An analysis of wavelet frame based scattered data reconstruction
In real world applications many signals contain singularities, like edges in images. Recent wavelet frame based approaches were successfully applied to reconstruct scattered data from such functions while preserving these features. In this paper we present a recent approach which determines the approximant from shift invariant subspaces by minimizing an `1-regularized least squares problem whic...
متن کاملWavelet frame based scene reconstruction from range data
How to reconstruct the scene (a visible surface) from a set of scattered, noisy and possibly sparse range data is a challenging problem in robotic navigation and computer graphics. As most real scenes can be modeled by piecewise smooth surfaces, traditional surface fitting techniques (e.g. , smoothing spline) generally can not preserve sharp discontinuities of surfaces. Based on sparse approxim...
متن کاملRegularization of Wavelet Based Fitting of Scattered Data — Some Experiments∗ Short Title: Regularization of Wavelet Based Fitting of Scattered Data
In [3] an adaptive method to approximate unorganized clouds of points by smooth surfaces based on wavelets has been described. The general fitting algorithm operates on a coarse–to–fine basis and selects on each refinement level in a first step a reduced number of wavelets which are appropriate to represent the features of the data set. In a second step, the fitting surface is constructed as th...
متن کاملWavelet Frame Based Algorithm for 3D Reconstruction in Electron Microscopy
In electron microscopy, 3D reconstruction is one key component in many computer-ized techniques for solving 3D structures of large protein assemblies using electron microscopy imagesof particles. Main challenges in 3D reconstruction include very low signal-to-noise ratio and very largescale of data sets involved in the computation. Motivated by the recent advances of sparsity-based<...
متن کاملWavelet frame based surface reconstruction from unorganized points
Applications of wavelet frames to image restoration problems (e.g. image deblurring and inpainting) have been successful due to their redundancy and capability of sparsely approximating piecewise smooth functions like images (see e.g. [13, 14, 8]). However, wavelet frames have not yet been used for surface reconstruction problems. Recently in [6], connections between one of the wavelet frame ba...
