Unified Parallel Lattice Structures for Time-Recursive Discrete Cosine/Sine/Hartley Transforms [PDF]

open access: yes, 1991
The problems of unified efficient computations of the discrete cosine transform (DCT), discrete sine transform (DST), discrete Hartley transform (DHT), and their inverse transforms are considered. In particular, a new scheme employing the time- recursive

Secure image transmission through LTE wireless communications systems

open access: yesEURASIP Journal on Image and Video Processing
Secure transmission of images over wireless communications systems can be done using RSA, the most known and efficient cryptographic algorithm, and OFDMA, the most preferred signal processing choice in wireless communications.

Image Coding With Data-Driven Fast Transforms Based on Approximate Givens Factorizations

open access: yesIEEE Access
In image compression, adaptive transform coding with optimal linear transforms computed from data being coded has been shown to outperform the widely used two-dimensional discrete cosine transform (2D-DCT).

ProSiteHunter: A Unified Framework for Sequence‐Based Prediction of Protein‐Nucleic Acid and Protein‐Protein Binding Sites

open access: yesAdvanced Science, EarlyView.
This study proposed a unified sequence‐based framework for protein binding site prediction, which adopted a tri‐track semantic multi‐source feature fusion strategy to effectively capture diverse macromolecular interaction sites and further improved the accuracy of antibody‐antigen interaction prediction.

Morphological Transform for Image Compression

open access: yesEURASIP Journal on Advances in Signal Processing, 2008
A new method for image compression based on morphological associative memories (MAMs) is presented. We used the MAM to implement a new image transform and applied it at the transformation stage of image coding ...

Pressure‐Induced Drift Artifacts in Stretchable Liquid Metal ThinFilm Electrocardiogram Electrodes

open access: yesAdvanced Science, EarlyView.
A stretchable LM electrode integrated with a strain sensor enables in situ quantitative investigation of drift artifact and skin deformation. This reveals the significance of pressure‐induced drift artifact and its intimate relationship with the skin potential model.

Generalized Systolic Arrays for Discrete Transforms based on Orthonormal Polynomials [PDF]

open access: yes, 2007
Many discrete transforms, such as the discrete cosine transform (DCT), are derived from sets of orthonormal polynomials. These sets of polynomials all possess recursion relationships, derived from a classic identity. In this paper, this recursion is used

Learning Moisture‐Induced Damage From Vision: Diffusion Models for Real‐Time Monitoring of Additive Manufacturing Processes

open access: yesAdvanced Science, EarlyView.
We introduce a vision‐based real‐time monitoring system for additive manufacturing that detects subtle moisture‐induced degradation via a diffusion model‐based framework. The approach enables nondestructive assessment of moisture‐induced damage level and mechanical performance and establishes a practical route toward more intelligent, reliable, and ...
