Abstract
In this paper we tackle the problem of detecting sources of combustion in high definition multispectral Medium Wavelength InfraRed (MWIR) (3-5?m) images. We present a novel approach to this problem consisting in processing the images block-wise using a new technique that we call Supervised Principal Component Analysis (SPCA) to get the components of these blocks. This outperforms state-of-the-art methods with a significant reduction in the complexity of the whole scheme. As a classifier, we propose the use of a Support Vector Machine (SVM) comparing the results from both its novelty-detection and binary non-linear versions. High performance is achieved from a small set of components.
