CMOS image sensor architecture for focal plane early vision processing
This paper presents a pixel architecture that aims at validating the idea that with a small change in the pixel it is possible to perform important image processing computations at the focal-plane without significantly affecting the fill factor. An overview of two algorithms that may benefit from this new pixel architecture is given, namely the SIFT for object recognition and the Viola-Jones for face detection. A brief discussion of the limitations of the computations performed inside the pixel matrix and the future work is also presented.
