Saliency based beam-forming for object detection

A scanning device for scanning, comprising:

• means for performing a first scan over a target region to obtain a plurality of first scan samples at a plurality of locations within the target region;
• means for generating a saliency map of the target region based on signal intensities of the plurality of first scan samples;
• means for determining a salient region within the target region based on the saliency map;
• and
• means for performing at least one second scan over the salient region to obtain at least one second scan sample in the salient region, wherein the at least one second scan is performed using beamforming to digitally steer a direction of the at least one second scan over the salient region.

A scanning device for scanning, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• perform a first scan over a target region to obtain a plurality of first scan samples at a plurality of locations within the target region;
• generate a saliency map of the target region based on signal intensities of the plurality of first scan samples;
• determine a salient region within the target region based on the saliency map;
• and
• perform at least one second scan over the salient region to obtain at least one second scan sample in the salient region, wherein the at least one second scan is performed using beamforming to digitally steer a direction of the at least one second scan over the salient region.

A non-transitory computer-readable medium storing computer executable code for a scanning device for scanning, comprising code to:

• perform a first scan over a target region to obtain a plurality of first scan samples at a plurality of locations within the target region;
• generate a saliency map of the target region based on signal intensities of the plurality of first scan samples;
• determine a salient region within the target region based on the saliency map;
• and
• perform at least one second scan over the salient region to obtain at least one second scan sample in the salient region, wherein the at least one second scan is performed using beamforming to digitally steer a direction of the at least one second scan over the salient region.
