Content-based image retrieval; indexing image; SURF descriptor; local descriptor
Resumen:
Content-based image retrieval (CBIR) is a hard task which consists in
retrieving similar content from a large multimedia database. In the
literature, in order to extract descriptors from the images the CBIR
techniques use several low-level features such as color, texture, shape,
contours, among others. In the recent years, several local descriptors
based on the detection of feature points have been used to retrieve the
most similar images with different geometric and photometric
characteristics. In this paper we propose a CBIR technique that involves
the combination of a local descriptor obtained from the Speeded Up
Robust Feature (SURF) algorithm together with an effective and fast
object matching operation in order to improve the search speed and the
retrieval accuracy related to the Mexican archaeological imaging. In
order to reduce the computational complexity of the proposed method,
Quarter Common Intermediate Format (QCIF) is used previous of computing
the SURF descriptor. To measure the performance of the proposed
technique the precision and recall metrics are used. The experimental
results show the accuracy of the proposed CBIR technique applied to a
data base of Mexican culture images that are captured by several
environmental conditions and different acquisition equipment.
