MAN-MADE OBJECT EXTRACTION FROM REMOTE SENSING IMAGERY BY GRAPH-BASED MANIFOLD RANKING
Man-made Object Extraction Remote Sensing Image Priori Area Extraction Graph Model Manifold Ranking
2018/5/14
The automatic extraction of man-made objects from remote sensing imagery is useful in many applications. This paper proposes an algorithm for extracting man-made objects automatically by integrating a...
A FUSION METHOD OF SAR AND OPTICAL IMAGES FOR URBAN OBJECT EXTRACTION
Satellite remote sensing Sharpening Image understanding Fusion Land cover
2015/12/31
A new image fusion method of SAR, Panchromatic (Pan) and multispectral (MS) data is proposed. First of all, SAR texture is extracted by ratioing the despeckled SAR image to its low passapproximation, ...
SEGMENTATION AND OBJECT EXTRACTION FROM ANISOTROPIC DIFFUSION FILTERED LIDAR INTENSITY DATA
LiDAR Intensity Image Anisotropic Diffusion Segmentation Object-Based Classification
2015/8/19
LiDAR technology provides two different kinds of data: elevation, obtained by differences in time of the emitted and received laser signal; and intensity, obtained by differences of reflected laser be...
