Abstract:
... Na⁺₂Eu³⁺₂:Ca₆(PO₄)₆F₂ is explored as a potential host for radioactive waste immobilization. Since Eu³⁺ ion is a surrogate of highly radioactive Am³⁺ ion, the photoluminescence (PL) characteristics of Eu³⁺ ion helped to investigate the possible distribution of hazardous and radioactive Am³⁺ ion among the two lattice sites in the matrix. It was observed that Am³⁺ will prefer to occupy the Ca2-site l ...

Abstract:
... Diketopyrrolopyrrole (DPP) pigments are essential and have been intensively exploited as building-blocks for the synthesis of organic semiconducting polymers and small molecules; however, DPP derivatives as emissive materials for electroluminescent (EL) devices have rarely been explored. In this work, a series of new DPP derivatives grafted with carbazole dendrons in a non-conjugated fashion using ...

Abstract:
... Superpixels group perceptually similar pixels into homogeneous sub-regions that act as meaningful features for advanced tasks. However, there is still a contradiction between color homogeneity and shape regularity in existing algorithms, which hinders their performance in further processing. In this work, a novel Contour Optimized Non-Iterative Clustering (CONIC) method is presented. It incorporat ...

Abstract:
... Consumers tend to associate stimuli across different senses, such as the color and flavor of foods or drinks. After repeated exposure to the packaging of mainstream food products, consumers can even associate a certain packaging color and a given flavor label. Previous research has demonstrated the influence of these packaging color-flavor label associations on the visual search for a certain flav ...

Many fruit recognition works have applied statistical approaches to make an exact correlation between low-level visual feature information and high-level semantic concepts given by predefined text caption or keywords. Two common fruit recognition models include bag-of-features (BoF) and convolutional neural network (ConvNet), which achieve high-performance results. In most cases, the overfitting p ...

Abstract:
... One of the first steps in evaluating fisheries acoustic data is to explore an echogram of the data. Echograms are a visual representation of reflected sound with range or distance from the echosounder on the y-axis, time on the x-axis, and the intensity of the reflected sound displayed through a mapped color scale. Many of the traditional color scales used in fisheries acoustic echograms have not ...

Abstract:
... Accurate and nondestructive maturity discrimination of tomatoes is significant for harvest and preservation. Color differences between intermediate adjacent maturity stages are not significant, so it is time-consuming to obtain a large amount of precise maturity labels and difficult to discriminate multiple maturity stages by visual features merely. This study designed a semi-supervised method bas ...
