DETECTING OBJECTS IN MULTIPLE IMAGES USING INTEGRAL IMAGES

Subject matter disclosed herein relates to arrangements and techniques that provide for identifying objects within an image such as the face position of a user of a portable electronic device. An application specific integrated circuit (ASIC) is configured to locate objects within images. The ASIC includes an image node configured to process an image and a search node configured to search the image for an object in the image. The ASIC also includes an ensemble node configured to confirm the presence of the object in the image. The ensemble node progressively compares, using computational engines that include accumulators, the pixel values of a template with pixel values of a region of interest in the image to create comparison result values.
