3-D WAVELET CODEC (COMPRESSION/DECOMPRESSION) FOR 3-D MEDICAL IMAGES PLChithra and A.Christoper TamilMathi
Compression is an important part in image processing in order to save memory space and reduce the bandwidth while transmitting. The main purpose of this paper is to analyse the performance of 3-D wavelet encoders using 3-D medical images. Four wavelet transforms, namely, Daubechies 4,Daubechies 6,Cohen-Daubechies-Feauveau 9/7 and Cohen Daubechies-Feauveau5/3 are used in the first stage with enc...
متن کاملProbabilistic Registration of 3-D Medical Images
Registration between 3-D images of human anatomies enables cross-subject diagnosis. However, innate differences in the appearance and location of anatomical structures between individuals make accurate registration difficult. We characterize such anatomical variations to achieve accurate registration. We represent anatomical variations in the form of statistical models, and embed these statisti...
متن کاملImmediate ROI Search for 3-D Medical Images
The objective of this work is a scalable, real-time, visual search engine for 3-D medical images, where a user is able to select a query Region Of Interest (ROI) and automatically detect the corresponding regions within all returned images. We make three contributions: (i) we show that with appropriate off-line processing, images can be retrieved and ROIs registered in real time; (ii) we propos...
متن کاملWavelet - Based 3 D Compression
Interactive visualization of very large volume data has been recognized as a task requiring great eeort in a variety of science and engineering elds. In particular, such data usually places considerable demands on run-time memory space. In this paper, we present an eeective 3D compression scheme for interactive visualization of very large volume data, that exploits the power of wavelet theory. ...

A (‘oni1non assumpt,ion of the shape from texture problc~ri s that i i perceived imago mainly contains only one type of texture with the sanic’ surface orientation. Unfortuiiatelly. a natural image is often composed of more than onc: t,exures. In order t,o solve the shape from tcxturc problern in a practical manner, we need to segment, 3D textured images. In this paper, we propose a new algorit...
