An Adaptive Source-Channel Coding with Feedback for Progressive Transmission of Medical Images

open access: yesInternational Journal of Telemedicine and Applications, 2009
A novel adaptive source-channel coding with feedback for progressive transmission of medical images is proposed here. In the source coding part, the transmission starts from the region of interest (RoI).

Twofold dynamic attention guided deep network and noise-aware mechanism for image denoising

open access: yesJournal of King Saud University: Computer and Information Sciences, 2023
Convolutional neural networks are given extensive attention towards noise removal due to their good performance over traditional denoising algorithms. With shallow conventional neural networks, the feature extraction ability is not profound.

Cyclic LTI systems in digital signal processing [PDF]

open access: yes, 1999
Cyclic signal processing refers to situations where all the time indices are interpreted modulo some integer L. In such cases, the frequency domain is defined as a uniform discrete grid (as in L-point DFT). This offers more freedom in theoretical as well

A New Method for Building Low-Density-Parity-Check Codes

open access: yesInternational Journal of Technology, 2019
This paper proposes a new method for building low-density-parity-check codes, exempt of cycle of length 4, based on a circulant permutation matrix, which needs very little memory for storage it in the encoder and a dual diagonal structure is applied ...
