Ridge-based fingerprint matching using hough transform
(Institute of Electrical and Electronics Engineers (IEEE), Computer Soc, 2005-12-01)
Despite the efficacy of minutia-based fingerprint matching techniques for good-quality images captured by optical sensors, minutia-based techniques do not often perform so well on poor-quality images or fingerprint images ...
Simplified wide dynamic range CMOS image sensor with 3t APS reset-drain actuation
(Universidade Federal de Minas GeraisUFMG, 2014-07-31)
An image sensor is an array of small light-sensitive cells called pixel sensors. A pixel, or picture pix element el, is the smallest unit of an image. Therefore a pixel sensor is the smallest cell of an image sensor, which ...
Desenvolvimento de um sensor de baixo custo e descartável para o monitoramento de odor
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Biotecnologia - PPGBiotecCâmpus São Carlos, 2015-02-26)
The research proposal was found low cost alternative solution to automatize the
classification and selection process to recognize fruit ripeness level using biologic
behavior instead of human visual inspection. The goal ...
Automatic shadow segmentation in aerial color images
(2003-01-01)
A robust and efficient technique to segment shaded areas in aerial color images is presented here. This technique is based on the physical phenomenon of atmospheric dispersion of the sunlight most well known as the Rayleigh ...

Comparison of panoramic stereoscopic sensors based on hyperboloidal mirrors
(IEEE, 2009)
Panoramic distance maps can provide valuable information for mobile robot navigation. An approach to obtain such distance maps is to implement a stereoscopic system using two hyperboloidal catadioptric sensors. This paper ...
A feasibility study on incremental bundle adjustment with fisheye images and low-cost sensors
(2019-01-01)
Low cost imaging and positioning sensors are opening new frontiers for applications in near real-time Photogrammetry. Omnidirectional cameras acquiring images with 360° coverage, when combined with information coming from ...
