Abstract: 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.

Abstract: 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.

Abstract translation: 用于通过小波变换将图像分解为至少三个级别的装置包括执行第一级分解的第一单元和通过执行一系列处理任务来执行较高级别的分解的第二单元。 通过使用一系列行来及时排序任务，当与当前正在执行的处理任务相关联的分解级别相对于先前执行的处理任务相关联的分解级别改变时，用于配置第二单元的路由单元。 处理任务被排序，使得任何给定行仅与一个级别的分解相关联。
