Exemplar-Based Sketch Colorization with Cross-Domain Dense Semantic Correspondence

open access: yesMathematics, 2022
This paper aims to solve the task of coloring a sketch image given a ready-colored exemplar image. Conventional exemplar-based colorization methods tend to transfer styles from reference images to grayscale images by employing image analogy techniques or

Four-coloring model and frustrated superfluidity in the diamond lattice

open access: yes, 2013
We propose a novel four-coloring model which describes "frustrated superfluidity" of $p$-band bosons in the diamond optical lattice. The superfluid phases of the condensate wavefunctions on the diamond-lattice bonds are mapped to four distinct colors at ...

Preparation of Duplex Film through Microarc Oxidation Coloring and Polymer Plating on Mg-Li Alloy and Its Corrosion Resistance

open access: yesInternational Journal of Electrochemical Science, 2013
Microarc oxidation (MAO) coloring and developed polymer plating technique were applied to Mg-Li alloy to get greenish super-hydrophobic film. The formation mechanism, wettability and corrosion resistance of the film were characterized by X-ray ...

On dispersion curve coloring for mechanical metafilters

open access: yesScientific Reports, 2022
AbstractThis paper formalizes smooth curve coloring (i.e., curve identification) in the presence of curve intersections as an optimization problem, and investigates theoretically properties of its optimal solution. Moreover, it presents a novel automatic technique for solving such a problem.

Approximations of the aggregated interference statistics for outage analysis in massive MTC [PDF]

open access: yes, 2019
This paper presents several analytic closed-form approximations of the aggregated interference statistics within the framework of uplink massive machine-type-communications (mMTC), taking into account the random activity of the sensors.

Transcriptome and Metabolome Profiling Provide Insights into Flavonoid Biosynthesis and the Mechanism of Color Formation in Zanthoxylum bungeanum Maxim.

open access: yesPlants
The color of Zanthoxylum bungeanum Maxim. (Z. bungeanum) is a key quality indicator and a factor limiting the development of its industry. However, the underlying mechanisms governing color formation remain largely unexplored.

Spectrum Sharing for LTE-A Network in TV White Space

open access: yes, 2017
Rural areas in the developing countries are predominantly devoid of Internet access as it is not viable for operators to provide broadband service in these areas. To solve this problem, we propose a middle mile Long erm Evolution Advanced (LTE-A) network

A Correlation Between Inclination and Color in the Classical Kuiper Belt [PDF]

open access: yes, 2002
We have measured broadband optical BVR photometry of 24 Classical and Scattered Kuiper belt objects (KBOs), approximately doubling the published sample of colors for these classes of objects. We find a statistically significant correlation between object
