Progressive Image Transmission Using Singular Value Decomposition
(The Eurographics Association, 2004)
There are many progressive image transmission schemes using vector quantization-related schemes, but there are some problems associated with them. First, these schemes need to train a codebook, and this codebook will ...
A Training-Based Method for Reducing Ringing Artifact in BDCT-Encoded Images
(The Eurographics Association, 2004)
The quantization procedure of block-based discrete cosine transform (BDCT) compression (such as JPEG) introduces annoying visual artifact. In this paper, we propose a novel training-based method to reduce the ringing ...
Animating Peer-Level Annotations Within Web-Based Multimedia
(The Eurographics Association, 2004)
The TabletPC is an example of a new generation of user interface device where pen-based manipulation of information is integrated directly into a user s workflow. Using the TabletPC's existing pen and electronic ink systems, ...
A Segmentation Algorithmfor Jacquard Images Based on Mumford-ShahModel
(The Eurographics Association, 2004)
Automatic pattern segmentation of jacquard images is a challenging task due to the complexity of the images. Active contour models have become popular for finding the contours of a pattern with a complex shape. However, ...
A Novel Quadtree-Structured Scheme for Transmitting Chinese Calligraphy Progressively
(The Eurographics Association, 2004)
Progressive image transmission (PIT) techniques are useful in Web applications. A user can get a rough preview of an image and decide if the entire detail of a picture needs to be transmitted, especially when the network ...
A Component-based Authoring Environment for Creating Multimedia-RichMixed Reality
(The Eurographics Association, 2004)
Applications that seek to combine multimedia with Mixed Reality (MR) technologies in order to create multimediarich MR environments pose a challenge to authors who need to provide content for such applications. Founded on ...
Image-based Rendering of the AnisotropicBRDF ofWoven Fabrics
(The Eurographics Association, 2004)
The reflectance of fabric surface is commonly represented by a 4D bidirectional reflectance distribution function (BRDF). To generate the BRDF from measured data by a gonioreflectometer with 2 degrees of freedom of the ...
Estimating Traffic Density Using Sounds of Moving Vehicles
(The Eurographics Association, 2004)
This paper proposed a method for automatically estimating traffic density by using sounds of moving vehicles. The approach is based on the idea of recognition of the temporal variations that appear on the power signals ...
A Chinese Remainder Theorem Oriented Information Hiding Scheme
(The Eurographics Association, 2004)
Steganography is an information hiding technique that conveys secret information in a host signal using a secret method. Only the receivers and senders know the secret information. Many researchers have proposed their own ...
Analysis of Inter-Frame Coding Without Intra Modes in H.264
(The Eurographics Association, 2004)
H.264/AVC is a new international standard for video coding which has great advantage of coding efficiency com-pared with other standards. It can save about 50% bit-rate compared with that of the successful prior coding ...
