DEVICE FOR SELECTING AND DESCRIBING POINTS OF INTERET IN A SEQUENCE OF IMAGES, FOR EXAMPLE FOR THE PAIRING OF POINTS OF INTERET

摘要

Calculation device (100) for the selection and the description of points of interest in at least one image decomposed into a plurality of strips, the said device (100) comprising: ∙ a first module (SI PI) for selecting and indexing points of interest from among a set of points of interest detected in the image, the said first module (SI PI) being configured to select, in each strip, at most a fixed number P of candidate points of interest, and associate them with a unique index, ∙ a second management module (GIPI) for calculating descriptors for the candidate points of interest, ∙ the first module (SI PI) being configured to transmit to the second module (GIPI) the candidate points of interest and their index as soon as K lines of a strip have finished being processed, with K an integer number greater than or equal to 1 and strictly less than the number of lines per strip.
