2014 We derive the weak disorder expansion of the Lyapounov exponents of a product of random matrices. The condition for this expansion to be valid is that in the limit of zero disorder, the matrix has all its eigenvalues with different moduli. As an example we study the problem of localisation on strips in the limit of weak disorder. We show that our(More)
In this paper we present a new class of reconstruction algorithms that are basically different from the traditional approaches. We deviate from the traditional technique which treats the pixels of the image as point samples. In this work, the pixels are treated as rectangular surface samples. It is in conformity with image formation process, in particular(More)
