Japanese Patent JP3060579

Kind Code:

B2

Abstract:

PURPOSE:To easily obtain a motion vector for matching of two functions even in the case of the long motion vector. CONSTITUTION:A linear differential function related to a position vector of a function f1() and a function f2() is obtained, and the inner product between an average function of linear differential functions of functions f1 and f2 and an experimental motion vector is added to the result obtained by subtracting the function f1 from the function f2 to obtain a matching error, and a collateral condition formula is added to the square of the absolute value of this matching error to obtain an evaluation function, and the value of the experimental motion vector is so determined that the value of the evaluation function is minimum.
