International Conference on Information Management and Engineering, ICIME
作者: Joseph Zalaket Department of computer science Université Saint-Esprit de Kaslik Jounieh Lebanon
MOLAP (multidimensional OLAP) systems are storing data as cubes in multidimensional arrays. Data cubes can be sparse, which slows down the performance of MOLAPs and requests useless additional data storage. Many compr... 详细信息

International Conference on Communications and Networking in China (CHINACOM)
作者: Xuqi Zhu Lin Zhang Yu Liu School of Information and Communication Engineering Beijing University of Posts and Telecommunications Beijing China
Multiple nodes sensing the common target is the most popular application of the Wireless Sensor Networks (WSNs). Pure distributed compression of multiple correlated sources has been discussed much in the related liter... 详细信息

Asia and South Pacific Design Automation Conference
作者: Fu-Ching Yang Cheng-Lung Chiang Ing-Jer Huang Department of Computer Science and Engineering National Sun Yat-sen University Taiwan
The post-T/pre-T trace refers to the trace captured before/after a target point is reached, respectively. Real time compression of the post-T trace in a circular buffer is a challenging problem since the initial state... 详细信息

International Conference on Information, Communications and Signal Processing
作者: Ulrich Speidel Department of Computer Science University of Auckland Auckland New Zealand
While Kolmogorov's well-known results show that absolute string complexity is not computable, its estimation is nevertheless of importance in fields such as randomness testing, data compression evaluation, similar... 详细信息

IEEE International Symposium on Circuits and Systems (ISCAS)
作者: Raj S. Katti Ahana Ghosh Department of Electrical and Computer Engineering North Dakota State University Fargo ND USA
In this paper we propose using the compression method, Shannon-Fano-Elias coding, for encryption. Shannon-Fano-Elias codes lend themselves for encryption because code-words depend on the order in which the symbols tha... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: Carlos E. Davila Electrical Engineering Department Southern Methodist University Dallas TX USA
A framework for implementing the forward adaptive Karhunen-Loeve Transform (FAKLT) is described. Unlike backward adaptive methods, FAKLT computes transform coefficients using basis vectors derived from the most recent... 详细信息

Gamut fitting for image composition applications
收藏 引用
IEEE International Conference on Image Processing
作者: Wenxian Yang Jianmin Zheng Jianfei Cai School of Computer Engineering Nanyang Technological University Singapore
Existing digital image composition algorithms neglect the out-of-gamut problem, i.e. some pixel values in a composited image exceed the displayable or printable range. In this paper, we show that the commonly used sol... 详细信息

IEEE International Symposium on Information (IT) in Medicine and Education, ITME
作者: Qunyi Zhou School of Information and Electronic Engineering Zhejiang University of Science and Technology Hangzhou China
Electrocardiogram (ECG) telemedicine is effective way to obtain better clinical service timely. Limited by network and clinical experience, a progressive ECG transmission schema is required. In this paper, a time-doma... 详细信息
