Time-Recursive Computation, Part II: Methodology, and Application on QMF Banks and ELT
(1993)
Recent advances in ISDN have promoted applications such as video- phone, tele-conferencing and HDTV, that demand real-time processing of large volume audio, video and speech data. Being the only refuge for this intense ...
Fractal Modeling and Segmentation for the Enhancement of Microcalcifications in Digital Mammograms
(1996)
The objective of this research is to model the mammographic parenchymal, ductal patterns and enhance the microcalcifications using deterministic fractal approach. According to the theory of deterministic fractal geometry, ...
Subband Coded Image Transmitting over Noisy Channels Using Multicarrier Modulation
(1998)
In this paper, we present a new loading algorithm for subband coded image transmission on multicarrier modulation systems. The image subbands are transmitted simultaneously, each occupying a number of subchannels. Different ...
Image and Video Transmission over Wireless Channels: A Subband Modulation Approach
(1998)
A new approach of reliable image and video transmission over wireless channels is proposed. The subband modulation which combines source coding and channel modulation schemes achieves high compression efficiency and ...
Wavelet-Based Multiresolution Local Tomography
(1995)
We develop an algorithm to reconstruct the wavelet coefficients of an image from the Radon transform data. The proposed method uses the properties of wavelets to localize the Radon transform and can be used to reconstruct ...
Split Recursive Least Squares: Algorithms, Architectures, and Applications
(1994)
In this paper, a new computationally efficient algorithm for recursive least-squares (RLS) filtering is presented. The proposed Split RLS algorithm can perform the approximated RLS with O(N) complexity for signals having ...
Time-Recursive Computation and Real-Time Parallel Architectures, Part I: Framework
(1993)
The time-recursive computation has been proved as a particularly useful tool in real-time data compression, in transform domain adaptive filtering and in spectrum analysis. Unlike the FFT based ones, the time-recursive ...
Exact Subpixel Motion Estimation in DCT Domain
(1996)
Currently existing subpixel motion estimation algorithms require interpolation of inter-pixel values which undesirably increases the overall complexity and data flow and deteriorates estimation accuracy. In this paper, we ...
