An Initial Study on Vehicle Information Extraction from Single Pass QuickBird Satellite Imagery
Vehicle information is useful in many fields. In this paper, a technique is presented to extract vehicle information from single pass QuickBird images. While passing a target area, the satellite acquires panchromatic (PAN) and multi-spectral (MS) images simultaneously. Because of a small time interval difference between the PAN and MS images, it is theoretically possible to extract two sets of ...
متن کاملtransference of imagery: a comparative formalistic study of shakespeares hamlet and its two persian translations
هدف از این تحقیق بررسی انتقال صور خیال هملت در دو ترجمه ی فارسی آن از نظر فرمالیستی بود. برای بدست آوردن داده-های مورد نیاز، 130 نمونه استعاره، مجاز، ایهام، کنایه و پارادوکس در متن اصلی مشخص شده و سپس بر اساس مدل نیومارک (1998) برای ترجمه ی استعاره یا بطور کلی زبان مجاز با معادل های فارسی شان مقایسه گردیدند. این تحقیق بر آن بود تا روش های استفاده شده برای ترجمه هر کدام از انواع زبان مجاز ذکر شد...
15 صفحه اولExtraction of Buildings from Quickbird Imagery – What Is the Relevance of Urban Context and Heterogeneity?
The high frequency and scope of spatial changes in cities demands ways of expediting the production and updating of large-scale geographic information. For that purpose, current and future very high spatial resolution satellite imagery (VHR) and semiautomated object-based image analysis methods may be an advantageous alternative to classical data sources and methods, i.e., aerial photography an...
متن کاملExtraction of Buildings from QuickBird Imagery for Municipal Use – the Relevance of Urban Context and Heterogeneity
Lisbon is both a historical and modern city having a dynamic landscape, where increasingly diverse urban forms and materials coexist. This complex reality is possibly causing the feature extraction process from imagery to become more challenging. This study tests the semiautomated extraction of buildings from a QuickBird image in urban areas with different characteristics, and explores the impa...
متن کاملExtraction of Lakes from Satellite Imagery
We address the problem of finding the bounding contour of a lake in high-resolution satellite imagery. The proposed solution consists of a novel approach for probabilistic contour grouping when some prior (possibly rough) knowledge about the lake is known. Such knowledge is available, for example, from an existing GIS. The grouping process is based on a Bayesian approach and a constructive algo...
