<p>A method for determining a contour of at least one area having a given property on a matrix surface comprising sequentially scanned cells, comprises, for each scanned cell, the following steps:•detection (E1) of the activated or deactivated state of the currently scanned cell,•determining (E2) the activated or deactivated state of three previously scanned cells, adjacent to the currently scanned cell;•choosing (E3) a tracing instruction, on the basis of the state of the currently scanned cell and the three adjacent cells;•applying (E4) the tracing instruction; and•storing (E5) data from the tracing instruction, said data defining the contour during the sequential scanning of the cells of the matrix surface. Application to a touch-sensitive sensor comprising a matrix array of cells, and system for acquiring data from an associated touch-sensitive sensor.</p> |
