Digital video contents now become easily available through Internet and various medium. Easy availability made digital video more popular than analog media. And it attains a sharp attention regarding its ownership. The ownership integrity can be easily violated using different video editing software. In this regard we are proposing a chip level framework in accordance with our already proposed LSB...
The current explosion of digital media creates threats towards the security in multimedia data broadcasting. Watermarking technique becomes a prospective solution to this coercion by means of Intellectual Property Right Protection, Authentication and Integrity Verification of digital media. In this paper we introduce an approach that enables us to develop a low power, real time, reliable and secure...
Image authentication has achieved a sharp attention now a day due to broad availability of Internet services. Maldistribution and illegal copying of image, volatiles the authenticity of image-ownership. In this regard we have already proposed different fragile color image watermarking frameworks for embedding a color watermark within a color host image. In current communication we are proposing technique...
Easy availability of internet, together with relatively inexpensive digital recording and storage peripherals has created an era where duplication, unauthorized use and maldistribution of digital content has become easier. To prevent unauthorized use, misappropriation, misrepresentation; authentication of multimedia contents achieved a broad attention in recent days. In this regard we've already introduced...
In remote sensing systems one of the most important features needed are roads, which require automated procedures to rapidly identify them from high-resolution satellite imagery, Many approaches for automatic road extraction have appeared in literature , which vary due to the differences in their goals, available information, algorithms used and assumptions about roads. In this paper, we propose an...
Ownership authentication of image attended a careful attention due to global availability of internet services. Illegal copying and misappropriation of digital image leads cyber crime in an epidemic form. In aforesaid regard we've already proposed different fragile color image authentication schemes which guarantees ownership of an image through embedding color watermarks into color host images. In...
Particle swarm optimization (PSO) has recently emerged as a simple yet very efficient algorithm for global optimization over continuous spaces. This article describes the application of an improved variant of PSO to the segmentation of objects from complicated real life images. The segmentation task amounts to finding a robust and optimal threshold that separates an object from a background frame...
Image understanding concerns the issues of how to facilitate interpretation of images. The work reported here is in support of a novel approach for machine interpretation of soil chromatograms. A chromatogram image is obtained from an alkaline solution of silver nitrate and soil. The patterns in the chromatogram contain information of mineral contents in the soil. We describe a combination of different...
This article presents an algorithm for the automatic detection of circular shapes from complicated and noisy images. The algorithm is based on a hybrid technique composed of simulated annealing and differential evolution. A new fuzzy objective function has been derived for the edge map of a given image. Minimization of this function with a hybrid annealed differential evolution algorithm leads to...
A modified differential evolution (DE) algorithm is presented for clustering the pixels of an image in its intensity space. The algorithm requires no prior information about the number of naturally occurring clusters in the image. It employs a kernel-induced similarity measure instead of the conventional sum-of-squares distance. Use of the kernel function makes it possible to partition data that is...
