Abstract

In accordance with an example embodiment a method, apparatus and computer program product are provided. The method comprises facilitating a selection of a region in a multimedia frame and performing an alignment of multimedia frames occurring periodically at a pre-defined interval in a capture order associated with a plurality of multimedia frames based on the multimedia frame comprising the selected region. The method further comprises computing region-match parameters corresponding to the selected region for the aligned multimedia frames. One or more multimedia frames are selected from among the aligned multimedia frames based on the computed region-match parameters and a multimedia frame is identified from among the selected one or more multimedia frames and multimedia frames neighbouring the one or more selected multimedia frames based on the computed region-match parameters. The multimedia frame is identified for configuring a loop sequence for an animated image.
