Auto-exclusion zone for contour-based object detection

A method, comprising:

• during an initial time interval:
• receiving one or more first top-view images generated by a first sensor, the first sensor configured to generate top-view images of at least a first portion of a space;
• detecting one or more first contours in the one or more first top-view images;
• determining first pixel coordinates corresponding to the detected first contours, wherein the first pixel coordinates correspond to regions of the top-view images generated by the first sensor to exclude during object tracking;
• and during a subsequent time interval after the initial time interval:
• receiving a second top-view image generated by the first sensor;
• detecting a second contour in the first top-view image;
• determining second pixel coordinates corresponding to the detected second contour;
• determining whether at least a threshold percentage of the second pixel coordinates overlap with the first pixel coordinates;
• in response to determining that at least the threshold percentage of the second pixel coordinates overlap with the first pixel coordinates, not determining a first pixel position for tracking the second contour;
• and
• in response to determining that at least the threshold percentage of the second pixel coordinates do not overlap with the first pixel coordinates, determining the first pixel position for tracking the second contour.

A device communicatively coupled to a first sensor, the first sensor configured to generate top-view images of at least a first portion of a space, the device configured to:

• during an initial time interval:
• receive one or more first top-view images generated by the first sensor;
• detect one or more first contours in the one or more first top-view images;
• determine first pixel coordinates corresponding to the detected first contours, wherein the first pixel coordinates correspond to regions of the top-view images generated by the first sensor to exclude during object tracking;
• and during a subsequent time interval after the initial time interval:
• receive a second top-view image generated by the first sensor;
• detect a second contour in the first top-view image;
• determine second pixel coordinates corresponding to the detected second contour;
• determine whether at least a threshold percentage of the second pixel coordinates overlap with the first pixel coordinates;
• in response to determining that at least the threshold percentage of the second pixel coordinates overlap with the first pixel coordinates, do not determine a first pixel position for tracking the second contour;
• and
• in response to determining that at least the threshold percentage of the second pixel coordinates do not overlap with the first pixel coordinates, determine the first pixel position for tracking the second contour.
