Pyramidal directional filter banks and curvelets
A flexible multiscale and directional representation for images is proposed. The scheme combines directional filter banks with the Laplacian pyramid to provides a sparse representation for twodimensional piecewise smooth signals resembling images. The underlying expansion is a frame and can be designed to be a tight frame. Pyramidal directional filter banks provide an effective method to implem...
متن کاملImplementational Aspects of the Contourlet Filter Bank and Application in Image Coding
This paper analyzed the implementational aspects of the contourlet filter bank (or the pyramidal directional filter bank (PDFB)), and considered its application in image coding. First, details of the binary tree-structured directional filter bank (DFB) are presented, including a modification to minimize the phase delay factor and necessary steps for handling rectangular images. The PDFB is view...

متن کاملA low complexity overcomplete directional image pyramid
We present an undecimated directional filter bank (UDFB) derived from the DFB originally proposed by Bamberger and Smith. The new UDFB has excellent orientation selectivity, and maintains the low computational complexity from its predecessor. While overcomplete, the UDFB presents other properties like shift invariance, desirable for some image analysis applications. Using ladder structures the ...
متن کاملSpeckle Reducing Contourlet Transform for Medical Ultrasound Images
Speckle noise affects all coherent imaging systems including medical ultrasound. In medical images, noise suppression is a particularly delicate and difficult task. A tradeoff between noise reduction and the preservation of actual image features has to be made in a way that enhances the diagnostically relevant image content. Even though wavelets have been extensively used for denoising speckle ...
