To detect interest points, SURF uses an integer approximation of the determinant of Hessian blob detector, which can be computed with 3 integer operations using a precomputed integral image. Its feature descriptor is based on the sum of the Haar wavelet response around the point of interest. These can also be computed with the aid of the ...
Cover of the comic book "THE SHMOO" The plot takes its name from the Shmoo, a fictional species created by Al Capp in the cartoon Li'l Abner.These small, blob-like creatures have shapes similar to the "working" volumes that would be enclosed by shmoo plots drawn against three independent variables (such as voltage, temperature, and response speed).
For example, by proceeding beyond the first delimiting saddle point a "grey-level blob tree" can be constructed. Moreover, the grey-level blob detection method was embedded in a scale space representation and performed at all levels of scale, resulting in a representation called the scale-space primal sketch.
A spur or track in radiation chemistry is a region of high concentration of chemical products after ionizing radiation passes through. The spur model, proposed by Samuel and Magee in 1953, describes the kinetic behavior of reaction spurs involving one type of radicals in a diffusion-driven environment. [1]
Physarum polycephalum, an acellular [1] slime mold or myxomycete popularly known as "the blob", [2] is a protist with diverse cellular forms and broad geographic distribution. The “acellular” moniker derives from the plasmodial stage of the life cycle : the plasmodium is a bright yellow macroscopic multinucleate coenocyte shaped in a ...
The simplest form of a group-contribution method is the determination of a component property by summing up the group contributions : [] = +.This simple form assumes that the property (normal boiling point in the example) is strictly linearly dependent on the number of groups, and additionally no interaction between groups and molecules are assumed.
Blobs are sections of primary visual cortex (V1) above and below layer IV where groups of neurons sensitive to color assemble in cylindrical shapes. They were first identified in 1979 by Margaret Wong-Riley in cats when she used a cytochrome oxidase stain, from which they get their name. [ 1 ]
Coupled-cluster theory can also be used to obtain solutions for excited states using, for example, linear-response, [7] equation-of-motion, [8] state-universal multi-reference, [9] or valence-universal multi-reference coupled cluster [10] approaches. The wavefunction of the coupled-cluster theory is written as an exponential ansatz:
