Image Analysis of Remotely Sensed Images
نویسنده
چکیده
different regions [3]. Given a digitized image containing several objects, the image classification process consists of three major phases. AbstractThe analysis of a remote sensing image usually requires the comparison of the analyzed image with another image taken from the same spot. In an automated object identification system for remotely sensed images, thresholding techniques are used to analyze the images. Color values and solidity features are used for object identification. In this project, the objects identified are catfish ponds. Results prove that automatic image analysis provides a good means to extract catfish ponds from remotely sensed images.

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...
