WebbIntroduction. Multi-object smoothing shares a lot of common features with the multi-object tracking problem. Like a multi-object tracking algorithm, the goal of a multi-object smoothing algorithm is to estimate the number of objects and their trajectories in the presence of missed detections, false alarms, and noisy sensor observations. WebbThe following examples show how to use org.nd4j.linalg.factory.nd4j#randn() .
