This paper proposes a new front propagation method to deal accurately with the challenging problem of tracking non-rigid moving objects. This is obtained by employing a Geodesic Active Region model where the designed objective function is composed of boundary and region-based terms and optimizes the curve position with respect to motion and intensity properties. The main novelty of our approach...

Image segmentation is a fundamental task in image analysis responsible for partitioning an image into multiple sub-regions based on a desired feature. Active contours have been widely used as attractive image segmentation methods because they always produce sub-regions with continuous boundaries, while the kernel-based edge detection methods, e.g. Sobel edge detectors, often produce discontinuo...

Recent studies on program execution behavior reveal that a large amount of execution time is spent in small frequently executed regions of code. Whereas adaptive cache management systems focus on allocating cache resources based on execution access patterns, this paper presents a method of using compiler analysis to manage critical processor resources. With the addition of new architecture tech...

despite of suitable geological and climatic conditions for forming and evolution of alluvial fans and importance of this landform as soil and water resources in arid regions, there are limited studies about this landform in iran. in the present study, evolution and pedogenic development of geomorphic surfaces of an alluvial fan in eastern isfahan were studied by using remote sensing, field and ...

Abstract The composition of interplanetary coronal mass ejections (ICMEs), including the ionic charge states and elemental abundances heavy elements, is tightly correlated with their source regions eruption processes. This can help in analyzing mechanisms plasma origins CMEs, deepen our understanding energetic solar activities. active quiet-Sun have different physical properties; thus, from a s...
