The application of the wavelet transform in image processing is most frequently based on a separable transform. Lines and columns in an image are treated independently and the basis functions are simply products of corresponding onedimensional functions. Such a method keeps simplicity in design and computation. In this paper, a new two-dimensional approach is proposed, which retains the simplicity of separable processing, but allows more directionalities. The method can be applied in many areasdoi:10.1109/icip.2002.1039039 dblp:conf/icip/DragottiVV02 fatcat:2i2zbpjg4rddxhsq7f6t5yxjwi
