Feature point descriptors: infrared and visible spectra

Sensors (Basel). 2014 Feb 21;14(2):3690-701. doi: 10.3390/s140203690.


This manuscript evaluates the behavior of classical feature point descriptors when they are used in images from long-wave infrared spectral band and compare them with the results obtained in the visible spectrum. Robustness to changes in rotation, scaling, blur, and additive noise are analyzed using a state of the art framework. Experimental results using a cross-spectral outdoor image data set are presented and conclusions from these experiments are given.
