Patent ID: 8745110

Claim:
A method for processing digital data by estimating a number of leader vectors in a regular point network having a norm l p as being equal to an envelope, r δ,d p , of dimension d and the co-ordinates of which are lower than or equal to k, where δ is precision and k is an integer representing a maximum network value, the method comprising computer readable memory having instructions stored thereon that, when executed by a computer processor, performed the method of: determining results of a function T(x i ) for i varying between 1 and d, where the function T(x i ) provides, for at least some of the leader vectors, a result of the division of the co-ordinate x 1 raised to the power p by a delta precision factor, the result of the division being rounded to the nearest whole number; and determining an envelope, r δ,d p , by summing the results of a function T(x i ) for i varying between 1 and d, wherein the method not comprising any step of determining leader vectors.
