Unsupervised novelty detection using Gabor filters for defect segmentation in textures.

30 Aug 2009 Gabor wavelets are applied to develop an unsupervised novelty method for defect detection and segmentation that is fully automatic and free of any adjustable parameter. The algorithm combines the Gabor analysis of the sample image with a statistical ... Read more...

Effective broadband refractive index retrieval by a white light optical particle counter.

Aug 2009 A new approach to retrieve the effective broadband refractive indices (nbroad,eff) of aerosol particles by a white light aerosol spectrometer (WELAS) optical particle counter (OPC) is presented. Using a tandem differential mobility analyzer ... Read more...

Single shot amplitude and phase characterization of optical arbitrary waveforms.

Aug 2009 Using a time-gated dual quadrature spectral interferometry technique, for the first time we demonstrate single-shot characterization of both spectral amplitude and phase of approximately 1THz bandwidth optical arbitrary waveforms generated from a 10 ... Read more...
