  • Efficient scale-space extraction and description of interest points
    Patent number: 8798377
    Abstract: Method, system and computer program for efficiently extracting and describing scale-space interest points. It is designed towards low overall computational complexity. On one hand, the data acquired during extraction in the description phase is intensively re-used. On the other hand, an algorithmic optimization of the description that dramatically speeds up the process, is proposed. First, the image is filtered with triangle kernel at different scales. The triangle filtered images are reused for extraction of the keypoints dominant orientation and the computation of the DAISY-like descriptor.
    Type: Grant

    Date of Patent: August 5, 2014
    Assignee: Telefonica, S.A.
