Clustering is a well-established technique for segmentation. However, clustering validation is rarely used for this purpose. In this work we adapt a clustering validation method, Clustering Stability (CS), to automatically ...

Cefazolin sodium (CFZ) is a semi-synthetic first-generation cephalosporin used for the treatment of infections caused by Gram-positive and Gram-negative microorganisms. Although it is a drug used worldwide, there are only ...

The success of handheld video capturing devices has further fueled the need of improved video stabilization. The videos often contain many foreground facial features like eyes, nose etc. These foreground features can be ...

We present a hardware architecture for real-time digital video stabilization for high-performance embedded systems. The stabilization algorithm analyzes the current and past video frames and obtains a motion estimation ...

Image acquisition systems based on multi-head arrangement of digital camerasare attractive alternatives enabling a larger imaging area when compared to a single framecamera. The calibration of this kind of system can be ...

Different surface roughnesses of six chocolate samples were produced by molding over sandpaper of different graininess. Surfaces were examined for roughness (laser scanning microscopy), color and image texture (digital ...

The use of ocular prostheses for ophthalmic patients aims to rebuild facial aesthetics and provide an artificial substitute to the visual organ. Natural intemperate conditions promote discoloration of artificial irides and ...
