A method for recognizing image artifacts in a chronological sequence of recordings recorded by means of a lighting device and an optical sensor is disclosed. A difference movement field is obtained by removing from a movement field all movement field vectors to be expected due to inherent movement of a lighting device and an optical sensor. The movement field vectors in the difference movement field are combined into one or more objects according to at least one grouping criterion. The objects in the image are classified as plausible or as implausible pursuant to a movement plausibility test. An object classified as implausible is recognized as an image artifact.

Motion Classification Using Low-Level Detections
20230013221 · 2023-01-19 ·

Techniques and apparatuses are described that implement motion classification using low-level detections. In particular, a radar system identifies fused detections associated with an object and determines whether the fused detections indicate that the object is moving. If it is determined to be moving or moving perpendicular to the host vehicle, a current motion counter or perpendicular motion counter is incremented, respectively. A current motion flag and/or a perpendicular motion flag are set as true if the current motion counter or the perpendicular motion counter has a value greater than a threshold value, respectively. In response to setting either flag as true, the radar system increments a historical motion counter as true. The host vehicle is then operated based on the current motion flag, the perpendicular motion flag, and the historical motion counter. In this way, the radar system introduces hysteresis to improve the reliability and stability of motion classification.
