GOMEZ VARGAS, Ernesto; OBREGON NEIRA, Nelson  e  ROCHA ARANGO, Diego Fernando. Cloud segmentation methods applied to satellite images. Tecnura [online]. 2013, vol.17, n.36, pp.96-110. ISSN 0123-921X.

The goal of this paper is to show the results of implementing two cloud segmentation techniques on GOES (satellite images). The first technique is based on regions and gray-level thresholding. The second technique is based on boundaries and the Hough transform. Finally, the results of our experiments (with the two segmentation methods) are compared with results from segmented imaging obtained from specialized software packages, where spectral band separation is applied using the information interest.

Palavras-chave : image processing; segmentation; Hough transform; gray levels thresholding.
