    This article analyses possibilities of preparing input image data to achieve high compression ratio by using edge enhancing diffusion image compression (EEDC). In this process without data transformation high compression ratio cannot be achieved with entropy coder (range coding in this case). Input data analysis and preparation for entropy coding can reduce the number of bits needed for the compre... View full abstract»

    SVC (scalable video coding) was introduced as an amendment of H.264/AVC by Moving Picture Experts Group (MPEG) and ITU-T Video Coding Experts Group (VCEG) in 2007. SVC can provide different types of scalability and retain reconstruction quality characteristics similar to single layer H.264/AVC but in trade of higher complexity of the decoder compared to H.264/AVC. This paper presents an overview o... View full abstract»

    The lack of publicly available video quality databases motivated us to create two new free available video quality databases, ETFOS CIF Video Quality (ECVQ) database and ETFOS VGA Video Quality database. They differ in resolution (CIF, VGA) and content type. Each database contains 90 videos distorted with H.264/AVC and MPEG-4 Part compression. The overall subjective scores for both databases are c...

    In invasive diagnostics and therapy, especially in microsurgery, there is a trend towards miniaturization of medical devices to keep operative invasion at a minimal level. This affects endoscopic systems in particular: Endoscopic video recordings or live-feeds during operation become more prone to interference by shaking due to continuous miniaturization of the endoscopes, with increasing difficul...

    Organic Light Emitting Diodes (OLED) are a different type of solid-state lighting source. An OLED device is typically formed in a sheet with emissive organic layer(s) located between a cathode and anode and deposited on a substrate. The substrate can be rigid such as glass or metal or flexible using a polymer plastic. The number of emissive layers depends on the desired light output of the device.... View full abstract»

    Display system calibration is of great significance to assure perceptual uniformity. Nevertheless, due to differences in technology and purpose, same colors do not represent precisely the same on different display systems. The goal of this paper is to verify this mismatch and quantify it, aiming at achieving a correlation between displays' technology, purpose and reproduction accuracy. Five modern...

    According to the latest Internet usage statistics, more than 4.5 million photos are being uploaded to Flickr every day. An automated system that can provide feedback about aesthetic value or quality based on learned rules could be a very useful support in picture searching, sorting and editing. This is a challenging problem as it requires semantic understanding of images, which is beyond the state... View full abstract»

    This paper describes the approach used to detect hand postures in computationally undemanding manner. The approach employs some features of the Microsoft Kinect sensor and applies simple geometric calculations and simplifications to effectively detect static hand gestures in real time and under changing lighting and background conditions. The results are further applicable to dynamic gesture recog... View full abstract»

    This paper presents a new solution for human-computer interaction that utilizes hand gestures for intuitive operation without any devices restraining the hand freedom. The proposed system is able to completely replace a mouse as a pointing device. Moreover, it extends mouse capabilities by a set of hand gestures. The system is a vision-based interface, and a simple webcam is sufficient for proper ... View full abstract»

    Surveillance systems frequently use fixed or semimobile cameras. However, in many cases, the use of intelligent mobile sensors is preferrable over fixed sensors, because the system configuration can be modified according to particular environmental conditions or adapted to compensate for one or more malfunctioning sensors. This paper proposes a real-time surveillance system based on a mobile senso... View full abstract»

    In this paper, a widely used so-called impulse noise model, which has short duration and high energy, is presented. This type of noise occurs mostly in the over-the-air transmission, such as in standard broadcasting and satellite transmission. The common sources of impulse noise include lightening, industrial machines, faulty or dusty insulation of high-voltage power lines and various unprotected ... View full abstract»

    In the paper introduction of non-MMSE (minimum mean square error) based predictor optimization techniques to adaptive lossless image compression is considered. The proposed cost function is Minkowski distance, being generalization of MMSE and MMAE (minimum mean absolute error). It is proven empirically and explained why MMSE criterion is suboptimal. Then, currently the best lossless image coding m... View full abstract»

    Determining breast density in mammograms is important both in diagnostic and computer-aided detection applications. Knowing the right breast density and having knowledge of changes in breast density could give a hint of a process which started to happen in a patient. Mammograms are projection images and suffer from problem of overlapping tissue which results in possibility of inaccurate detection ... View full abstract»

    Texture analysis and classification is a well researched topic in computer vision. Since textures are captured at arbitrary angles, the derivation of rotation-invariant texture descriptors has received much attention. A group of high performing texture algorithms are based on the concept of local binary patterns (LBP). These algorithms are very efficient as they typically rely solely on local comp...

    While content-based image retrieval (CBIR) has been an active research area over many years, most CBIR techniques operate in the pixel domain even though images are typically stored in compressed form. Consequently, image decoding is required prior to feature calculation leading to a computational overhead that is prohibitive in particular for the case of online retrieval. However, as has been sho... View full abstract»

    In this paper, we present a novel JPEG steganography method with histogram preserving scheme. The embedding is performed in transformation domain of DCT in JPEG file by modification of selected DCT transform coefficients according to modulo function, which allows to extract the secret message without cover-image being present at the receiver side what gives a predisposition of blind steganography ...
