چکیده

Local feature descriptors are widely used in many computer vision applications. Over the past couple of decades, several local feature descriptors have been proposed which are robust to challenging conditions. Since they show different characteristics in different environment, it is necessary to evaluate their performance in an intensive and consistent manner. However, there has been no relevant work that addresses this problem, especially for the affine invariant region detectors which are popularly used in object recognition and classification. In this paper, we present a useful and rigorous performance evaluation of local descriptors for affine invariant region detector, in which MSER (maximally stable extremal regions) detector is employed. We intensively evaluate local patch based descriptors as well as binary descriptors, including SIFT (scale invariant feature transform), SURF (speeded up robust features), BRIEF (binary robust independent elementary features), FREAK (fast retina keypoint), Shape descriptor, and LIOP (local intensity order pattern). Intensive evaluation on standard dataset shows that LIOP outperforms the other descriptors in terms of precision and recall metric.

Maximally Stable Local Description for Scale Selection

Scale and affine-invariant local features have shown excellent performance in image matching, object and texture recognition. This paper optimizes keypoint detection to achieve stable local descriptors, and therefore, an improved image representation. The technique performs scale selection based on a region descriptor, here SIFT, and chooses regions for which this descriptor is maximally stable...

Multiscale Keypoint Analysis based on Complex Wavelets

We describe a new multiscale keypoint detector and a set of local visual descriptors, both based on the efficient Dual-Tree Complex Wavelet Transform. The detector has properties and performance similar to multiscale Förstner-Harris detectors. The descriptor provides efficient rotation-invariant matching. We evaluate the method, comparing it to a previous wavelet based approach and to several c...

An Experimental Comparison of Image Feature Detectors and Descriptors applied to Grid Map Matching

Applying computer vision feature detectors and descriptors to occupancy grids has important practical applications for the problem of grid map matching in mobile robot localization and mapping, although this approach has received little attention by the community. This review presents a thorough performance evaluation for several combinations of detectors (Harris, KLT, SIFT and SURF) and descri...

Performance Evaluation of Point Matching Methods in Video Sequences with Abrupt Motions

In this paper, we compare the performance of matching algorithms in terms of efficiency, robustness, and computation time. Our evaluation uses as criterion, for efficiency and robustness, number of inliers and is carried out for different video sequences with abrupt motions (translation, rotation, combined). We compare SIFT, SURF, cross-correlation with Harris detector, and cross-correlation wi...

Improving Performances of BoW-based Image Retrieval by Using Contextual Keypoint Descriptors

The paper reports an improved method of content-based image retrieval using a well-known method of bag-of words (BoW). Words built over descriptors of popular affine-invariant keypoint detectors (Harris-Affine and Hessian-Affine are exemplary choices) are used. What is novel, however, is the number of descriptors (i.e. the number of words) representing individual keypoints. Instead of SIFT (or ...
