Attacks on Recent RFID Authentication Protocols
Journal of Signal Processing Systems - Tập 79 - Trang 271-283 - 2013
The developing of RFID systems in sensitive applications like e-passport, e-health, credit cards, and personal devices, makes it necessary to consider the related issues such as maximum reading distance, communication speed and data security. The use of signal processing methods is an efficient and convenient way to achieve the maximum reading distance and communication rate. However, the signal p...... hiện toàn bộ
A Parametrizable High-Level Synthesis Library for Accelerating Neural Networks on FPGAsAbstract In recent years, Convolutional Neural Network CNN have been incorporated in a large number of applications, including multimedia retrieval and image classification. However, CNN based algorithms are computationally and resource intensive and therefore difficult to be used in embedded systems. FPGA based accelerators are becoming more and more popular in res... ... hiện toàn bộ

Robust Periocular Recognition by Fusing Sparse Representations of Color and Geometry Information
Journal of Signal Processing Systems - Tập 82 - Trang 403-417 - 2015
In this paper, we propose a re-weighted elastic net (REN) model for biometric recognition. The new model is applied to data separated into geometric and color spatial components. The geometric information is extracted using a fast cartoon - texture decomposition model based on a dual formulation of the total variation norm allowing us to carry information about the overall geometry of images.

GPU-Based Iterative Medical CT Image Reconstructions
Journal of Signal Processing Systems - Tập 91 - Trang 321-338 - 2018
The algebraic reconstruction technique (ART) is an iterative algorithm for CT (i.e., computed tomography) image reconstruction that delivers better image quality with less radiation dosage than the industry-standard filtered back projection (FBP). However, the high computational cost of ART requires researchers to turn to high-performance computing to accelerate the algorithm. Alas, existing appro...... hiện toàn bộ
Digit-Serial Pipeline Sorter Architecture
Journal of Signal Processing Systems - Tập 61 - Trang 241-249 - 2009
This paper presents the VLSI architecture design of pipeline sorter which is suitable for the fast sorting of the continuous serial input data stream. By decomposing the Batcher’s merge-sort process into a network of compare-and-swap (C&S) operations, two different styles of pipeline architectures based on the feedback and feed-forward data shuffling modules can be first achieved. However, both ar...... hiện toàn bộ
A High Capacity Spatial Domain Data Hiding Scheme for Medical Images
Journal of Signal Processing Systems - Tập 87 - Trang 215-227 - 2016
This paper presents a spatial steganography scheme with high steganography capacity for medical images. In the proposed scheme, four least significant bits of the cover image are used to hide secret information and a logistic mapping is employed to scramble cover image before embedding operation. In order to achieve minor degradation to cover medical image, the ROI region is excluded manually befo...... hiện toàn bộ
New Algorithms for the Estimation of Two-Dimensional Cyclic Spectral Information Based on Tensor Equations
Journal of Signal Processing Systems - Tập 93 - Trang 677-687 - 2021
The hidden periodicity detection using a cyclic spectral function (CSF) is one of the well-known methods for cyclostationary signals analysis. Many two-dimensional signals (2D-signals), such as textures, can be considered cyclostationary or semi-cyclostationary. Applying such an assumption provides a new effective field for the analysis of 2D-signals. This paper presents two new algorithms for two...... hiện toàn bộ
Hardware-Software Implementation of a Sensor Network for City Traffic Monitoring Using the FPGA- and ASIC-Based Sensor Nodes
Journal of Signal Processing Systems - Tập 71 - Trang 57-73 - 2012
This paper presents a prototype sensor network for monitoring urban traffic. The sensor network node, equipped with a low-resolution camera, observes the street and detects moving objects. Object detection is based on the custom video segmentation algorithm, using dual background subtraction, edge detection and shadow detection, running on dedicated multi-processor SoC hardware. The number and the...... hiện toàn bộ
Investigation of Weighted Least Squares Methods for Multitarget Tracking with Multisensor Data Fusion
Journal of Signal Processing Systems - - 2023
Target localization in a wireless sensor network (WSN) has received more and more attention in recent years, and has promoted many new applications due to the low cost, low bandwidth, low energy consumption, and collision avoidance mechanism. How to provide accurate location information has always been a hot research topic in 5G/B5G application scenarios. In this paper, the path loss information o...... hiện toàn bộ
Hệ thống Watermark Ảnh Thích Ứng Sử Dụng Entropy Mờ và Tổ Hợp GA-ELM Trong Miền DCT Để Bảo Vệ Bản Quyền Dịch bởi AI
Journal of Signal Processing Systems - Tập 84 - Trang 265-281 - 2015
Bài báo này đề xuất một hệ thống watermark ảnh mới với tính năng bán mù dựa trên entropy mờ và thuật toán di truyền (GA) – tổ hợp máy học cực đoan (ELM) trong miền biến đổi Cosine rời rạc (DCT) nhằm bảo vệ bản quyền. Việc chọn các khối không chồng chéo để nhúng watermark nhị phân dựa trên entropy mờ. Do entropy mờ có khả năng phân biệt phân phối dữ liệu trong điều kiện bị nhiễu và dư thừa, việc tr...... hiện toàn bộ
