Requires signed TDF.; In digital image processing, texture has always been considered a vital element for both modelling and analysis of images. One method of analysing texture is to examine it at a number of different resolutions. The thesis focuses on issues arising from this multi-resolution ...

In particular, noise correlation matrix N may be estimated from ypre signal and signal correlation matrix R may be estimated from ypst signal. The ypst signal is also used for evaluation of the fidelity of reconstruction, as a filter Wf produces an estimate of the activity signal source \(...
We present a new patch-based image restoration algorithm using an adaptive Wiener filter (AWF) with a novel spatial-domain multi-patch correlation model. The new filter structure is referred to as a collaborative adaptive Wiener filter (CAWF). The CAWF e
(PNS) followed by Endo- or Lyso-IP, which are either used directly for TOMAHAQ proteomics via a multi-step workflow or solubilized in 8 M urea/0.5% NP-40 and LMW filtration using a 50 kDa filter to purify Aβ peptides for TOMAHAQ proteomics.cThe indicated 293ELcells in ...
All leaves were imaged using a PlanNeoFluar Z 1×/0.25 dry objective and a Hamamatsu ORCA-Flash4.0 digital CMOS camera (c11440-22C) with 2 × 2 binning. mCherry-tagged Pst DC3000 was detected using the Zeiss filter set 45 (00000-1114-462), which includes a 560/40 nm excitation...
the EA-based and ANN-based methods can obtain better performances in the corresponding tasks. In unsupervised applications (including filter-based hyperspectral band selection, clustering, and unsupervised change detection), the performance is often affected by the optimization capability, due to the fact...
Radar Sea Clutter Suppression and Target Indication with a Spatial Tracking Filter It is an important issue to study sea clutter suppression because it could interfere with the detection of targets above the sea surface severely. Spatial ... J Liu,H Meng,H Zhang,... - 清华大学学报(英文版) ...
