A Tale of Two Bases: Local-Nonlocal Regularization on Image Patches with Convolution Framelets

4 Jun 2016Rujie YinTingran GaoYue M. LuIngrid Daubechies

We propose an image representation scheme combining the local and nonlocal characterization of patches in an image. Our representation scheme can be shown to be equivalent to a tight frame constructed from convolving local bases (e.g. wavelet frames, discrete cosine transforms, etc.).. (read more)
