Which Is Which? Evaluation of Local Descriptors for Image Matching in Real-World Scenarios

Abstract: Matching with local image descriptors is a fundamental task in many computer vision applications. This paper describes the WISW contest held within the framework of the CAIP 2019 conference, aimed at benchmarking recent descriptors in challenging planar and non-planar real image matching scenarios. According to the contest results, the descriptors submitted to the competition, most of which based on deep learning, perform significantly better than the current state-of-the-art in image matching. Nonetheless, th… Show more

“…Heinly [42] and Oxford [13] datasets are other benchmarks which evaluate the descriptor performance under changes in viewpoint, scale, illumination, blur, rotation and compression. WISW benchmark [28] includes 5 sequences with changes in viewpoint. The features were assessed by mean average precision (mAP).…”

“…As the Hamming distance H between two of these unpacked vectors is the same as the L 1 distance between the original vectors, this representation"trick" can save matching time on all hardware configurations where H is faster than L 1 to compute. Table 1 reports on image matching results obtained with the proposed quantization scheme with planar scenes from the WISW [10] and Oxford [44] datasets (19 sequences in all, 15 from WISW and 8 from Oxford, 4 sequences being in common between the datasets. Each sequence contains 6 images, the first of which is used as reference, for a total of 19 × (6 − 1) = 95 image pairs) which include viewpoint changes, the most challenging sources of image distortion, also in combinations with other relevant image transformations, such as illumination changes.…”

“…In the following, a new and general benchmark for non-planar scenes is introduced, that extends and refines the one proposed in [11] and employed in a recent descriptor evaluation [10]. This benchmark is aimed at evaluating descriptor behavior in real-world scenes, thus providing a deep insight into descriptor characteristics, while compensating for the limitations of both the planar and the application-based benchmarks.…”
