Light interreflections occurring in a concave object generate a color gradient which is characteristic of the object’s spectral reflectance. In this paper, we use this property in order to estimate the spectral reflectance of matte, uniformly colored, V-shaped surfaces from a single RGB image taken under directional lighting. First, simulations show that using one image of the concave object is...

To create appealing realistic visual effects, complete geometric models, lightings, and material properties of a scene are often required in film production or augmented reality. This compact representation also enables various applications in many image synthesis and editing tasks. In this paper, we introduce an iterative photometric stereo approach via non-negative matrix factorization (NMF) ...

This study aims to analyze the quality of lightings in the indoor badminton courts in Taichung, Taiwan. The study was conducted on-site and illuminance values were analyzed. A digital illuminance meter and handheld distance meter were used as the main measuring tools. Data was collected and analyzed by SPSS for 11.0. The results show that Guoguang Badminton Court has reached the “leisure” grade...

Abstracts Quantum dot light-emitting diodes (QD-LEDs) are considered as competitive candidate for next-generation displays or lightings. Recent advances in the synthesis of core/shell quantum dots (QDs) and tailoring procedures achieving their high yield have facilitated emergence high-performance QD-LEDs. Meanwhile, charge-carrier dynamics QD-LED devices, which constitutes remaining core resea...

Abstract Accident occurring at junctions is a major problem in India. As per the annual report 2019, almost 50% of road accidents India occurred junctions. In this study, an attempt has been made to study safety aspects minor on MDR 132 Palwal District Haryana State. The main aims present are MDR-132 from Nuh Hodal by analyzing various features like markings, signs, shoulders, sight distances, ...

Household garbage images are usually faced with complex backgrounds, variable illuminations, diverse angles, and changeable shapes, which bring a great difficulty in image classification. Due to the ability discover problem-specific features, deep learning especially convolutional neural networks (CNNs) have been successfully widely used for representation learning. However, available stable ho...
