Method for processing an object on a platform having one or more processors and memories, and platform using same

A method, implemented on a platform, for processing an object having at least two dimensions and including a plurality of pieces of elementary information by a platform, each piece of elementary information being represented by at least one numerical value, said platform including, according to at least one circular chaining, at least one queue and N*P processors located according to a grid of N*P processors corresponding to a rectangle of N processors horizontally and P processors vertically, said method comprising:

• performing, via each processor, a sequence of specific operations on sub-objects of the object that have a number of pieces of elementary information identical to the number of processors, said specific operations including calculation of an arbitrary number of vertical and/or horizontal and/or non-separable filters on at least one piece of elementary information;
• transferring a result of at least one same specific operation of the sequence of specific operations performed by each of the processors to a processor or queue that follows according to the circular chaining;
• receiving, in said queue, at least one result of said same specific operation performed by one of the processors of the circular chaining located at a first extremity of the grid;
• and
• receiving, in another processor of the circular chaining located at a second extremity of the grid, at least one result of said same specific operation of said queue performed before by said processor of the circular chaining located at the first extremity of the grid.
