A simple image-compression scheme based on the wavelet transform and properties of the human visual system (HVS) is proposed. The scheme attempts to achieve better performance results than those achieved with the well-established JPEG compression technique for very high image-quality levels. To achieve this, the wavelet scheme tries to identify the wavelet(More)
The rank (resp. dimension) of a poset P is the cardinality of a largest (resp. smallest) set of linear orders such that its intersection is P and no proper subset has intersectior: P. Dimension has been studied extensively. Rank was introduced recently by Maurer and Rabinovitch in [4], where the rank of antichains was determined. In this paper we develop a(More)
