A calculation device, for the selection and the description of points of interest in at least one image decomposed into a plurality of strips, includes a first module for selecting and indexing points of interest from among a set of points of interest detected in the image, the first module being configured to select, in each strip, at most a fixed number P of candidate points of interest, and associate a unique index with them, a second module for managing calculation of descriptors for the candidate points of interest, the first module being configured to transmit the candidate points of interest and their index to the second module immediately at the end of the processing of K lines of a strip, with K an integer number greater than or equal to 1 and strictly less than the number of lines per strip.

Device for selecting and describing points of interest in a sequence of images, for example for the pairing of points of interest

A device for decomposing images into at least three levels by wavelet transform comprises a first unit executing a first level of decomposition and a second unit executing the higher levels of decomposition by performing a sequence of processing tasks. The tasks are ordered in time by using a sequence of rows, a routing unit serving to configure the second unit when the level of decomposition associated with the processing task currently being executed changes relative to the level of decomposition associated with the processing task executed previously. The processing tasks are ordered so that any given row is associated with only one level of decomposition.

A reconfigurable computation device for image processing, the device including a neighborhood-based computation matrix, generating pairing sub-scores between pairs of pixels resulting from a first series of operations configurable via a configuration register; a flexible reduction tree, carrying out a second series of operations configurable via the configuration register, on neighborhoods of pixels configurable via the configuration register; and an analysis matrix, carrying out computations configurable via the configuration register on the results arising from the flexible reduction tree.
