Classification: CPC G | IPC G

Claim 0:
1. A system for ego vehicle speed estimation, comprising
a car-mounted monocular camera for capturing a sequence of video frames of an outdoor scene from a moving car, where the outdoor scene includes a road, as a camera channel;
processing circuitry configured with
a single-shot network, and
a neural network time series model,
wherein the single-shot network segments features of the road in the video frame sequence and generates a masked-attention map for the segmented road features;
a concatenation operation that concatenates the masked-attention map as an additional channel to the camera channel to generate a masked-attention input;
wherein the neural network time series model receives the masked-attention input and generates an estimated speed of the ego vehicle based on displacement of the segmented road features in the video sequences; and

output circuitry to output a signal indicating the estimated speed.
