Spectral Sharpening of Color Sensors: Diagonal Color Constancy and Beyond
Sensors, 2014 It has now been 20 years since the seminal work by Finlayson et al. on the use of spectral sharpening of sensors to achieve diagonal color constancy. Spectral sharpening is still used today by numerous researchers for different goals unrelated to the ...

A sharpening of the Parikh mapping [PDF]
RAIRO - Theoretical Informatics and Applications, 2001 Summary: We introduce a sharpening of the Parikh mapping and investigate its basic properties. The new mapping is based on square matrices of a certain form. The classical Parikh vector appears in such a matrix as the second diagonal. However, the matrix product gives more information about a word than the Parikh vector.

Automation of Pan-Sharpening Methods for Pléiades Images Using GIS Basic Functions
Remote Sensing, 2021 Pan-sharpening methods allow the transfer of higher resolution panchromatic images to multispectral ones concerning the same scene. Different approaches are available in the literature, and only a part of these approaches is included in remote sensing ...

Sharpening of graded diamond grinding wheels
SN Applied Sciences, 2023 Grinding the flutes of cemented carbide end mill cutters results in high and uneven radial wear of the grinding wheel. This is a consequence of the varying geometrical contact conditions over the grinding wheel width.

The influence of different cutting parameters on the glass edge quality [PDF]
E3S Web of Conferences, 2020 The influence of different cutting parameters on the glass edge quality was investigated, including the cutter material, the sharpening angle of the cutting roll, the cutting speed and the load applied to the roll.

Optimal Sharpening of Compensated Comb Decimation Filters: Analysis and Design
The Scientific World Journal, 2014 Comb filters are a class of low-complexity filters especially useful for multistage decimation processes. However, the magnitude response of comb filters presents a droop in the passband region and low stopband attenuation, which is undesirable in many ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
