A signal feature extraction method based on Hough transform
Luwei Zhang, Jiawei Wang, Lijun Wan, Dongming Li · 2023
The image processing method is used to extract the target trajectory and signal features. This paper improves the traditional image processing method Hough transform, uses the Canny operator to detect the contour, and improves the traditional Hough transform by decomposing the signal features and time iteration. It can extract irregular trajectory targets and extract signal frequency domain features. At the end of this paper, experimental data proves that the improved Hough transformation method can meet the stable extraction of irregular curve trajectories and cross trajectories, and can also perform feature localization and feature extraction on feature signals.
