Implementation of Separable & Steerable Gaussian Smoothers on an FPGA
<p>Smoothing filters have been extensively used for noise removal and image restoration. Directional filters are widely used in computer vision and image processing tasks such as motion analysis, edge detection, line parameter estimation and texture analysis. It is practically impossible to tune …

Numerical modeling, suppression, and imaging of elastic wave scattering by near-surface heterogeneities
… the spatially varying slope of the noise, using steerable filters, and separating the signal and noise components by applying a directional non-linear filter oriented toward the noise direction to predict the noise and then subtract it from the data. The slope estimation step using steerable …

Automated image-based analysis methods for filament networks structures in two and three dimensions
… F1-score of 0.89. The second relies on using steerable filters and archives F1=0.91-0.92. Additionally, given the graph representation, an algorithm for merging graphs from different focal planes is proposed, yielding a single representation with information from multiple focal planes, …
