A Binary Descriptor Structured on More Spatial Information
Hui Guobao, Dongbo Li · 2013
Conventional binary descriptor only uses limited spatial information from original image patch, such as BRIEF, which will result in limited discriminative power. We settle this problem through further excavating feature information and propose a binary descriptor encoding not only intensity comparison information but also intensity order information. Results based on experiments of performance evaluation have shown that the proposed binary descriptor outperforms other binary descriptors under rotation and scale changes.
