DOI: 10.1109/tcsii.2020.2980557
Abstract: This brief studies the redundancy in the image processing pipeline for histogram of oriented gradients (HOG) feature extraction. The impact of demosaicing on the extracted HOG features is analyzed and experimented. It is shown that… read more here.

DOI: 10.1109/tim.2023.3276530
Abstract: This article presents a novel approach for sensorless speed measurement of induction motors (IMs) using a time-domain stator current analysis. More particularly, we propose the use of histogram of oriented gradients (HOGs), usually applied to… read more here.
