A sub-pixel and multispectral corner detector

Proposes in a corner detector algorithm, which leads to results both on mono-spectral and multispectral images. To validate the method, we compare its mono-spectral version to the Harris detector, which is the most frequently used in literature. This study shows that the proposed method gives generally more efficient results. However, bad localisations appear for very blurred images (as for most corner detectors). Therefore, we have implemented a sub-pixel detector able to find the exact corner position
