A method, apparatus and computer program product are provided for estimating and verifying translation motion and/or a scaling factor between face regions in respective frames during face tracking. A method determines translation motion between face regions in two successive frames based upon integral gradient projections of a face region in a first frame and a corresponding window in a second frame. The method also verifies the translation motion between the first and second frames utilizing integral gradient projections. A method also determines a transfer function relating integral projection curves of a face region in a first frame that has a predefined position and a predetermined size and a co-located window of same size in a second frame, determines a scaling factor based upon the transfer function and then verifies the scaling factor utilizing integral gradient projections.

A method, apparatus and computer program product are provided for determining spatial location for one or more facial features. A method computes features for an initial frame. The computed features of the initial frame generate a feature image. A method also determines whether a translation is verified between the initial frame and an intermediate frame, wherein a translation is verified in an instance in which a distance used to verify the translation between the initial frame and the intermediate frame is within a predetermined threshold level. A method also includes a face search, using a portion of the feature image, for one or more facial features, wherein the portion of the feature image searched is a fraction of the total number of frames analyzed in a feature computation cycle. A method also determines a spatial location for the one or more facial features detected in the intermediate frame.

An apparatus for determining a pose(s) of an object(s) may include a processor and memory storing executable computer code causing the apparatus to at least perform operations including receiving a detected image of at least one face and analyzing the image of the at least one face based on data of at least one model identifying one or more poses. The poses may be related in part to at least one of a position or an orientation of respective faces. The computer program code may further cause the apparatus to determine that the face corresponds to one of the poses based in part on one or more items of data of the image passing criteria identified by the model as corresponding to the pose. Corresponding methods and computer program products are also provided.

A red-eye detection and correction method comprises computing a first difference image based on a difference between red pixel intensity and green pixel intensity of a set of pixels (702). The set of pixels are associated with a first eye region of an image. The method further comprises processing the first difference image for computing at least one gradient and at least one projection associated with the at least one gradient (704). Furthermore, the method comprises determining at least one central point based on the at least one projection (706); and thereafter computing the first eye color defect region based on the at least one central point and a plurality of red pixels of the set of pixels (708). The method also comprises mapping an eye color defect location information computed from a low resolution image to be applicable on the original high resolution image, thereby avoiding recomputation.
