Abstract: Certain embodiments of the present invention provide systems and methods for multimedia messaging. Certain embodiments include authorizing user access for multimedia content messaging, selecting one or more recipients, providing multimedia content, creating a message addressed to the one or more recipients including the multimedia content, specifying a message mode for the message, and allowing review of the message by the one or more recipients based at least in part on the mode. Provided content may include recording multimedia content, purchasing multimedia content, and/or selecting previously-created multimedia content, for example. In certain embodiments, one or more recipients may be added to or invited to join a messaging group. In certain embodiments, a message appearance may be altered based the multimedia content, the mode and/or the one or more recipients, for example. In certain embodiments, a multimedia greeting associated with a user may be created.

Abstract: Methods and apparatus for rendering images are presented. The method includes the step of segmenting at least one reference image in a reference image space into a plurality of tiles, each tile defined by a corresponding set of image samples. The connectivity of each of the samples is determined based on the relative curvature of a surface of the corresponding tile at the sample coordinates. Color and depth information between adjacent, connected samples is bi-linearly interpolated to form a corresponding set of sub-samples. The set of sub-samples are warped from the reference image space to a destination image space. A final pixel color for each of a plurality of groups of sub-samples in the destination image space is computed as a weighted average of the color information of the sub-samples for each respective group. The final pixel colors are combined to render a final image in the destination image space from the at least one reference image.
