Object detection using direction polarity invariant corner parameterization

A computing system comprising:

• one or more memories;
• and
• processing circuitry implemented in circuitry, coupled to the one or more memories, and configured to:
• estimate, for an object in an image, positions of one or more corners that correspond to one or more corner categories that are invariant to a direction polarity of the object;
• determine an estimated reference point of a bounding box that bounds the object based on the positions of the one or more corners of the object and the one or more corner categories that correspond to the one or more corners;
• generate the bounding box based on the estimated reference point of the bounding box;
• and
• output an indication of the bounding box.

A computer-readable storage medium storing instructions thereon that when executed cause processing circuitry to:

• estimate, for an object in an image, positions of one or more corners that correspond to one or more corner categories that are invariant to a direction polarity of the object;
• determine an estimated reference point of a bounding box that bounds the object based on the positions of the one or more corners of the object and the one or more corner categories that correspond to the one or more corners;
• generate the bounding box based on the estimated reference point of the bounding box;
• and
• output an indication of the bounding box.
