    Abstract: An apparatus and method for efficient image optimized image stitching. For example, one embodiment of an apparatus comprises: feature search area identification circuitry/logic to narrow down a feature search area based on possible overlap between two image frames; feature detection circuitry/logic to identify a plurality of feature points in a first image frame of the two image frames; feature matching circuitry/logic to map one or more of the plurality of feature points from the first image frame to corresponding feature points in the right image frame; image frame stitching and blending circuitry/logic to stitch the first image frame and second image frame based on the mapping of the feature points between the two image frames and to blend a portion of the first image frame with a portion of the second image frame.

    Abstract: A tone-mapping technique based on bidirectional logarithm stretch enhances the luminance contrast of not only the dark areas but also the bright areas. In other words, the algorithm not only maps the dark pixels brighter but also map the bright pixels darker.
