Neural network recognizing 3-dimensional object through ultrasonic scattering waves

With the goal of recognizing and faithfully reconstructing objects using ultrasonic waves, the authors devised a system which combines existing acoustic holography with neural networks. The merits of this system is its ability to analyze rather vague ultrasonic waves received by an array of receivers and then to faithfully reconstruct the image. The first step in this research has been the recognition of planar objects
