LOCAL DESCRIPTORS BASED ON COLOR IMAGES
2009
This paper investigates local descriptor methods utilizing color images instead of grayscale images to improve the uniqueness of the local descriptors. A color model was utilized in order to be invariant to illumination condition changes. Two local descriptor methods, namely color local descriptor and hybrid local descriptor methods, were developed. Results from the experiments conducted show that these methods are more robust against a variety of image transformation and illumination condition changes compared to existing methods.
