Reliable background suppression for complex scenes

open access: yesProceedings of the 4th ACM international workshop on Video surveillance and sensor networks, 2006
This paper describes a system for motion detection based on background suppression,specifically conceived for working in complex scenes with vacillating background,camouflage, illumination changing, etc.. The system contains proper techniques for background bootstrapping, shadow removal, ghost suppression and selective updating of the background model.

Factor analysis for background suppression

Object recognition supported by user interaction for service robots, 2003
Factor analysis (FA) is a statistical technique similar to principal component analysis (PCA) for explaining the variance in a data set in terms of underlying linear factors. Unlike PCA, however FA has not been widely exploited for face or object recognition.

Background suppressed magnetization transfer MRI

Magnetic Resonance in Medicine, 2019
PurposeUp to 30% of the hydrogen atoms in brain tissue are part of molecules (“semisolids”) other than water. In MRI, their magnetization is typically not observed directly, but can influence the water magnetization through magnetization transfer (MT).
