چکیده

Transform learning has been introduced and studied in [1],[2], [3] and [4]. An optimal transform learning for structured and overcomplete matrix was proposed in [5]. However, several issues (optimality, convergence and computational complexity) related to learning an incoherent, well-conditioned, non-structured and overcomplete sparsifing transform still remain open. Let X ∈ N) has the following form:

Learning Overcomplete Signal Sparsifying Transforms

I. TRANSFORM LEARNING The formulations for learning synthesis [1] and analysis [2], [3] sparsifying dictionaries are typically non-convex and NP-hard, and the approximate algorithms are still computationally expensive. As an alternative, we recently introduced an approach for learning square sparsifying transforms W ∈ Rm×n, m = n [4], which are competitive with overcomplete synthesis or analysi...

Compressed sensing MRI with combined sparsifying transforms and smoothed l0 norm minimization

Undersampling the k-space is an efficient way to speed up the magnetic resonance imaging (MRI). Recently emerged compressed sensing MRI shows promising results. However, most of them only enforce the sparsity of images in single transform, e.g. total variation, wavelet, etc. In this paper, based on the principle of basis pursuit, we propose a new framework to combine sparsifying transforms in c...

ℓ0 Sparsifying Transform Learning with Efficient Optimal Updates and Convergence Guarantees

Many applications in signal processing benefit from the sparsity of signals in a certain transform domain or dictionary. Synthesis sparsifying dictionaries that are directly adapted to data have been popular in applications such as image denoising, inpainting, and medical image reconstruction. In this work, we focus instead on the sparsifying transform model, and study the learning of well-cond...

Learning Filter Bank Sparsifying Transforms

Data is said to follow the transform (or analysis) sparsity model if it becomes sparse when acted on by a linear operator called a sparsifying transform. Several algorithms have been designed to learn such a transform directly from data, and data-adaptive sparsifying transforms have demonstrated excellent performance in signal restoration tasks. Sparsifying transforms are typically learned usin...

Analysis of Fast Alternating Minimization for Structured Dictionary Learning

Methods exploiting sparsity have been popular in imaging and signal processing applications including compression, denoising, and imaging inverse problems. Data-driven approaches such as dictionary learning enable one to discover complex image features from datasets and provide promising performance over analytical models. Alternating minimization algorithms have been particularly popular in di...
