Study on transforming from painting to music
International Symposium on VIPromCom Video/Image Processing and Multimedia Communications - - Trang 117-120
Xia Mao, Bin Chen, Gang Zhu, T. Hoshino
This paper aims at probing into the mapping relationship and rules between painting and music. After the examination of corresponding relation between image and music, relevant arithmetic is put forward in accordance with certain principles in scientific and art, in which the original information in the image is converted into musical information, thus enabling people to obtain visual impression f...... hiện toàn bộ

DVB-MHP transport stream generator
International Symposium on VIPromCom Video/Image Processing and Multimedia Communications - - Trang 453-456
R. Rodriguez, A. Gil, A. Fernandez, R. Diaz, M. Fernandez, J. Garcia
We present superficially a software tool - a DVB-MHP (digital video broadcasting multimedia home platform) compliant transport stream generator /sub e/signed to be part of the testbed of an MHP decoder prototype. The tool was implemented partially making use of XML technology and the software reuse philosophy (freely-distributed parsers and tools) that, in a sense, goes with this special syntax.

Combating geometrical attacks in a DWT based blind video watermarking system
International Symposium on VIPromCom Video/Image Processing and Multimedia Communications - - Trang 263-266
C.V. Serdean, M.A. Ambroze, M. Tomlinson, G. Wade
This paper describes a high capacity blind video watermarking system invariant to geometrical attacks such as shift, rotation, scaling and cropping. A spatial domain reference watermark is used to obtain invariance to geometric attacks by employing image registration techniques to determine and invert the attacks. A second, high capacity watermark, which carries the data payload, is embedded in th...... hiện toàn bộ

Multiple narrow-baseline system for immersive teleconferencing
International Symposium on VIPromCom Video/Image Processing and Multimedia Communications - - Trang 367-370
E. Cooke, P. Kauff, O. Schreer
An important aim of immersive teleconferencing systems is to create realistic 3D virtual views of remote conferees. Hence, systems should be able to deal with hand gestures as well as occluded areas in reference images required in derived views. The quality of such derived views is dependent not only on the analysis and synthesis process but also the multiview camera set-up. Often the popular conv...... hiện toàn bộ

Color-space analysis for facial feature detection
International Symposium on VIPromCom Video/Image Processing and Multimedia Communications - - Trang 83-86
H. Demirel
Facial feature detection is an important preprocessing step used in facial image processing. Most of the image-based facial feature detection techniques use only the luminance information ignoring the color information of the images. We introduce a method of adding color-space information to the principal component analysis (PCA) based eigen features technique. The experimental results show that t...... hiện toàn bộ

Another generalisation of vector filters
International Symposium on VIPromCom Video/Image Processing and Multimedia Communications - - Trang 273-278
R. Lukac
A new generalisation of vector filters utilising the ordering of vector samples is provided. According to a distance function based on vector distances and vector angles, it is possible to differentiate vector median filters (VMFs), vector directional filters (VDFs) and finally directional distance filters (DDFs) that combine both distance and angles of vector samples in the vector space. For that...... hiện toàn bộ

Scale correlation-based edge detection
International Symposium on VIPromCom Video/Image Processing and Multimedia Communications - - Trang 345-350
P. Bao, Lei Zhang
This paper proposes an effective edge detection scheme based on the scale correlation in the wavelet transform that is equivalent to Canny edge detection. A correlation function is defined as the product of two adjacent wavelet subbands to magnify edges while filtering noise. Unlike many multi-scale techniques that form the edge maps on different scales and then synthesize them into a spatial edge...... hiện toàn bộ

Experiences from implementing a MHP receiver
International Symposium on VIPromCom Video/Image Processing and Multimedia Communications - - Trang 441-446
J.C. Lopez-Ardao, C. Lopez, A. Gil, R. Diaz, A. Fernandez, M. Fernandez, A. Suarez, J. Munoz
The growth of interactive digital TV heralds a seamless convergence of media, telecommunications, and information technology, offering viewers increasingly exciting and interactive programming. The need of standardization in this field led DVB to head the regulator project, defining standards for digital video broadcasting and interactive services in all transmission networks, and recently for a g...... hiện toàn bộ

Use of area-closing to improve granulometry performance
International Symposium on VIPromCom Video/Image Processing and Multimedia Communications - - Trang 303-308
K.N.R. Mohana Rao, A.G. Dempster
We present a new procedure for computing the granulometry function. Computation of granulometry is normally done by morphological opening/closing performed on an image with structuring elements of increasing size. This can pose problems, if pixels within the image components are not nearly uniform gray level (or have large variations) or if there are patches within the objects of interest. The pro...... hiện toàn bộ
