A multiple description scalar quantization (MDSQ) based coding system can be regarded as a source coder (quantizer) followed by a channel coder, i.e. the combination of index and codeword assignment. The redundancy, or the correlation between the descriptions, is controlled by the number of diagonals covered by the index assignment. We consider here the usage of multiple description uniform sca...

Progressive mucinous histiocytosis is a very rare, benign, non-Langerhans' cell histiocytosis limited to the skin. In total ten patients (all women) in four families and three sporadic cases have been reported. We report here the first published case of a male patient with progressive mucinous histiocytosis. The multiple red papules on the scalp and forearms were asymptomatic and had slowly inc...

This paper presents a method of progressive transmission of vector data on the web based on the Changes Accumulation Model. The model considers the spatial representation from one scale to another scale as an accumulation of a set of changes, and the change can take place at three levels: layer, object and geometric detail. Taking the example of drainage network, this paper gives a new storage ...

Progressive transmission of images is an important functionality for communicating high resolution images over limited bandwidth networks. By encoding the image data in an accessible and hierarchical format, the JPEG 2000 standard supports many types of image progessions, e.f., based on quality, resolution, component and position. This paper considers a progressive transmission scheme in which ...

With development of biomedical and networking technology, interactive volume rendering with data transmitted via the network becomes an interesting topic. Two technical problems are data transmission and fast volume rendering. In this paper, two schemes using Wavelet foveation are proposed and implemented: the region-based and coarse-to-fine. The first scheme transmits and renders the region of...

It is important to transmit pictures efficiently in most Web sites, especially for those users with low bandwidth connections. In this demonstration, we propose a system which progressively transmits images using a very low transmission rate (as low as 15% in some cases). The transmitted images maintain a reasonable picture quality for the users to browse images quickly. Interested readers can ...

In this paper we propose a fast reconstruction method for a progressive subband-decomposed signal coding system. It is shown that unlike the normal approach which contains a xed computational complexity, the computational complexity of the proposed approach is proportional to the number of reened coeecients. Therefore, using the proposed approach in image coding applications, we can update the ...

In response to the growing need for image analysis services in the cloud computing environment, this paper proposes an automatic system for detecting landmarks in 3D volumes. The inherent problem of limited bandwidth between a (thin) client, Data Center (DC), and Data Analysis (DA) server is addressed by a hierarchical detection algorithm that obtains data by progressively transmitting only ima...

Realtime streaming 3D model over wireless network is a challenging proposition due to the characteristic of 3D progressive geometry data and wireless network. In this paper, we propose a perceptual-driven 3D progressive model selective transmission method. For the progressive model, the data including the base mesh and a series of vertex splits will be packed into several packets. A novel perce...

In the last years several 3D model compression methods for multiresolution applications have been presented, most of them using 3D meshes. Octrees are a natural multiresolution representation scheme, although it is approximate. Extensions of classical Octrees that represent polyhedral object exactly have been proposed. One of them are the SP-Octrees, that incorporates boundary information of th...
