Today's life of e-citizens relies more and on the "always-on" paradigm. This transformed our lives in a way that it is difficult, sometimes impossible, to deal with day-by-day activities without being 'connected". The technology enable an individual take advantage, best way, Ubiquitous Computing paradigm Mobile Communication fostered by wide adoption smart devices such as mobile phone, smartphones, tablets so on. In this work we investigate possibility reliably sending small file via Short...

Air-borne and space-borne acquired hyperspectral images are used to recognize objects classify materials on the surface of earth. The state art compressor for lossless compression is Spectral oriented Least SQuares (SLSQ) (see [1–7]). In this paper we discuss image compression: show how visualize each band a visualization suggests that an appropriate ordering can lead improvements in process. particular, consider two important distance measures ordering: Pearson’s Correlation Bhattacharyya...

Nowadays microscopy confocal images are becoming more and a fundamental tool for many application fields, including biology, forensic analysis, medicine, industrial research, etc.. Therefore, as it is easy to note, given the contexts in which such have operate, their protection, or at least non alterability, very challenging problem fields. Although these problems deeply felt, state of art does not exist digital watermarking techniques types images. In this paper, we propose novel scheme...

The rapid diffusion of mobile devices (telephones, smart phones, tablets, etc.) has brought new advanced features developed specifically for these devices. For example it is now possible to publish directly the pictures obtained by integrated camera a phone our social network accounts, or image hosting services, etc. It therefore important have tools on that can prove ownership and use them before publishing images. A common approach guarantee digital images videos Digital Watermarking...

Functional Magnetic Resonance Imaging provides researchers with an effective and non-invasive tool to understand cerebral functions correlate them brain activities. With the ever increasing diffusion of Internet such images may be exchanged in several ways, thus allowing new research medical services. On other hand, ensuring security fMRI data becomes a main concern, due special characteristics arising from strict ethics, legislative diagnostic implications. So it is very important prevent...

Functional magnetic resonance imaging (fMRI) provides an effective and noninvasive tool for researchers to understand cerebral functions correlate them with brain activities. In addition, the ever-increasing diffusion of Internet, such images may be exchanged in several ways, allowing new research medical services. On other hand, ensuring security fMRI data becomes a main concern due their special characteristics arising from strict ethics legislative diagnostic implications. Again, risks...

Digital images play an important role in a wide range of medical applications. Several widespread technologies for digital imaging, such as Computed Tomography (CT), Magnetic Resonance (MR), etc., produce three-dimensional images. Data compression, is thus essential to reduce the volume images, permitting their efficient storing along with improvement relative transmission time through Internet or any other ad-hoc systems, like Picture Archiving and Communication System (PACS),...

3-D volumetric medical images, as for example magnetic resonance (MR) and computed tomography (CT) are an important source of digital data that need lossless compression to be stored or transmitted.

Hyperspectral images are widely used in several real-life applications. In this paper, we investigate on the compression of hyperspectral by considering different aspects, including optimization computational complexity order to allow implementations limited hardware (i.e., sensors, etc.). We present an approach that relies a three-dimensional predictive structure. Our structure, 3D-MBLP, uses one or more previous bands as references exploit redundancies among third dimension. The achieved...

Summary Conventional privacy‐enforcement mechanisms, such as encryption‐based ones, are frequently used to prevent third‐party eavesdroppers intercept confidential information exchanged between two or more parties. However, the use of mechanisms can be perceivable and it alerts involved intercepting entities that could devote some effort in trying remove protection, eg, by cracking encryption keys exploiting vulnerabilities technological solution protect data. Sometimes, from security point...

Digital medical images are becoming even more widespread and used in a large variety of applications. Such often stored local repositories need to be transmitted/ received over the network. Therefore, data compression is an essential mechanism adopt for improving transmission time, as well optimize required storage space. However, due clinical relevance such data, lossless techniques almost ever preferred, given that context it not tolerated any loss data. In this work, starting from Medical...

The ability of the DNA microarray images being used in several application domains, such as computer science, medical sciences, biololgy, toxicology, chemistry, ecology, environmental studies and statistics has enabled collaboration among scientists belonging to different research fields. For this reason, use/management may be sometimes controlled by ethical or proprietary rules. In paper, we address problem protection means visible watermarking techniques, where watermark serves a tag...
