A Novel Change Detection Framework in Urban Area Using Multilevel Matching Feature and Automatic Sample Extraction Strategy

Automatic Urban Feature Extraction Using Mathematical Morphology

Manual method of feature extraction from remote sensing imagery is a tedious and time-consuming process. The current paper presents the application of Mathematical Morphology for extracting urban features like buildings and roads from remotely sensed imagery. Roads and Buildings are the major features that influence urban planning and development. Also, GIS databases are to be frequently update...

Automatic Open Space Area Extraction and Change Detection from High Resolution Urban Satellite Images

In this paper, we study efficient and reliable automatic extraction algorithm to find out the open space area from the high resolution urban satellite imagery, and to detect changes from the extracted open space area during the period 2003, 2006 and 2008. This automatic extraction and change detection algorithm uses some filters, segmentation and grouping that are applied on satellite images. T...

Change Detection in Urban Area Using Decision Level Fusion of Change Maps Extracted from Optic and SAR Images

The last few decades witnessed high urban growth rates in many countries. Urban growth can be mapped and measured by using remote sensing data and techniques along with several statistical measures. The purpose of this research is to detect the urban change that is used for urban planning. Change detection using remote sensing images can be classified into three methods: algebra-based, transfor...

Feature Extraction and Matching as Signal Detection

Automatic Road Detection and Extraction From MultiSpectral Images Using a New Hierarchical Object-based Method

Road detection and Extraction is one of the most important issues in photogrammetry, remote sensing and machine vision. A great deal of research has been done in this area based on multispectral images, which are mostly relatively good results. In this paper, a novel automated and hierarchical object-based method for detecting and extracting of roads is proposed. This research is based on the M...
