Extraction of parametrically defined geometric primitives ...

Extraction is a generalization of fitting, and is sometimes given the name robust fitting. In ordinary fitting the assumption is made that all the points belong to the curve or surface being fit. In extraction, or robust fitting, this assumption does not hold. Thus an extraction routine must return not only the equation of the best primitive (curve or surface), but also which of the data ...

Extract data in volVectorField to a primitive C or C++ ...

 · I would recommend you to take a look at OpenFOAM''s container classes as they build the underlying data structure for the fields (e.g. volVectorField or volScalarField).Specifically have a look at the List [1] and UList [2] classes. Now, assuming f is of type volScalarField, you would get access to the internal field (i.e. without the boundaries) like this:

CARNEGIE-MELLON UNIVERSITY IMPROVED PRIMITIVE …

Abstract. A system developed for arrhythmia analysis of Holter ECGs employs a syntactic pattern recognition approach. This system consists of two independent stages: 1) primitive extraction- digitized ECG data is reduced to sequence of predefined subpattern shapes or "primitives", and 2) syntactical analysis- the primitive sequence is analyzed in accordance with syntactic principles ...

1. Load a Primitive. The first step in order to run a primitive is to load it. This will be done using the mlprimitives.load_primitive function, which will load the indicated primitive as an MLBlock Object from MLBlocks. In this case, we will load the mlprimitives.custom.feature_extraction.CategoricalEncoder primitive.

Faster primitive data extraction
