Claim Text:
1. A method of classification of an image including determining a local binary pattern in the image, comprising: selecting an orientation; for each pixel in the image, determining a binary decision for each such pixel relative to one neighboring pixel of the orientation, wherein determining the binary decision comprises: loading a plurality of center pixel data from a multi-bank memory into a vector processor across a plurality of lanes; loading a plurality of pixel data for neighboring pixels from the multi-bank memory into the vector processor across the plurality of lanes; performing a pack instruction in which each center pixel is compared to the corresponding orientation pixel data and binary results of the comparisons are written to an output register; after determining the binary decisions for the pixels of the image, selecting a new orientation; repeating the determination of the binary decision for each pixel in the image relative to one neighboring pixel of the newly selected orientation; and classifying the image corresponding to the determined local binary pattern.
