Object-based Change Detection Using High-resolution Remotely Sensed Data and Gis
High resolution remotely sensed images provide current, detailed, and accurate information for large areas of the earth surface which can be used for change detection analyses. Conventional methods of image processing permit detection of changes by comparing remotely sensed multitemporal images. However, for performing a successful analysis it is desirable to take images from the same sensor wh...
متن کاملA Strategy of Change Detection Based on Remotely Sensed Imagery and Gis Data
Geometric co-registration errors and results of object extraction (such as classification and pattern recognition) are the two main factors, which greatly affect the results of change detection in traditional methods. Unfortunately, the geometric co-registration accuracy and results obtained by the object extraction methods can not satisfy imagery change detection in practice at present. Consid...
متن کاملObject-oriented Change Detection from Multi-temporal Remotely Sensed Images
An object-oriented change detection algorithm was proposed and experimented to multi-temporal ALOS remotely sensed images. In contrast with conventional pixel-based algorithms, this approach processed homogenous blocks generated by object-oriented image segmentation for change detection. Similar pixels were merged into homogeneous objects by image segmentation at first, and each object (polygon...
متن کاملGenetic Particle Swarm Optimization–Based Feature Selection for Very-High-Resolution Remotely Sensed Imagery Object Change Detection
In the field of multiple features Object-Based Change Detection (OBCD) for very-high-resolution remotely sensed images, image objects have abundant features and feature selection affects the precision and efficiency of OBCD. Through object-based image analysis, this paper proposes a Genetic Particle Swarm Optimization (GPSO)-based feature selection algorithm to solve the optimization problem of...
متن کاملBuilding Detection and Recognition from High Resolution Remotely Sensed Imagery
This paper supposes a schema to deal with the tough task of building detection and recognition from high resolution remotely sensed imagery. It is a region-based and semi-automatic schema combining with Hough transform and computation of convex hull of the pixels contained in the building areas, which can produce a precise result when the contrast between flat building rooftop and the backgroun...
