Estimating depth from a single image

A non-transitory machine-readable storage medium comprising instructions that, when executed by one or more processors of a machine, cause the machine to perform operations comprising:

• accessing a query image;
• calculating a query visual descriptor from the query image;
• obtaining a reference depth descriptor that corresponds to the query visual descriptor from a database that correlates reference visual descriptors of reference images with corresponding reference depth descriptors of the reference images, each of the reference images corresponding to a different reference depth map;
• generating a query depth map that corresponds to the query image based on the obtained reference depth descriptor;
• subdividing the query image into superpixels;
• and
• modifying the created depth map by modifying an orientation of a plane represented by a superpixel among the superpixels.

A system comprising:

• one or more processors;
• and
• a memory storing instructions that, when executed by at least one processor among the one or more processors, cause the system to perform operations comprising:
• accessing a query image;
• calculating a query visual descriptor from the query image;
• obtaining a reference depth descriptor that corresponds to the query visual descriptor from a database that correlates reference visual descriptors of reference images with corresponding reference depth descriptors of the reference images, each of the reference images corresponding to a different reference depth map;
• generating a query depth map that corresponds to the query image based on the obtained reference depth descriptor;
• subdividing the query image into superpixels;
• and
• modifying the created depth map by modifying an orientation of a plane represented by a superpixel among the superpixels.
