Fault-tolerant and progressive transmission of images
Pattern Recognition, 2005A fault-tolerant progressive image transmission method is proposed. The advantages include the following: (1) Unlike most progressive methods, the image is divided into n parts with equal importance to avoid worrying about which part is lost or transmitted first. (2) If the image is a secret image, then the transmission can use n distinct channels (one

Progressive vector transmission
Proceedings of the 7th ACM international symposium on Advances in geographic information systems, 1999Progressive transmission of raster images over the WorldWide Web has been successfully applied to provide the user with coarser versions of the data before downloading a complete image. On the other hand, in the vector domain progressive transmission is challenging.

Progressive image transmission
IEEE Transactions on Circuits and Systems for Video Technology, 1993Progressive image transmission (PIT) is widely used in many applications, since it generates the successively improved reconstructions of an image. In spatial domain PIT systems, perfectly reconstructed images can be obtained at the final stage. However the intermediate images are not good and there is no data compression.

Progress of Transmission Technologies for UDTV
Proceedings of the IEEE, 2013This paper describes the recent progress of research and development on transmission technologies for Super Hi-Vision (SHV), which is the form of ultrahigh-definition television (UHDTV) with the highest resolution class. The paper covers the transmission systems for SHV program production and satellite broadcasting.

Making Progressive Transmission Adaptive
IEEE Transactions on Communications, 1986Progressive transmission hierarchically reorganizes the information in an image with the aim of increasing transmission efficiency on a low bandwidth channel. We have developed methods for adaptively choosing initial and successive approximations to be sent when the end user is a human telebrowsing through a database to find particular desired images ...

The progressive transmission disadvantage
IEEE Transactions on Information Theory, 1997Summary: The disadvantage of progressive transmission, compared to transmission in a single step, is analyzed for the high-rate case using a polytope that is self-similar under binary subdivision. This disadvantage is calculated to be 0.3424 dB or 0.057 bit compared to scalar quantization, obtained with a step size of 1 bit per ensemble.

Progress in Modelling Malaria Transmission
2010Transmission of human malaria is a complicated dynamic process that involves populations of humans, parasites, and vectors. The first mathematical models of malaria are now more than a century old, and they are still a useful conceptual synthetic description of transmission, but they fail in some important ways.

Vertical Transmission of Progressive Pneumonia of Sheep
American Journal of Veterinary Research, 1975SUMMARY Forty-two lambs were derived by hysterectomy from 27 ewes. Eight ewes had lesions of chronic progressive pneumonia (cpp) and 19 did not. Eleven lambs were derived from ewes with lesions of cpp. These 11 lambs were maintained in isolators under germfree conditions until killed at 2 to 4 months of age. Lungs from each lamb were examined for gross

Progressive compression and transmission of PointTexture images
Journal of Visual Communication and Image Representation, 2006Abstract A progressive compression and transmission algorithm for PointTexture 3-D images is proposed in this work. The proposed algorithm represents a PointTexture image hierarchically using an octree. The geometry information in octree nodes is encoded by the predictive partial matching (PPM) method, while the color information is encoded using the

Recent progress in soliton transmission technology
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2000Recent progress on time-division multiplexed (TDM) and wavelength-division multiplexed (WDM) soliton transmission is described, in which dispersion management plays an important role in increasing the power margin and the dispersion tolerance. The characteristics of the dispersion-managed soliton are compared with those of return to zero and nonreturn ...
