Chemie Ingenieur Technik, EarlyView.A nonlinear kinetic model was developed and successfully implemented, which describes the degradation of the protein C‐phycocyanin depending on temperature and pH value. C‐phycocyanin had been extracted from two different cyanobacteria. In addition to protein degradation, the fading of the typical blue color of this protein was included in the model ...

Natural Enhancement of Color Image
EURASIP Journal on Image and Video Processing, 2010 A new algorithm of Natural Enhancement of Color Image (NECI) is proposed. It is inspired by multiscale Retinex model. There are four steps to realize this enhancement. At first, the image appearance is rendered by content-dependent global mapping for light cast correction, and then a modified Retinex filter is applied to enhance the local contrast ...

Colornet - Estimating Colorfulness in Natural Images [PDF]
2019 IEEE International Conference on Image Processing (ICIP), 2019 Measuring the colorfulness of a natural or virtual scene is critical for many applications in image processing field ranging from capturing to display. In this paper, we propose the first deep learning-based colorfulness estimation metric. For this purpose, we develop a color rating model which simultaneously learns to extracts the pertinent ...

EcoEnergy, EarlyView.This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.
