DEVICE FOR OBJECT DETECTION IN AN IMAGE, AND METHOD THEREOF

摘要

The present invention relates to a device and a method for detecting an object in a digital image (42) using a field programmable gate array (74). The proposed device includes an image acquisition interface (78) adapted for receiving pixel values of an input digital image (42) from an image sensor (72), and writing the received pixel values on to a plurality of addressable image buffers (88,90,92) contained. The proposed device further includes feature extraction means (80) adapted for reading the pixel values from at least one addressable image buffer, out of the plurality of addressable image buffers (88,90,92), and extracting a plurality of feature vectors for a window (40) within the digital image (42). A decision logic (98) is provided that is adapted for performing an arithmetic operation on the extracted feature vectors and corresponding support vectors stored in an internal memory means (89), and deciding the presence of an object in the window (40) based upon a result of the arithmetic operation.
