Abstract
Systems and methods are provided for detecting objects of an object class, such as faces, in an image sensor. In some embodiments, the image sensor can include a detector with an image buffer. The image buffer can store image data in raster order. The detector can read the data out in Z order to perform object detection. The image data can then compute feature responses using the Z-ordered image data and determine whether any objects of the object class are present based on the feature responses. In some embodiments, the detector can downscale the image data while the object detection is performed and use the downscaled image data to continue the detection process. In some embodiments, the image data can perform detection even if the image is rotated.
