Remove a solid background from an image using grayscale thresholding, then write a BGRA PNG with an alpha mask. ./build/bg-cutout fixtures/sample.jpg output.png ./build/bg-cutout -i photo.jpg -o ...

This repository implements and compares several optimization methods for regularized logistic regression, with a focus on stochastic algorithms, proximal regularization, and sparse models. The code is ...

Abstract: In this letter we revisit the problem of smoothed nonparametric spectral estimation via cepstrum thresholding. We formulate the problem of cepstrum ...

Abstract: Anomaly detection in multivariate time series is a critical research area, but it is also a challenging one due to its occurrence in various real-world scenarios, such as structural health ...
