The Heisenberg Uncertainty principle is a fundamental concept from Quantum Mechanics that also describes the Fourier Transform. Unfortunately, it does not directly apply to the digital signals. However, it can be generalized if we use...
In order to better study how to improve the accuracy of texture recognition in image processing, we will study the concept of information entropy, which characterizes the uncertainty of the information source. Since the information...
The CS technology has attracted considerable attention because it can surpass the traditional limit of Nyquist sampling theory. Rather than sampling a signal at a high frequency and then compressing it, the CS senses the target signal in...
The term \textit{compactness} refers to the notion of joint localization used to describe a signal that is simultaneously efficient in the time and frequency domains. Traditional methods based on the Heisenberg-Weyl measure only quantify...
As a natural scarcity in wireless networks, radio spectrum becomes a major investment in network deployment. How to improve the channel utilization (CU) of the spectrum is a challenging topic in recent research. In a network environment, ...
Object detection is an important part of the image processing system, especially for applications like Face detection, Visual search engine, counting and Aerial Image analysis. Hence the performance of object detectors plays an important...
Digital Signal Processing (DSP) performs a very important role in various applications of electrical engineering like communications and signal enhancement. In many situations one finds that the DSP hardware available are fixed point...
Emergency message dissemination (EMD) in vehicular ad hoc network (VANET) becomes a hot topic due to the ever increasing concern on the road safety. When encountering unusual situations, emergency messages should be disseminated quickly...
