Segmentation of 3-D Textured Images Using Continuous Wavelet Transform
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...
متن کامل3-D Reconstruction of Medical Image Using Wavelet Transform and Snake Model
Medical image segmentation is an important step in 3-D reconstruction, and 3-D reconstruction from medical images is an important application of computer graphics and biomedicine image processing. An improved image segmentation method which is suitable for 3-D reconstruction is presented in this paper. A 3-D reconstruction algorithm is used to reconstruct the 3-D model from medical images. Roug...
متن کامل3-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 کاملOverview of 3-D Reconstruction from Images
This article summarizes recent advancements of the theories and techniques for 3-D reconstruction from multiple images. We start with the description of the camera imaging geometry as perspective projection in terms of homogeneous coordinates and the definition of the intrinsic and extrinsic parameters of the camera. Next, we described the epipolar geometry for two, three, and four cameras, int...
متن کاملGuest Editorial Fully 3-D Reconstruction of Medical Images
T ODAY, the majority of biomedical tomography systems on the market (e.g., modern positron emission tomog-raphy (PET), single photon emission computed tomography (SPECT), and X-ray cone-beam computed tomography (CT) devices) acquire projection data in 3-D mode. The detectors these devices employ have an axial extent which seems to increase steadily with the introduction of new systems. This all...
