Image Quality Assessment Using Edge Correlation

In literature, oriented filters are used for low-level vision tasks. In this paper, we propose use of steerable Gaussian filter in image quality assessment. Human visual system is more sensitive to multidirectional edges present in natural images. The most degradation in image quality is caused due to its edges. In this work, an edge based metric termed as steerable Gaussian filtering (SGF) quality index is proposed as objective measure for image quality assessment. The performance of the proposed technique is evaluated over multiple databases. The experimental result shows that proposed method is more reliable and outperform the conventional image quality assessment method

Ethnobotanical notes on some potential wild edible fruits used by the Bhotia community of Niti Valley, Uttarakhand, India

135-144The present study deals with the diversity, distribution and ethnobotany of wild edible fruits consumed by the Bhotia tribe of Niti valley, Chamoli, Uttarakhand, India. Most of these valuable resources fulfil the nutritional, health and economic requirements of Bhotia community up to a large extent. Though the wild edible fruits have great socio-economic significance in sustenance of many tribal/rural communities but due to the increasing trends of modernized agriculture, climate change and various natural and anthropogenic hazards, a large number of genetic resources of wild edible fruits are under severe threat, hence warrants immediate attention for their conservation, domestication and utilization through improvement/selection. Keeping this in view, ethnobotanical knowledge and diversity distribution patterns of 27 potential wild edible fruits consumed by Bhotia tribe in Niti Valley have been recorded with their botanical names, family, local names, uses and indigenous processing methods

Comparative study on structural, electronic, optical and mechanical properties of normal and high pressure phases titanium dioxide using DFT

In this paper, a Self-consistent Orthogonalized linear combination of atomic orbitals (OLCAO) technique with a generalized gradient approximation such as Perdew–Burke–Ernzerhof Solid (GGA-PBE SOL) has been used to scrutinize the structural, optical, electronic and mechanical properties of normal pressure phase (Anatase and Rutile) and high pressure phase i.e., cubic (Fluorite and Pyrite) TiO _2 . Electronic and optical properties of normal pressure phases of TiO _2 are also investigated using (Meta) MGGA-Tran and Blaha (TB09) and obtained results are a close approximation of experimental data. It is seen that the virtually synthesized structural parameter for cubic and tetragonal phases of TiO _2 are consistent with experimental and theoretical data. From the effective mass of charge carriers (m*), it can be observed that pyrite TiO _2 is having lower effective mass than the fluorite and hence shows higher photocatalytic activity than fluorite. Furthermore, it is seen that fluorite is more dense than anatase, rutile and pyrite TiO _2 . From the theoretical calculations on the optical properties, it can be concluded that optical absorption occursin the near UV region for high and normal pressue phases of TiO _2 . Again from the reflectivity characteristics R( ω ), it can be concluded that TiO _2 can be used as a coating material. Elastic constants, elastic compliance constants, mechanical properties are obtained for anatase, rutile, fluorite and pyrite TiO _2 . A comparison of the results with previously reported theoretical and experimental data shows that the calculated properties are in better agreement with the previously reported experimental and theoretical results
