Abstract:
1. A stereo image correlation method, comprising: receiving a multi-bit descriptor of an image point of a first image; applying a first hash function to a sub-set of bits from the descriptor of the image point of the first image to provide a first hash function value; storing a coordinate of the image point of the first image into a location of a first hash table, the location identified by the first hash function value; receiving a multi-bit descriptor of an image point of a second image, the first and second images forming a stereo image pair; applying the first hash function to the sub-set of bits from the descriptor of the image point of the second image to provide a second hash function value; and querying the first hash table using the second hash function value to identify a coordinate of an image point of the first image that may be a match to the image point of the second image.
