First Claim
1. An apparatus comprising:
- an image processor comprising first and second hardware accelerators;
the image processor being configured to implement a classifier utilizing the first and second hardware accelerators;
wherein at least one of the first and second hardware accelerators is configured to generate an integral image based on a given input image; and

Abstract
An image processor comprises first and second hardware accelerators and is configured to implement a classifier. The classifier in some embodiments comprises a cascaded classifier having a plurality of stages with each such stage implementing a plurality of decision trees. At least one of the first and second hardware accelerators of the image processor is configured to generate an integral image based on a given input image, and the second hardware accelerator is configured to process image patches of the integral image through one or more of a plurality of decision trees of the classifier implemented by the image processor. By way of example, the first and second hardware accelerators illustratively comprise respective front-end and back-end accelerators of the image processor, and an integral image calculator configured to generate the integral image based on the given input image is implemented in one of the front-end accelerator and the back-end accelerator.
