Optimal Linear Combination of Denoising Schemes for Efficient Removal of Image Artifacts
Different denoising schemes show dissimilar types of artifacts. For example, certain transform-based denoising schemes could introduce artifacts in smooth regions while others eli...

A Fast Algorithm for Statistically Optimized Orientation Estimation
Filtering a signal with a finite impulse response (FIR) filter introduces dependencies between the errors in the filtered image due to overlapping filter masks. If the filteri...
