Research ArticleOpen accessIn the abstractImaging Spectroscopy and Light Detection and Ranging Data Fusion for Urban Features ExtractionMohammed Idrees, Helmi Zulhaidi Mohd Shafri, Vahideh SaeidiThis study presents our findings on the fusion of Imaging Spectroscopy (IS) and LiDAR data for urban feature extraction. We carried out necessary preprocessing of the hyperspectral image. Minimum Noise Fraction (MNF) transforms was used for ordering hyperspectral bands according to their noise. Thereafter, we employed Optimum Index Factor (OIF) to statistically select the three most appropriate bands combination from … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 28 Oct 2013 · 7,161 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRepresentation of Polygonal Surfaces as Displaced Subdivision SurfacesMuhammad HussainProblem statement: Displaced subdivision representation possesses a number of attractive features for efficient and convenient processing tasks like editing, geometry compression, animation, scalability and adaptive rendering of polygonal models. In this representation, a detailed surface model was built as a scalar-valued displacement map over a smooth domain surface. The construction of the smooth domain surface from a polygonal model was … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 6,857 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Tactile Sensor for Detection of Skin Surface Morphology and its Application in Telemedicine SystemsRoozbeh Khodambashi, Siamak Najarian, Ali Tavakoli Golpaygani et al.We proposed a new type of tactile sensor that is capable of determining the surface morphology of skin lesions. The sensor consists of a brass cylinder with an axial bore. Three peripheral bobbins were machined in the cylinder around which three coils have been wound. An iron core can easily move inside the bore. One of the coils acts as … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,263 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnaphora Resolution in Thai EDU SegmentationAuthapon Kongwan, Siti Sakira Kamaruddin, Farzana Kabir AhmadHuman knowledge is mostly in the form of unstructured text. Text can be transcribed into various languages such as the Thai language. To extract knowledge from Thai text, natural language tasks such as word segmentation, Elementary Discourse Unit (EDU) segmentation, and anaphora resolution is the needed tasks. Some interesting phenomena such as non-referential anaphora and the ellipsis of the owner … …Journal of Computer Science, Vol. 18, Issue 4 · 5 May 2022 · 6,068 accessesView PDF Cite
