Illumination-invariant image processing is an extension of the classical technique of homomorphic filtering using a logarithmic point transformation. In this paper, traditional approaches to illumination-invariant processing are briefly reviewed and then extended using newer image processing techniques. Relevant hardware considerations are also discussed including the number of bits per pixel r...

Certain nematicidal treatments for the control of root knot of tobacco in six field experiments in North Carolina were used to determine early, midseason, and postharvest densities of eggs and larvae of Meloidogyne spp., postharvest root-knot indices, and crop yield and value. Various statistical correlations showed that population densities determined 6-8 wk after transplanting were more indic...

In this study, we use the cell dynamics method to test the validity of the Kormogorov-JohnsonMehl-Avrami (KJMA) theory of phase transformation. This cell dynamics method is similar to the well-known phase-field model, but it is a more simple and efficient numerical method for studying various scenarios of phase transformation in a unified manner. We find that the cell dynamics method reproduces...

The main aim of this research paper is to introduce a new extension the Gauss hypergeometric function and confluent by using an extended beta function. Some functional relations, summation integral representations, linear transformation formulas, derivative formulas for these functions are derived. We also logarithmic convexity some important inequalities

First time a theoretical prediction of the neutron electromagnetic form factors behaviors in whole region their definition by use proton data only is demonstrated. This could be achieved framework unitary and analytic approach to description nucleon with canonical normalization conditions, QCD (up logarithmic correction) asymptotic specific transformation properties current isotopic space.

In traditional warped FIR and IIR filters, the frequency-warping profile is adjusted by a single free parameter, leading to a less flexible allocation of frequency resolution. As an example, it is not possible to achieve a truly logarithmic frequency resolution, which would be often desired in audio applications. In this paper a new approach is presented for warped IIR filter design where the f...

Motivated by Wakimoto free field realisations, the bosonic ghost system of central charge c= 2 is studied using a recently proposed formalism for logarithmic conformal field theories. This formalism addresses the modular properties of the theory with the aim being to determine the (Grothendieck) fusion coefficients from a variant of the Verlinde formula. The key insight, in the case of bosonic ...

The authors investigated the pigeon's ability to generalize object discrimination performance to smaller and larger versions of trained objects. In Experiment 1, they taught pigeons with line drawings of multipart objects and later tested the birds with both larger and smaller drawings. The pigeons exhibited significant generalization to new sizes, although they did show systematic performance ...

Decomposition of multi-exponential and related signals is generalized as a filtering problem on a logarithmic time or frequency scale and FIR filters operating with logarithmically sampled data are proposed to use for its implementation. The filter algorithms and types are found for various time-domain and frequencydomain mono-components. It is demonstrated that the ill-posedness in the multi-c...
