The aim of feature extraction is to create a new set of features (mathcal {F'}) based on the original feature set ({mathcal {F}}). Because feature extraction is applied on the training dataset, it has to produce a mapping function capable of transforming any future examples (pmb {x}) to the same feature space. This is due to the fact ...

Boundary extraction of images is approached by two main methods: polygonal and digital. Polygonal (or bevelled-form) methods represent the boundary as a set of edges (2D) or triangles (3D) [1] . Digital (or block-form) methods represent the boundary as a set of axis-aligned edges (2D) or faces (3D) that can be voxel size [2] or maximal, …

Due to its biocompatibility, biodegradability, and film-forming properties, as well as high stability, ulvan has shown promising potential as an ingredient of biopolymer films such as sustainable and readily biodegradable …
Extraction means drawing a compound out of a mixture using a solvent. Solvent partitioning is more specific. It means compounds have a "choice" of two solvents that they can dissolve in. Some compounds dissolve in one solvent. Some compounds dissolve in the other solvent. That way the compounds in the mixture become separated into two groups.
