We analyze the use of Haar wavelets in classification and clustering of 4D spatiotemporal fMRI motor data, comparing our results with previous studies that applied wavelets to motor task data as well as other techniques that have been previously applied to the same dataset, including voxelwise spatial k-means clustering and classification by subject based on time series analysis. Subject-based ...

The purpose of this paper is to give a very short, \nuts and bolts", introduction to the lifting scheme and provide references for further reading. The lifting scheme is a new method for constructing biorthogonal wavelets. The main di erence with classical constructions [1-3] is that it does not rely on the Fourier transform. This way lifting can be used to construct second generation wavelets,...
