Construction of fixed points of nonexpansive mappings and asymptotically nonexpansive mappings is an important subject in the theory of nonexpansive mappings and finds its applications in a number of applied areas, in particular in image recovery and signal processing (see, for example, Byrne, 2004; Podilchuk and Mammone, 1990; Sezan and Stark, 1987; Youla, 1987, 1990).
However, the sequence {Tnx}1= 0 of iterates of the mapping T at a point x 2 C may not converge even in the weak topology and since averaged iterations prevail. Mann (1953) introduced the following iterative procedure for approximating a fixed point of a nonexpansive mapping T in a Hilbert space H:
