1. A computer implemented method for using computer vision to guide processing of receive radio frequency (RF) responses of radio detection and ranging (RADAR) sensors of a vehicle in a driving environment, the computer implemented method comprising:
receiving, with one or more receivers of RADAR sensors, environment receive RF responses;
receiving region of interest (ROI) information including segments of a tentative set of ROIs with free space area boundaries from an image processor of an image processing chain for the computer vision;
dynamically determining a number of polyphase filters based on a number of ROIs having dynamic scenes that are provided by the image processing chain; and
adjusting parameters of the polyphase filters of a RADAR processing chain based on the ROI information.
