Pandora: Description of a Painting Database for Art Movement Recognition with Baselines and Perspectives

To facilitate computer analysis of visual art, in the form of paintings, we introduce Pandora (Paintings Dataset for Recognizing the Art movement) database, a collection of digitized paintings labelled with respect to the artistic movement. Noting that the set of databases available as benchmarks for evaluation is highly reduced and most existing ones are limited in variability and number of images, we propose a novel large scale dataset of digital paintings. The database consists of more than 7700 images from 12 art movements. Each genre is illustrated by a number of images varying from 250 to nearly 1000. We investigate how local and global features and classification systems are able to recognize the art movement. Our experimental results suggest that accurate recognition is achievable by a combination of various categories.To facilitate computer analysis of visual art, in the form of paintings, we introduce Pandora (Paintings Dataset for Recognizing the Art movement) database, a collection of digitized paintings labelled with respect to the artistic movement.

Influence of the electrochemical treatment on the magnetic properties of nanowires

Abstract: Synthesis of nanomaterials is one of the most researched areas. Nanomaterials are at the core of all modern nano-devices. The reduced size helps electronics to have increased performance, low energy consumption and low heat output. Properties of nanomaterials are mainly related to the involved large surface to volume ratio. Nanomaterials can be fabricated using different methods. One of the intensely used, inexpensive and with high degree of reproducibility is electrochemistry (EC), which can be used either to destroy (corrosion) or to create (thin films, nanoparticles, nanowires (NWs), etc.) materials. In this paper we focus on the effect of the electrochemical treatment (EchT) on the structural and magnetic properties of nanowires. Ni NWs were synthesized and analyzed by SQUID to study the magnetic properties induced by the EchT of the Au substrate. Ni NWs were synthesized in a gold-coated PCTE membrane using template synthesis. The EchT induced structural modifications of the Au substrate and further modifications of NWs magnetism.
