Depth image data structure for storing image depth information

A method for processing image depth information, comprising:

• obtaining a depth image data structure representative of depth information for an image comprising a plurality of pixels corresponding to a plurality of coordinates in the image, wherein the depth image data structure comprises a plurality of depth values associated with a subset of pixels of the plurality of pixels, wherein the depth image data structure comprises:
• a plurality of tracks, each track of the plurality of tracks representing a respective interval along a first dimension of the image, wherein:
• the subset of pixels are located at coordinates of the image represented by one or more tracks of the plurality of tracks;
• and
• each track of the one or more tracks includes respective depth information for each respective pixel of respective one or more pixels of the subset of pixels located at respective one or more coordinates of the image represented by the track, wherein the respective depth information for each respective pixel includes a respective depth value for the respective pixel and a portion of a respective coordinate of the respective pixel in the image;
• and
• processing the depth image data structure to detect one or more objects in the image.

One or more non-transitory computer-readable media comprising executable instructions that, when executed by one or more processors of an apparatus, cause the apparatus to perform operations comprising:

• obtaining a depth image data structure representative of depth information for an image comprising a plurality of pixels corresponding to a plurality of coordinates in the image, wherein the depth image data structure comprises a plurality of depth values associated with a subset of pixels of the plurality of pixels, wherein the depth image data structure comprises:
• a plurality of tracks, each track of the plurality of tracks representing a respective interval along a first dimension of the image, wherein:
• the subset of pixels are located at coordinates of the image represented by one or more tracks of the plurality of tracks;
• and
• each track of the one or more tracks includes respective depth information for each respective pixel of respective one or more pixels of the subset of pixels located at respective one or more coordinates of the image represented by the track, wherein the respective depth information for each respective pixel includes a respective depth value for the respective pixel and a portion of a respective coordinate of the respective pixel in the image;
• and
• processing the depth image data structure to detect one or more objects in the image.
