Shadow detection and removal is an important task when dealing with colour outdoor images. Shadows are generated by a local and relative absence of light. Shadows are, first of all, a local decrease in the amount of light that reaches a surface.

This paper is concerned with the derivation of a progression of shadow-free image representations. First we show that adopting certain assumptions about lights and cameras leads to a 1-d, grey-scale image representation which is illuminant inva

For this project, the shadow removal method used by Finlayson et al. in [1] was implemented. This report contains an overview of the mathematical background and a detailed discussion on the experiments performed with the implementation. This me
