Automatic Crowd Analysis from Very High Resolution Satellite Images
Recently automatic detection of people crowds from images became a very important research field, since it can provide crucial information especially for police departments and crisis management teams. Due to the importance of the topic, many researchers tried to solve this problem using street cameras. However, these cameras cannot be used to monitor very large outdoor public events. In order ...
متن کاملObject-Oriented Method for Automatic Extraction of Road from High Resolution Satellite Images
As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...

متن کاملAutomatic Building Extraction from High Resolution Stereo Satellite Images
An approach was developed for automatic building extraction from high resolution stereo satellite images. The approach utilizes the spectral properties of the pan-sharpened multispectral bands and the elevation model generated from the stereo panchromatic bands. First, the pan-sharpened multispectral bands are classified using the Maximum Likelihood Classifier (MLC) to separate the buildings fr...
متن کاملAutomatic GIS Updating from High Resolution Satellite Images
Among all the issues involved in Geographic Information Science, automating the update of 2D building databases is a crucial and challenging issue. Such an update usually starts out with a manual change detection process. The main goal of this paper is to present a new method to automate the detection of changes in a 2D building database, starting from satellite images. The workflow of our appr...
