham NC 27708 USA
Gaussian mixture models (GMM) have been used to statistically represent patches in an image. Extending from small patches to an entire image, we propose a convolutional Gaussian mixture models (convGMM) to model the s... 详细信息

sparse Overcomplete Denoising: Aggregation Versus Global Optimization
收藏 引用
IEEE SIGNAL PROCESSING LETTERS 2017年 第10期24卷 1468-1472页
作者: Carrera, Diego Boracchi, Giacomo Foi, Alessandro Wohlberg, Brendt Politecn Milan I-20133 Milan Italy Tampere Univ Technol Tampere 33720 Finland Los Alamos Natl Lab Los Alamos NM 87545 USA
Denoising is often addressed via sparse coding with respect to an overcomplete dictionary. There are two main approaches when the dictionary is composed of translates of an orthonormal basis. The first, traditionally ... 详细信息

IEEE International Conference on Acoustics, Speech and Signal Processing
作者: Brendt Wohlberg Theoretical Division Los Alamos National Laboratory Los Alamos NM 87545 USA
While convolutional sparse representations enjoy a number of useful properties, they have received limited attention for image reconstruction problems. The present paper compares the performance of block-based and con... 详细信息
