Anisotropic scattered data interpolation for pushbroom image rectification

Ringaby, Erik; Friman, Ola; Forssén, Per-Erik; Opsahl, Thomas Olsvik; Haavardsholm, Trym Vegard; Kåsen, Ingebjørg (2014)

This paper deals with fast and accurate visualization of pushbroom image data from airborne and spaceborne platforms. A pushbroom sensor acquires images in a line-scanning fashion, and this results in scattered input data ...
Compact camera for multispectral and conventional imaging based on patterned filters

Skauli, Torbjørn; Torkildsen, Hans Erling; Nicolas, Stephane; Opsahl, Thomas Olsvik; Haavardsholm, Trym Vegard; Kåsen, Ingebjørg; Rognmo, Atle (2014)

A multispectral camera concept is presented. The concept is based on using a patterned filter in the focal plane, combined with scanning of the field of view. The filter layout has stripes of different bandpass filters ...
Real-time anomaly detection in hyperspectral images using multivariate normal mixture models and GPU processing

Tarabalka, Yulija; Haavardsholm, Trym Vegard; Kåsen, Ingebjørg; Skauli, Torbjørn (2009)

Hyperspectral imaging, which records a detailed spectrum of light arriving in each pixel, has many potential uses in remote sensing as well as other application areas. Practical applications will typically require real-time ...
