In this paper, we propose a new multi-layered representation technique for image compression, which combine curvelet transform and local DCT in order to benefit from the advantages of each. Curvelet transform is one of the recently developed multiscale transform, which possess directional features and provides optimally sparse representation of objects with(More)
Image compression has been always a very active field of research. A highly efficient numerical scheme is proposed to solve the combined optimization problem posed by the model for separating images into texture and piecewise smooth parts. In the proposed multi-layered image coding schemes, the MCA used in image decomposition is performed using haar wavelet(More)
