OVERVIEW OF DIGITAL FORENSICS ALGORITHMS IN DSLR CAMERAS
DSLR cameras digital image forensics fixed pattern noise hot pixel flat field
2017/5/15
The widespread usage of the mobile technologies and the improvement of the digital photo devices getting has led to more frequent cases of falsification of images including in the judicial practice. C...
A fusion of algorithms in near duplicate document detection
duplicate document detection digital library web pages near duplicate document
2011/7/12
With the rapid development of the World Wide Web, there are a huge number of fully or fragmentally duplicated pages in the Internet. Return of these near duplicated results to the users greatly affect...
Breast Tumor Simulation and Parameters Estimation Using Evolutionary Algorithms
Breast Tumor Simulation Parameters Estimation Evolutionary Algorithms
2009/9/4
An estimation methodology is presented to determine the breast tumor parameters using the surface temperature profile that may be obtained by infrared thermography. The estimation methodology involves...
Bounded cost algorithms for multivalued consensus using binary consensus instances
Distributed computing Fault tolerance Binary consensus Multivalued consensus
2009/8/18
In this paper, we present two bounded cost algorithms that solve multivalued consensus using binary consensus instances. Our first algorithm uses log2 n number of binary consensus instances where n ...
A DISTORTION INPUT PARAMETER IN IMAGE DENOISING ALGORITHMS WITH WAVELETS
Signal Processing denoising filtering
2009/1/1
The problem of image denoising based on wavelets is considered. The paper
proposes an image denoising method by imposing a distortion input parameter instead
of threshold. The method has two algorit...
ESTIMATING THE VALUE OF θ IN THE INTRA FRAME FOR ρ-DOMAIN RATE CONTROL ALGORITHMS
ρ-domain Rate Control θ Estimation
2006/5/16
The ρ-domain rate control algorithm is very simple and effective. There is only one parameter, θ, used in the model. θ reflects the relationship between the rate and the quantization step. Accur...
Advanced Very Low Bit Rate Video Coding Using Preferential Pattern Selection Algorithms
Very Low Bit Rate Video Coding Preferential Pattern Selection Algorithms
2004/5/17
In the context of very low bit-rate video coding, pre-defined fixed pattern representations of moving regions in blocked-based motion estimation and compensation has become increasingly attractive ove...
