Histogram Layers for Synthetic Aperture Sonar Imagery

8 Sep 2022  ·  Joshua Peeples, Alina Zare, Jeffrey Dale, James Keller ·

Synthetic aperture sonar (SAS) imagery is crucial for several applications, including target recognition and environmental segmentation. Deep learning models have led to much success in SAS analysis; however, the features extracted by these approaches may not be suitable for capturing certain textural information. To address this problem, we present a novel application of histogram layers on SAS imagery. The addition of histogram layer(s) within the deep learning models improved performance by incorporating statistical texture information on both synthetic and real-world datasets.
