That is how spam filters are created in the round-the-clock war room run by Brightmail, a company that performs filtering for Internet service providers like Earthlink, MSN and AT&T Worldnet as well as companies trying to keep their e-mail systems unclogged.
Note that some alternative statistics could be used instead of median in step 4. Minor differences in the algorithm setup (size of neighborhood, filter in step 4, number k of uncorrupted pixels in the neighborhood to perform filtering, strategy for handling unprocessed pixels, etc).
With this grouping of samples we can perform filtering analyses for many different purposes, as illustrated by the examples in Figure 3B E.
While this type of filtering works well for many algorithms, it is much more efficient to perform filtering locally on a surface for algorithms such as texture mapping.
The best performing filters for NNR were SIGN, BMJ Clinical Evidence filter, and the health-evidence.ca SR search filter at 118, 167.9, and 186 respectfully.
Our best performing filters for PubMed, Ovid Medline, and Embase are shown in Table 2, categorized by high-sensitivity and high-specificity.
To perform GWAS, filtering for low MAF (10% threshold) and missing data (10%), 5,795 SNPs were performed.
BorderWare Dynamic Inspection is a real-time engine performing content filtering for every webpage along with URL categorization and anti-malware.
Following a different approach, the work in [12] proposed a system that performs particle filtering for detection of sleeping cells.
Based on the 2D spectrum expression of the SAR echo signal shown in (15) and (16), first the phase of the echo signal is coarsely compensated by performing match filtering for the center point and then the residual range-variant phase is compensated in range Doppler domain.
