A great deal of features detectors and descriptors are proposed nowadays for various computer vision applications. The task of image processing which is invariant to all weather conditions (such as rain, fog, smoke, unfavorable lights, camera rotation) is... see more

?ontext. Increasing of productivity and extension of the functionality of modern computer vision systems require more effective methods for visual information processing. Main goals of structural recognition are related with the improvement of information... see more

Background. QSAR analysis is an important tool for the identification of pharmacophore fragments in biologically active substances and helps optimize the search for new effective drugs.Objective. The aim of the study was to determine the molecular descrip... see more

In this work, the density functional theory (DFT) method at the B3LYP/6-31 + G (d, p) level has used to determine the optimization of five rhodanine derivatives. The stability of the derivatives (7a-7e) of 5-arylidene rhodanine, the hyperconjugative inter... see more

Recently, substituted 1,8-dioxodecahydroacridine derivatives have been investigated and found to possess a wide variety of biological and phar­macological activities. Two of these biologically relevant N-heterocyclic scaf­folds, 2-(9-(4-me­th­oxyphenyl)-3... see more

This work deals with a Quantitative Structure-Activity study against Plasmodium falciparum of a series of Azetidine-2-carbonitrile derivatives. Using the MLR and MNLR methods from excel and xlstat software, we have been able to develop two QSAR models bas... see more

Through the B3LYP/6-31+G(d,p) calculations, the intermolecular structures of double and triple DNA helix formed by Thymine (T) Adenine (A) were fully optimized. Based on analysis of structural parameters, vibrational modes and infrared absorption intensit... see more

Quantitative Structure-Activity Relationship (QSAR) analysis of 1,10-phenantroline analogs as antimalarial drug has been conducted using atomic net charges (q) as predictors of their activity. Data of predictors are obtained from computational chemistry m... see more

Fast and robust image processing and matching is a very important task with various applications in computer vision and robotics. In this paper, we compare the performance of two different image matching techniques, i.e., by speed up robust features and b... see more
