Abstract: Disclosed herein are systems, methods, and computer program products for operating a lidar system (LS). The methods comprise: receiving result values (RVs) from photodetectors (the RVs based on operations performed by each photodetector to facilitate measurements associated with a light signal reflected off an object external to LS); combining different sets of RVs to generate super pixels; using super pixels to obtain spatiotemporal coherence metrics; selecting a subset of light pulses or a group of RVs based on the spatiotemporal coherence metrics; and detecting a distance between LS and object based on the selected subset of light pulses or the selected group of RVs. The methods enable variable resolution imaging systems in which the resolution of the pixel can be configured to automatically integrate a variable number of spatial and temporal measurements that belong to the same object to improve detection quality rather than using a fixed number of measurements.
