Generalized Multiresolution Analysis on Unstructured Grids
Numerische Mathematik, 1999The authors show that the efficiency of high-order essentially non-oscillatory approximations of conservation laws can be improved if ideas of multiresolution analysis (cf. Abgrall and Harten, CAM-reports 93-13, 94-10 and 94-20, University of California, Los Angeles, 1993-1994) are taken in account.These methods of data compression reduce the necessary

Many real-time audio applications perform convolution and correlation operations in the frequency domain for efficiency reasons [114, 134]. The FFT is usually used to transform the time signals back and forth to the frequency domain. Interpreting the FFT operation as a filterbank, the filters have constant bandwidth, and their centre frequencies axe ...

Multiresolution Analysis with Pulses
2002Multiresolution analysis has recently received considerable attention in relation to wavelets. The word “multiresolution” is appropriate in so far as wavelets are local in some sense, and therefore have exponentially decaying impulse response. In image processing it is clear that edges and impulses yield undesirable synthetic features in partially ...

Multiscale and multiresolution analysis
In this chapter, we describe the Gaussian scale-space in the spatial and intensity parameters, and we discuss the scale-selection algorithms for blob and edge detections. Image resolution is to some extent an artifact of the camera used, and with no prior knowledge, we seldomly can predict the size of objects in pixels in images.openaire +2 more sources
