Patent Images

1. An image matching method based on cascaded binary encoding, characterized in that the stated method includes:

  • Procedure S1;

    Using the hashing look-up with multiple hashing tables to coarsely filter candidate key-points in the image to produce a candidate subset of the candidate key-points;

    Procedure S2;

    Projecting the candidate subset of the candidate key-points into a high-dimensional Hamming space;

    Procedure S3;

    Building a “

    Hamming distance-memory address”

    hashing table, and obtaining the optimal matching key-point by querying this hashing table.
