Active contours, or snakes, are computer-generated curves that move within images to find out salient image structures like object boundaries. Energy based formulations using a level set approach have been successfully used to model the snake evolution. The Euler-Lagrange equation associated to such energies yields to partial differential equations (PDE) which are usually solved using level set...

Bangladesh is one of the climate risk-prone countries in South Asia facing tremendous challenges to combat sea-level rise and its associated coastal morphological changes. This study aimed determine interaction changes, particularly at Cox’s Bazar Kutubdia Island along eastern coast Bangladesh. Available hourly tide gauge data, daily temperature, rainfall 15 LANDSAT satellite images for period ...

Morphological, numerical and chemical taxonomy of the genus Crataegus was studied in the East and northeast of Iran. More than 80 fresh specimens as well as 50 herbarium specimens from different localities were examind. Using vegetative and reproductive morphological characters an identification key is provided for all taxa. For numerical taxonomy 85 morphological characters were measured and t...
