Convolutional Neural Network Reference for Track-Before-Detect Applications

Abstract

TBD (Track-Before-Detect) algorithms allow the detection and tracking of objects of which the signal is lost in the background noise. The use of convolutional neural networks (ConvNN) allows to obtain more effective algorithms than the previous, because it is possible to take into account the background as well as the spatial and temporal characteristics of the tracked object signal. The article presents solutions for taking into account the motion with variable trajectory and speed through segmental interpolation and rectification of the trajectory, which allows the effective convolutional implementation of the TBD algorithm. The boundary of object detection was determined depending on the number of pixels of the object in relation to the number of pixels of the image stack and signal strength for the simplest neural network, so it is possible to analyse and compare more complex solutions with the proposed reference.
