Abstract: An encoding method includes following operations. Neighbouring points of a current point in a point cloud to be encoded are determined, and a first parameter is calculated according to the neighbouring points. The first parameter is a difference between a maximum value and a minimum value among reconstructed values of first attributes of the neighbouring points. In response to the first parameter being less than a threshold, a prediction value of the first attribute of the current point is determined by using a preset first prediction mode. A difference between an original value of the first attribute of the current point and the prediction value is calculated as a residual value of the first attribute of the current point. The residual value subjected to quantization is encoded. Identification information of the first prediction mode is signalled, where the identification information is used for indicating a prediction mode.

Abstract: This document describes systems and techniques related to deep association for sensor fusion. For example, a model trained using deep machine learning techniques, may be used to generate an association score matrix that includes probabilities that tracks from different types of sensors are related to the same objects. This model may be trained using a convolutional recurrent neural network and include constraints not included in other training techniques. Focal loss can be used during training to compensate for imbalanced data samples and address difficult cases, and data expansion techniques can be used to increase the multi-sensor data space. Simple thresholding techniques can be applied to the association score matrix to generate an assignment matrix that indicates whether tracks from one sensor and tracks from another sensor match. In this manner, the track association process may be more accurate than current sensor fusion techniques, and vehicle safety may be increased.

Abstract: This document describes target curvature estimation considering vehicle dynamics constraints. Some vehicle dynamics models use several kinematic states to predict the paths of targets identified by an object-tracking system. Rather than rely on predetermined industry measurements as the kinematic inputs to a model, an example system instead estimates some of these states using near real-time data output from a tracking filter. This can include estimating position and velocity states, as well as curvature and centripetal acceleration states. The example system is particularly suited at accurately predicting the curvature and centripetal acceleration states, which greatly improves the accuracy of the object-tracking system, and further improves safety in avoiding a target collision.
