Journal ArticleDOI
Euclidean distance mapping
TL;DR: It is shown that skeletons can be produced by simple procedures and since these are based on Euclidean distances it is assumed that they are superior to skeletons based on d4−, d8−, and even octagonal metrics.
Journal ArticleDOI
Three-dimensional microscopy using a confocal laser scanning microscope.
TL;DR: In a scanning laser microscope detecting fluorescent light from the specimen, the depth-discriminating property of confocal scanning has been used to carry out optical slicing of a thick specimen.
Journal ArticleDOI
Regularized iterative weighted filtered backprojection for helical cone-beam CT
TL;DR: Results show that for cone angles up to +/-2.78 degrees, cone artifacts are suppressed and windmill artifacts are alleviated within three iterations, and the authors believe that iterative improvement with non-exact methods is a promising technique for medical CT applications.
Journal ArticleDOI
High-accuracy rotation of images
TL;DR: Bilinear interpolation has been employed as well as bicubic functions of size 2 × 2, 4 × 4 and 8 × 8 as an indicator of the quality of the rotation algorithm and the interpolation technique.
