Pedestrian detection in infrared images [PDF]

IEEE IV2003 Intelligent Vehicles Symposium. Proceedings (Cat. No.03TH8683), 2004
This paper describes an approach for pedestrian detection in infrared images. The developed system has been implemented on an experimental vehicle equipped with an infrared camera and preliminarily tested in different situations. It is based on the localization of warm symmetrical objects with specific size and aspect ratio; since also road ...

INFRARED IMAGING DEVICES IN INFRARED MEDICAL RADIOGRAPHY [PDF]

Annals of the New York Academy of Sciences, 1964
The word “thermograph” often used to describe both an instrument and the product of that instrument has as its roots the Greek words thermos and gruphos. The latter means a sketch or pictorial representation; thus, the graphic arts, scientific graphs, photographs, etc. The former relates to heat or temperature.

Infrared Imaging

, 2009
A mid‐infrared mission would enable the detection of biosignatures of Earth‐like exoplanets around more than 150 nearby stars. The mid‐infrared spectral region is attractive for characterizing exoplanets because contrast with the parent star brightness is more favorable than in the visible (10 million vs.
