The trilateral filter for high contrast images and meshes

ACM SIGGRAPH 2005 Courses on - SIGGRAPH '05, 2005
We present a new, single-pass nonlinear filter for edge-preserving smoothing and visual detail removal for N dimensional signals in computer graphics, image processing and computer vision applications. Built from two modified forms of Tomasi and Manduchi's bilateral filter, the new "trilateral" filter smoothes signals towards a sharply-bounded ...

High frequency contrast imaging

IEEE Ultrasonics Symposium, 2004, 2005
Ultrasound contrast agents enhance echoes from the microvasculature and enable the visualization of flow in smaller vessels. We optically and acoustically investigate the dynamics of a microbubble with 10 MHz ultrasound insonation. Results of a numerical evaluation of the modified Rayleigh-Plesset equation are used to predict the dynamics of a ...

MR image contrast at high field strength

Journal of Magnetic Resonance Imaging, 1991
AbstractThe T1 of soft tissues increases with magnetic field strength. Some tissue contrast may be diminished on high‐field‐strength magnetic resonance (MR) images when conventional TRs are used, because of altered T1 effects on the MR signals. This necessitates longer TRs in techniques that use long TRs, which prolongs the examination excessively ...

Reconstruction of high contrast images for dynamic scenes

The Visual Computer, 2011
High Dynamic Range (HDR) imaging requires one to composite multiple, differently exposed images of a scene in the irradiance domain and perform tone mapping of the generated HDR image for displaying on Low Dynamic Range (LDR) devices. In the case of dynamic scenes, standard techniques may introduce artifacts called ghosts if the scene changes are not ...
