In the world of social media video processing is very popular. A video signal is the term used to describe any sequence of time varying images. This paper presents the architectures for Video Processing algorithm using softcore processor. This hardware/software co-design platform has been implemented on a Xilinx Virtex-5 FPGA (XUPV5-LX110T). Field Programmable Gate Array (FPGA) offers various r...

The present paper is intended to present a robust multiplicative video watermarking scheme. In this regard, the video signal is segmented into 3-D blocks like cubes, and then, the 3-D wavelet transform is applied to each block. The low frequency components of the wavelet coefficients are then used for data embedding to make the process robust against both malicious and unintentional attacks. Th...

In this paper, an ontology-driven approach for the semantic analysis of video is proposed. This approach builds on an ontology infrastructure and in particular a multimedia ontology that is based on the notions of Visual Information Object (VIO) and Multimedia Information Object (MMIO). The latter constitute extensions of the Information Object (IO) design pattern, previously proposed for refin...

the record of human brain neural activities, namely electroencephalogram (eeg), is generally known as a non-stationary and nonlinear signal. in many applications, it is useful to divide the eegs into segments within which the signals can be considered stationary. combination of empirical mode decomposition (emd) and hilbert transform, called hilbert-huang transform (hht), is a new and powerful ...

This paper presents a real-time, high speed interface for the capture of live analogue video for DSP based video processing applications. The interface makes use of the link ports, which are standard features of general-purpose digital signal processor (DSP). Hence the interface can be used for the different DSPs with minimum customisation. Current technologies for video processing are either b...

A joint approach of resolution enhancement and artifact reduction for MPEG-2 encoded video is proposed in this paper. This new method uses a Unified Metric for Digital Video Processing (UMDVP). The UMDVP is defined based on coding information of MPEG-2 encoded video. It also takes the local scene content into account. Experimental results have demonstrated that the joint approach using the UMDV...

The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...

Existing video plethysmography methods use standard red-green-blue (sRGB) video recordings of the facial region to estimate heart pulse rate without making contact with the person being monitored. Methods achieving high estimation accuracy require considerable signal-processing power and result in significant processing latency. High processing power and latency are limiting factors when real-t...

An inspection of signal processing approach in order to estimate underwater network cardinalities is conducted in this research. A matter of key prominence for underwater network is its cardinality estimation as the number of active cardinalities varies several times due to numerous natural and artificial reasons due to harsh underwater circumstances. So, a proper estimation technique is mandat...
