Abstract

Image segmentation consists of dividing an image domain into disjoint regions according to a characterization of the image within or in-between the regions. Therefore, segmenting an image is to divide its domain into relevant components. The efficient solution of the key problems in image segmentation promises to enable a rich array of useful applications. The current major application areas include robotics, medical image analysis, remote sensing, scene understanding, and image database retrieval. The subject of this book is image segmentation by variational methods with a focus on formulations which use closed regular plane curves to define the segmentation regions and on a level set implementation of the corresponding active curve evolution algorithms. Each method is developed from an objective functional which embeds constraints on both the image domain partition of the segmentation and the image data within or in-between the partition regions. The necessary conditions to optimize the objective functional are then derived and solved numerically. The book covers, within the active curve and level set formalism, the basic two-region segmentation methods, multiregion extensions, region merging, image modeling, and motion based segmentation. To treat various important classes of images, modeling investigates several parametric distributions such as the Gaussian, Gamma, Weibull, and Wishart. It also investigates non-parametric models. In motion segmentation, both optical flow and the movement of real three-dimensional objects are studied.

Abstract

The book reflects the state of the art in important areas of speech and audio signal processing. It presents topics which are missed so far and most recent findings in the field. Leading international experts report on their field of work and their new results. Considerable amount of space is covered by multi-microphone systems, specific approaches for noise reduction, and evaluations of speech signals and speech processing systems. Multi-microphone systems include automatic calibration of microphones, localisation of sound sources, and source separation procedures. Also covered are recent approaches to the problem of adaptive echo and noise suppression. A novel solution allows the design of filter banks exhibiting bands spaced according to the Bark scale und especially short delay times. Furthermore, a method for engine noise reduction and proposals for improving the signal/noise ratio based on partial signal reconstruction or using a noise reference are reported. A number of contributions deal with speech quality. Besides basic considerations for quality evaluation specific methods for bandwidth extension of telephone speech are described. Procedures to reduce the reverberation of audio signals can help to increase speech intelligibility and speech recognition rates. In addition, solutions for specific applications in speech and audio signal processing are reported including, e.g., the enhancement of audio signal reproduction in automobiles and the automatic evaluation of hands-free systems and hearing aids.

Abstract

Digitale Signaalverwerking (Digital Signal Processing, DSP) is een van de snelst groeiende terreinen in de moderne elektronica en de motor achter vele ontwikkelingen in de telecommunicatie en andere gebieden. Jammergenoeg heeft DSP de reputatie gepaard te gaan met gecompliceerde wiskunde en ingewikkelde theorie. Voor technici of studenten, op zoek naar het verwerven van nieuwe kennis over DSP ontwerpen, valt het vaak niet mee om praktijkgerichte, stap voor stap informatie te vinden. &#13;&#13;Verder zoeken hoeft niet meer. Jim Broesch is een technicus die de behoefte aan een snelle introductie in DSP begrijpt. Zijn boek breekt het onderwerp in gemakkelijk te begrijpen delen en geeft vanzelfsprekende, praktische uitleg van de belangrijkste begrippen. Bovendien zorgt de bijgeleverde DSP Calculator software voor dynamische demonstraties van de geleerde begrippen uit de tekst. Het is een virtueel laboratorium; om met basis-DSP te experimenteren. Binnen de kortste keren ontwerpt men digitale filters! &#13;&#13;Wat kan men tegenkomen: &#13;&#13;- Een duidelijk model van een algemeen DSP-systeem &#13;- De wiskunde achter DSP-ontwerpen, uitgelegd in begrijpelijke taal. &#13;- De principes van periodieke bemonstering beschreven in gewoon Nederlands. &#13;- Een heldere inleiding tot de discrete Fourier transformatie, Fast Fourier transformatie en andere belangrijke hulpmiddelen. &#13;- Uitgebreide informatie over de belangrijke FIR en IIR digitale filters. &#13;- Een praktische en informatieve uitleg over bundeling en het gebruik ervan. &#13;- Toepassingen, aanwijzingen, en kneepjes van het vak &#13;- En nog veel meer!&#13;&#13;

Abstract

This book systematically addresses the quantification of quality aspects of multimodal interactive systems. The conceptual structure is based on a schematic view on human-computer interaction where the user interacts with the system and perceives it via input and output interfaces. Thus, aspects of multimodal interaction are analyzed first, followed by a discussion of the evaluation of output and input and concluding with a view on the evaluation of a complete system.
