چکیده
Using snakes to extract buildings from satellite imagery such as IKONOS and Quickbird is an active activity in remote sensing society. Building extraction from satellite imagery has more than 20 years of history but the automated extractions are still undergoing developmental stages due to increasing image variation, required level of details and higher resolution imagery are acquired. This paper discusses the prototyping of an improved snake model. Snake is initialized in cornered-radial cast in comparison to the existing centered-radial. Moreover the coefficients for snake energy are obtained through genetic algorithm. Key-Words: Snake contour, satellite imagery, genetic algorithm, building extraction.
