New grayscale hit-miss operator

Ship detection in satellite imagery using rank-order grayscale hit-or-miss transforms

Ship detection from satellite imagery is something that has great utility in various communities. Knowing where ships are and their types provides useful intelligence information. However, detecting and recognizing ships is a difficult problem. Existing techniques suffer from too many false-alarms. We describe approaches we have taken in trying to build ship detection algorithms that have reduc...

The TARGET trial: hit or miss?

Over the past 8 years large-scale, placebo-controlled trials have established the efficacy of intravenous platelet glycoprotein (GP) IIb/IIIa inhibitors at reducing the 30-day composite of death, myocardial infarction, and urgent target vessel revascularization associated with percutaneous coronary angioplasty, atherectomy, and stent placement. Using abciximab, tirofiban, or eptifibatide, each ...

When does a hit = a miss?

The Simultaneous Proxy Evaluation (SPE) architecture allows one to evaluate implemented proxies in a live network environment and be able to make performance comparisons between black-box systems. When using a real workload on a live network with real content, SPE is additionally able to evaluate prefetching proxies. The SPE architecture requires, as a component, a proxy cache that serves all c...

Estimating Cache Hit Rates from the Miss Sequence

This paper considers the problem of inferring cache hit rates from observations of references that miss in the cache. In the Web context, this is the problem of inferring a browser's cache hit rate by examining the requests that it issues to origin servers. We show that a case of this problem can be solved.
