ERRORLESS RESTORATION ALGORITHMS FOR BAND - LIMITED IMAGESPaulo

چکیده
We consider the problem of restoring randomly distributed sets of missing pixels in band-limited discrete images , and give non-iterative and iterative algorithms capable of error-free restoration. The methods discussed have minimum dimension, that is, the size of the matrices and vectors which appear in the algorithm is determined by the number of unknown pixels. This is a characteristic which an alternative iterative formulation , based on the Papoulis-Gerchberg iteration, does not have. Convergence proofs for both the basic algorithms and a number of accelerated iterative methods are included as well. The performance of the methods is demonstrated with examples.

Dual domain interactive image restoration: basic algorithm
This paper describes a new fast, iterative algorithm for interactive image noise removal. Given the locations of noisy pixels and a prototype image, the noisy pixels are to be restored in a natural way. Most existing image noise removal algorithms use either frequency domain information (e.g low pass filtering) or spatial domain information (e.g median filtering or stochastic texture generation...
متن کاملA comparison of errorless and errorful therapies for dysgraphia after stroke.
Despite the increasing significance of written communication, there is limited research into spelling therapy for adults with acquired dysgraphia. Existing studies have typically measured spelling accuracy as an outcome, although speed may also be important for functional writing. As spelling is relatively slow, effortful and prone to errors in people with dysgraphia, minimising errors within t...
متن کاملImage Restoration with Two-Dimensional Adaptive Filter Algorithms
Two-dimensional (TD) adaptive filtering is a technique that can be applied to many image, and signal processing applications. This paper extends the one-dimensional adaptive filter algorithms to TD structures and the novel TD adaptive filters are established. Based on this extension, the TD variable step-size normalized least mean squares (TD-VSS-NLMS), the TD-VSS affine projection algorithms (...
متن کاملA Full Snow Season in Yellowstone : A Database of Restored Aqua Band
The algorithms for estimating snow extent for the Moderate Resolution Imaging Spectroradiometer (MODIS) optimally use the 1.6-μm channel which is unavailable for MODIS on Aqua due to detector damage. As a test bed to demonstrate that Aqua band 6 can be restored, we chose the area surrounding Yellowstone and Grand Teton national parks. In such rugged and difficult-to-access terrain, satellite im...
