Recent Developments in Morphological Algorithms
In the implementation of morphological image analysis transformations, several algorithmic techniques can be considered. The well-known parallel and sequential algorithms generally involve a large number of scannings of all the pixels and are thus ine cient on classical computers. To overcome this drawback, there have been proposed two main families of algorithms, whose common characteristic is...
متن کاملRecent Advances in Morphological Cell Image Analysis
This paper summarizes the recent advances in image processing methods for morphological cell analysis. The topic of morphological analysis has received much attention with the increasing demands in both bioinformatics and biomedical applications. Among many factors that affect the diagnosis of a disease, morphological cell analysis and statistics have made great contributions to results and eff...
متن کاملClimate, Tectonics or...?: Speculations on the Recent Paleolimnology of Yellowstone Lake
The sediments of Yellowstone Lake may reveal the paleoecological history of this lake over the last few centuries. These sediments contain up to 60% biogenic silica derived from diatom frustules settling out from the overlying water. The sediment record reveals large variations in the diatom deposition over the last ~350 years. Some of these variations appear to correlate extremely well with in...
متن کاملSpeculations on Story Puns
There is a class of joke which consists of an anecdote , which is sometimes quite long and often has no inherently humorous content, followed by a punchline which is a distorted form of some well-known phrase, proverb or quotation. Usually the punchline purports to summarise or draw a moral from the preceding story. This genre has some unusual aspects, from the viewpoint of conventional claims ...
متن کاملSpeculations on Hodge theory
Recall that a Mumford–Tate domain DM is an open set in its compact dual ĎM — the latter is a rational homogeneous variety defined over Q (think of the upper half plane H ⊂ P1). Thus a polarized Hodge structure (PHS) φ has an “upstairs” field of definition k(φ). If H•,• ⊂ T •,• is a subalgebra then the Noether-Lefschetz locus NLH = {φ : Hg•,• φ ⊇ H} is defined over Q. Its components are defined ...
