Paper Abstract

In the recent past years, innumerable techniques more complex than the others have emerged in computer vision. They have been applied to many fields and, thanks to the tremendous computational power one has access to nowadays, have made possible more and more elaborate applications. In this article, we propose a classification tool, using hand-crafted interpretable (statistical and digital imaging) features, in order to confirm or invalidate the presence of passengers on skilift vehicles in moutain ranges. More precisely, Linear Discriminant Analysis, which is a dimensionality reduction alongside classification technique, and its less restrictive variant Quadratic Discriminant Analysis, are applied. One of the paper’s objectives consists in illustrating the famous law of parsimony, also known as Occam’s razor, in the sense that the simpler solutions should be considered first and more complex models should be built afterwards if needed.
