Hierarchical and spatial structures for interpreting images of man made scenes using graphical models
Hierarchical and Spatial Structures for Interpreting Images of Man-made Scenes Using Graphical Models The task of semantic scene interpretation is to label the regions of an image and their relations into meaningful classes. Such task is a key ingredient to many computer vision applications, including object recognition, 3D reconstruction and robotic perception. It is challenging partially due ...
متن کاملDetection of Man-made Structures in Natural Images
Object detection in images is a very active research topic in many disciplines. Probabilistic methods have been applied to the problem with varying degrees of success. A logistic classifier, Markov random field (MRF), and discriminative Random Field (DRF) were used for the detection of man-made structures in natural images. It was found that the MRF and DRF models were often improvements over t...
متن کاملDetecting Changes in Aerial Views of Man-Made Structures
An important application of machine vision is to provide a means to monitor a scene over a period of time and report significant changes. Comparing intensity values of successive images is not effective as such changes don’t necessarily reflect actual changes at a site but might be caused by changes in the view point and illumination. We also want to ignore seasonal changes and focus on structu...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
analysis of ruin probability for insurance companies using markov chain
در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
