Fast adaptive upscaling of low structured images using a hierarchical filling strategy
- Trang 289-293
Image upscaling approaches are required especially when algorithms are applied
to subsampled images in order to speed up processing time. Conventional
techniques for upscaling images yield often blurred or blocky results, but more
complicated methods are time consuming. We present an adaptive upscaling
approach for low structured images, which provides real time capability for
images in full TV re...

Multiple narrow-baseline system for immersive teleconferencing
- Trang 367-370
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...

A robust video watermarking technique in the spatial domain
- Trang 251-256
We present a scheme for robust watermark insertion into video sequences. The
proposed approach works in the uncompressed image domain, and it is robust
against a large set of possible attacks. It has been developed for two principle
applications: copyright protection and invisible embedding of indexing
information. The proposed scheme has been tested and the results show that a
robust watermark ca...

Image segmentation and classification using color features
- Trang 57-64
Color provides a wealth of information for interpretation of image content. The
increased availability of affordable digital color cameras has created the
opportunity to explore the degree to which color is useful in computer vision.
This paper shows that a system for image segmentation and classification can be
created using color as the primary feature. This system is comprised of two
phases: se...

Hệ thống giám sát video chủ động qua Internet Dịch bởi AI
- Trang 221-226
Chúng tôi đã thiết kế một hệ thống với giao diện người dùng trực quan cho việc
điều khiển camera từ xa và truy vấn hình ảnh qua Internet. Trong quá trình tìm
kiếm các giải pháp hiện có, chúng tôi nhận ra tầm quan trọng của một giao diện
người dùng được thiết kế tốt. Chúng tôi đã phát triển một hệ thống, cho phép
quan sát từ xa và điều khiển camera mạng JVC qua Internet. Giao diện người dùng

Adaptive interface for hypermedia applications
- Trang 147-152
In the paper a concept for adaptive construction of the user interfaces of
multiplatform hypermedia applications is presented. The user interface is
becoming the crucial element of every information system and as the users as
well as platforms are very differentiated it is difficult to construct a single
equally efficient interface for all of these cases. Adaptive interfaces with
social perspectiv...

Another generalisation of vector filters
- Trang 273-278
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...

Hybrid N-feature extraction with fuzzy integral in human face recognition
- Trang 93-98
This paper introduces an efficient method for human face recognition that
employs a set of different kinds of feature domains with RBF neural network
classifiers, and which is denoted the hybrid N-feature (HNF) human face
recognition. A combination of RBF neural network classifiers with fuzzy integral
has been proposed to achieve face classification with higher performance. The
feature extractor p...

SCAN methodology optimization based on correlation
- Trang 217-220
This paper presents a new scheme for lossless image coding with SCAN image data
scanning (Maniccam et al. (2001)). A methodology for creation of a convenient
space-filling curve based on correlation is introduced.

On "slant-like" fast orthogonal transforms of arbitrary order
- Trang 309-314
A concept for the construction of fast orthogonal transforms with matrices
containing one or more predefined rows is proposed. In particular, two new
families of "slant-like" transforms with matrices of arbitrary orders, including
a constant row and a slant row of arbitrary slanting angle, are introduced.
Transforms from these families may be computed with fast regular algorithms
suitable for para...
