Fractal analysis of eroded surfaces by digital image processing
(Elsevier B.V., 2002-10-01)
Jet impingement erosion test rig has been used to erode titanium alloy specimens (Ti-4Al-4V). Eroded surface profiles have been obtained by vertical sectioning method for light microscopy observation. Mixed fractals have ...

Classification of polymers insulators hydrophobicity basead on digital image processing
(ABM, ABC, ABPol, 2012)
Although the hydrophobicity is usually an arduous parameter to be determined in the field, it has been pointed out as a good option to monitor aging of polymeric outdoor insulators. Concerning this purpose, digital image ...
Dynamic multiple-image encryption based on chirp z-transform
(IOP Publishing, 2019-02)
It is demonstrated a dynamic encryption scheme based on chirp − z transform (CZT). The novel design of this setup allows to protect multiple images in a multiplexed format and fully recover them without the influence of ...
STREET REGION DETECTION FROM NORMALIZED DIGITAL SURFACE MODEL AND LASER DATA INTENSITY IMAGE
(Copernicus Gesellschaft Mbh, 2011-01-01)
The urban road network extraction process can be simplified by firstly detecting regions corresponding to streets, allowing a substantial reduction of the search area. As a result, the extraction process is benefited in ...
