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 ...

ROAD REGION DETECTION IN URBAN AREAS COMBINING HIGH-RESOLUTION RGB IMAGE AND LASER SCANNING DATA IN A CLASSIFICATION FRAMEWORK
(Copernicus Gesellschaft Mbh, 2013-01-01)
This paper addresses the problem of road region detection in urban areas using an image classification approach. In order to minimize the spectral superposition of the road (asphalt) class with other classes, the Artificial ...

A Note on Gradient-Based Intensity Normalization
(2019-01-01)
This paper presents an improvement on gradient-based intensity normalization introduced by Sintorn et al., which is used in microscopy, especially in the evaluation of proteins and other cell elements in densitometry. In ...
Thermographic analysis of photodynamic therapy with intense pulsed light and needle-free injection photosensitizer delivery: an animal study
(Spie-int Soc Optical Engineering, 2018-01-01)
The photodynamic therapy (PDT) is a therapeutic modality that depends mostly on photosensitizer (PS), light and molecular oxygen species. However, there are still technical limitations in clinical PDT that are under constant ...
A highly accurate level set approach for segmenting green microalgae images
(Universidade Federal da Bahia - UFBAIntelligent Vision Research Lab – iVisionSalvador, 2015-08)
We present a method for segmenting 2D microscopy images of freshwater green microalgae. Our approach is based on a specialized level set method, leading to efficient and highly accurate algae segmentation. The level set ...
Velocity estimation of a mobile mapping vehicle using filtered monocular optical flow
(2007-01-01)
Generally, a road image sequence acquired by a mobile mapping system (MMS) is oriented by integrating the Global Positioning System (GPS) and an inertial navigation system (INS) data. Alternatively, this article presents ...
3D markup of radiological images in ePAD, a web-based image annotation tool
(Institute of Electrical and Electronics Engineers – IEEEUniversidade de São Paulo - USPSão Carlos e Ribeirão Preto, 2015-06)
Quantitative and semantic information about medical images are vital parts of a radiological report. However, current image viewing systems do not record it in a format that permits machine interpretation. The ePAD tool ...
Analysis of Features for Breast Cancer Recognition in Different Magnifications of Histopathological Images
(2020-07-01)
Breast cancer is one of the most common diseases in women in the world. There are various imaging techniques employed in the diagnosis. The histological image analysis supported by computational systems has proved to be ...
