Progressive motoneuronopathy (PMN) is an autosomal recessive mouse disease, which is characterized by the development of hind limbs paralysis rapidly progressing to the anterior parts of the body, muscular atrophy, respiratory depression, and death at 6-7 postnatal weeks. Here, we recorded the resting membrane potential (RMP), spontaneous miniature endplate potentials (MEPPs), and quantum conte...

We have shown that wavelet-TCQ image coders can be conngured to support hierarchical and progressive modes analogous to those speciied by the JPEG standard. These modes can be supported with little or no loss in coding eeciency. We have shown that a relatively simple entropy coder combined with a sophisticated quantizer results in a image coder with PSNR performance similar to that achieved usi...

We present an efficient algorithm for progressive transmission of cutting plane data extracted from large scale Computational Field Simulation (CFS) datasets. Since cutting planes are the most frequently-used method for examination of 3D simulation results, efficient compression of both the geometry/topography and the associated field data is important for good visualization performance, especi...

We consider the problem of joint source-channel coding for progressive packetized transmission of an image over a packet-loss network whose packet loss rate is a random variable. We obtain an algorithm for unequal erasure protection which, by design, maintains progressivity.

Lossless image compression with progressive transmission capabilities plays a key role in measurement applications, requiring quantitative analysis and involving large sets of images. This work proposes a wavelet-based compression scheme that is able to operate in the lossless mode. The quantization module implements a new technique for the coding of the wavelet coefficients that is more effect...

Progressive, adaptive and hierarchical modes are desirable image coding features. This paper presents a quadtree-pruning pyramid coding scheme satisfying all these objectives. Pyramid coding is an approach suitable for progressive image tramsmission, where the original image is divided into different levels that correspond to successive approximants of the original one. Starting from the origin...

A Joint source-channel coding (JSCC) scheme for SPIHT coded image transmission over OFDM systems with spatial diversity is proposed where no feedback channel is available. By using diversity techniques, the fading effects can be dramatically decreased and we show that subchannels in OFDM systems are indeed flat Rayleigh fading channels and approach Gaussian noisy channels when the diversity gai...

A number of static and multi-resolution methods have been introduced in recent years to compress 3D meshes. In most of these methods, the connectivity information is encoded without loss of information, but user-controllable loss of information is tolerated while compressing the geometry and property data. All these methods are very efficient at compressing the connectivity information, in some...

In this paper we describe the compression of light field data using 4D nonstandard wavelet decomposition. For progressive transmission, storage, and rendering of the compressed light field data the new wavelet stream data structure is introduced. The wavelet coefficients are ordered in decreasing importance, encoding the position of the non discarded coefficients using significance maps. Compar...

BACKGROUND In the concept of cloud-computing-based systems, various authorized users have secure access to patient records from a number of care delivery organizations from any location. This creates a growing need for remote visualization, advanced image processing, state-of-the-art image analysis, and computer aided diagnosis. OBJECTIVES This paper proposes a system of algorithms for automa...
