Ishikawa, A. S. [UNESP]; Silva, E. A. [UNESP]Made available in DSpace on 2022-04-28T19:00:54Z (GMT). No. of bitstreams: 0 Previous issue date: 2010-01-01; This paper seeks to apply routine for highways detection through the mathematical morphology tools in high resolution image. The Mathematical Morphology theory consists of describing structures geometric presents quantitatively in the image (objectives or features). This explains the use of the Mathemat...

Statella, T.; Pina, P.; Silva, E. A. [UNESP]; Nervis Frigeri, Ary Vinicius; Gallon Neto, FredericoMade available in DSpace on 2018-11-26T15:31:26Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-10-15; We have calculated the prevailing dust devil tracks direction as a means of verifying the Mars Climate Database (MCD) predicted wind directions accuracy. For that purpose we have applied an automatic method based on morphological openings for inferring the prevailing tracks direction in a dataset compri...
Calculation of areas flooded in urban reservoirs of water supply
Silva, E. A. [UNESP]; Leonardi, F. [UNESP]; Pedrosa, M. M. [UNESP]; Puga, F. [UNESP]; Leonardi, V. S. S. [UNESP]; Liu, Y. M.; Fu, D.; Tong, Z. X.Made available in DSpace on 2018-11-26T15:31:37Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-01-01; In 2014, Brazil suffered a long drought period. The unusual lack of rainfall has resulted in a decrease in the water levels over the main reservoirs in the country. In this sense, images from remote sensing and techniques of digital image processing can be used as a tool to monitor the water level decre...

No. of bitstreams: 0 Previous issue date: 2015-01-01; FCT/UNESP has been developing CARTOMORPH to be a public domain software which can be operated by users needing to extract and/or detect features from digital images. In this work, two methods were applied for the extraction and/or detection of the contours of the feature of interest (the highway) using ...
Assessment of surface water at the Sobradinho reservoir under the effects of dr...
Silva, E. A. [UNESP]; Pedrosa, M. M. [UNESP]; Azevedo, S. C. [UNESP]; Cardim, G. P. [UNESP]; Carvalho, F. P.S. [UNESP]Made available in DSpace on 2018-12-11T17:04:33Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-01-01; The matrix of energy generation in Brazil is predominantly hydroelectric power. Consequently, the reservoirs need constant monitoring due to the large volume of artificially dammed water. Images from remote sensing can provide reliable information concerning water bodies. In this paper, we use remote se...
