Statistical methods are usually applied in the processing of digital images for the analysis of the textures displayed by them. Aiming to evaluate the urbanization of a given location from satellite or aerial images, here we consider a simple processing to distinguish in them the “urban” from the “rural” texture. The method is based on the mean values and the standard deviations of the colour t...
This paper reports on visual obstacle detection from a monocular camera for autonomous vehicles. By leveraging a textured prior map, we propose a probabilistic formulation for finding the optimal image partition that separates obstacles from groundplane. Our key insight is the use of a prior map that enables ground appearance models conditioned on prior map texture and a probabilistic optical f...
Background and Aim: Promoting health and responding to the health needs of people and communities is the most important mission of any country's health system.In recent years،the concept of health and its determinants and on the other hand the health needs and demographic structure of societies have undergone many changes. Fair access to High quality health care seems impossible without formul...
Applying computer vision technology to IR (Infra-Red) images for UAV (Unmanned Aerial Vehicle) applications is difficult due to its characteristics which differ from common image processing. By combining visual categorization with low level IR image processing, this paper presents a framework for automatic labeling of IR images in probabilistic manner. We extract the features which contain temp...
This paper is an overview of the AVENUE project at Columbia University. AVENUE's main goal is to automate the site modeling process in urban environments. The rst component of AVENUE is a 3-D modeling system which constructs complete 3-D geometric models with photometric texture mapping acquired from di erent viewpoints. The second component is a planning system that plans the Next-BestView for...
Background and Objectives: Burns are tragic events with considerable mortality rates. This study was conducted to analyze the spatial pattern of burns and identify the factors associated with the burn injuries in Mashhad, Iran. Methods: This retrospective cross-sectional study was conducted in patients hospitalized in Imam Reza Hospital Burn Center, Mashhad, which is the only referral burn ...
Over the past 50 years, while the development of intermediate texture of Tehran has focused on spatial dimension and physical structure, neglecting the user experience and social dimensions has become a design challenge. This paper has focused on Social interaction in public space neighborhood via integration of social and spatial dimensions which is essential more than ever. In this paper, a r...
