DIGITAL image-coding USING LEGENDRE TRANSFORM
收藏 引用
CIRCUITS SYSTEMS AND SIGNAL PROCESSING 1994年 第1期13卷 3-18页
作者: ELRAYESS, DM GHONIEMY, S BAHGAT, SF 1. Guidance Department M.T.C. Cairo Egypt
image coding can be implemented through DPCM, transform, hybrid, or segmentation coding techniques. Some transform coding techniques, such as cosine and Hadamard, have been exhaustively analyzed and evaluated, while o... 详细信息

IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY 2014年 第11期24卷 2004-2010页
作者: Sun, Yipeng Tao, Xiaoming Li, Yang Lu, Jianhua Tsinghua Univ Dept Elect Engn Beijing 100084 Peoples R China
In this brief we propose a multisample sparse representation (MSR)-based online dictionary-learning approach to encode images more efficiently. To minimize the reconstructed error while handling a variety of image sam... 详细信息

Conference on image Processing - Algorithms and Systems II
作者: Vasilache, A Tabus, I Tampere Univ. of Technology (Finland)
This paper presents an image coding method, based on wavelet transform, where the distribution of the subband coefficients is assumed to be generalized Gaussian. The shape factor and the standard deviation are estimat... 详细信息

PROCEEDINGS OF THE IEEE 1995年 第2期83卷 272-287页
作者: EGGER, O LI, W KUNT, M Signal Processing Laboratory Swiss Federal Institute of Technology Lausanne Switzerland
In this paper a morphological subband decomposition with perfect reconstruction is proposed. Critical subsampling is achieved. Reconstructed images using this decomposition do not suffer from any ringing effect. In or... 详细信息
