Automated Mapping of Water Bodies from Resourcesat-2 Awifs Image Using Automated Algorithm, Nalgonda District, Telangana State, India.

Automated Image-Based Mapping

We describe an approach to the automated construction of visual maps of an unknown environment. These maps take the form of image-based “walk-throughs” rather than 2D or 3D models. Our approach is based on the selection of informative viewpoints within the environment. These viewpoints are locations in the environment associated with views containing maximal visual interest. This approach to en...

Antibacterial Activity of Certain Members of Chlorophyceae From Warangal District, Telangana State, India

Chloroform and Methanol extracts of three genera of algae (Oedogonium crispum (Hassal) Wittrock, Rhizoclonium hieroglyphicum (Ag)Kuetz. and Spirogyra biformis C-C.Jao.) from fresh water of Warangal District were tested in vitro for their antibacterial activities against two strains of gram positive bacteria (Bacillus cereus and Staphylococcus aureus) and two strains of gram negative bacteria (K...

Novel Automated Method for Minirhizotron Image Analysis: Root Detection using Curvelet Transform

In this article a new method is introduced for distinguishing roots and background based on their digital curvelet transform in minirhizotron images. In the proposed method, the nonlinear mapping is applied on sub-band curvelet components followed by boundary detection using energy optimization concept. The curvelet transform has the excellent capability in detecting roots with different orient...

Drinking water pollution with respective of fluoride in the semi-arid region of Basara, Nirmal district, Telangana State, India

Fluoride is an essential microelement for human health. Statistically, smaller quantities (<1.0 mg/L) in drinking water are usually considered to have a beneficial effect on the rate of occurrence of dental caries, particularly among children, but excessive continuous exposure (>1.5 mg/L) to fluoride can give rise to a number of adverse effects, including dental fluorosis, skeletal fluorosis, i...
