Multichannel wavelet scheme for color image processing

Every day massive quantities of two-dimensional documents are produced, stored and transmitted. Digital color images are the most prominent type of data in this category. To process these objects a variety of powerful and sophisticated wavelet-based schemes have been developed and implemented. Considering that digital color images are vector objects with three components, they can be suitably processed in the context of a multichannel Multi Resolution Analysis. In this work we focus on a new vector approach to multichannel wavelet analysis of color images based on several classes of full rank filters, showing the results of a wide experimentation.
