abstract = "The detection and description of locally salient
regions is one of the most widely used low-level
processes in modern computer vision systems. The
general approach relies on the detection of stable and
invariant image features that can be uniquely
characterized using compact descriptors. Many detection
and description algorithms have been proposed, most of
them derived using different assumptions or problem
models. This work presents a comparison of different
approaches towards the feature extraction problem,
namely: (1) standard computer vision techniques, (2)
automatic synthesis techniques based on genetic
programming (GP), and (3) a new local descriptor based
on composite correlation filtering, proposed for the
first time in this paper. The considered methods are
evaluated on a difficult real-world problem,
vision-based simultaneous localization and mapping
(SLAM). Using three experimental scenarios, results
indicate that the GP-based methods and the correlation
filtering techniques outperform widely used computer
vision algorithms such as the Harris and Shi-Tomasi
detectors and the Speeded Up Robust Features
descriptor.",
