IMAGE MATCHING METHOD BASED ON CASCADED BINARY ENCODING
First Claim
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.

Abstract
This invention involves an image matching method based on the cascaded binary encoding. 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 key-points; Procedure S2, projecting the candidate subset into a high-dimensional Hamming space; Procedure S3, a “Hamming distance-memory address” hashing table is built, and the optimal matching key-point is discovered by querying this hashing table. The image matching method proposed in this invention has high processing speed and matching quality, which can be used for efficient and accurate image matching.
