Uydu Görüntülerinin Yüksek Performansta İşlenmesi Üzerine Bir İnceme: Vektör Tabanlı Mozaik Örme Durum Çalışması

Uydu, uzaktan algılama, uydu görüntülerinin yüksek performansta işlenmesi ve farklı uydu sensörlerinden elde edilen uydu görüntülerinden nesne çıkarım çalışmaları son yıllarda popüler bir konu olmuştur. Ülkemizde de ilk yerli alçak yörünge (700 kilometre civarında) uyduları Göktürk2 ve RASAT’ın kurulmasının ardından Ay’a derin gözlem uydusu göndermek de 2023 hedefleri arasında yer almaktadır. İlgili gelişmelerle beraber uydu … Read more Uydu Görüntülerinin Yüksek Performansta İşlenmesi Üzerine Bir İnceme: Vektör Tabanlı Mozaik Örme Durum Çalışması

An Approach For Stitching Satellite Images in a Bigdata Mapreduce Framework

In this study we present a two-step map/reduce framework to stitch satellite mosaic images. The proposed system enable recognition and extraction of objects whose parts falling in separate satellite mosaic images. However this is a time and resource consuming process. The major aim of the study is improving the performance of the image stitching processes … Read more An Approach For Stitching Satellite Images in a Bigdata Mapreduce Framework

Tiling of Satellite Images to Capture an Island Object

Abstract. This study proposes a novel tiling approach to capture an image of an entire object. Multi-spectral and multi-temporal satellite images are obtained a priori, and these individual image pieces can then be joined together at a later date to form an image of the entire object. The effectiveness of the proposed technique has been … Read more Tiling of Satellite Images to Capture an Island Object

Resource- and content-aware, scalable stitching framework for remote sensing images

Abstract This paper proposes a new approach to solving the scalability problem in stitching and registration of satellite images. The image stitching process is mostly utilized to capture an image of an entire object, whose parts fall in separate but overlapping mosaics. Due to their high resolutions and huge sizes, the stitching of satellite mosaic … Read more Resource- and content-aware, scalable stitching framework for remote sensing images

An automated technique to determine spatio-temporal changes in satellite island images with vectorization and spatial queries

Abstract. For spatio-temporal and topologic analyses, vectorial information (car- rying coordinate values defined as point sets) gives better information than its raster (grid of pixels) counterpart. The study presented in this paper is based on (i) recogni- tion and extraction of an island object in a set of digital images captured by LandSat-7 satellite and … Read more An automated technique to determine spatio-temporal changes in satellite island images with vectorization and spatial queries
