We present a hardware architecture for the extraction of image feature descriptors, based on a model inspired on the Human Retina. This model comes from an analysis of a recent descriptor extractor, the FREAK (Fast Retina Keypoint) method, which has shown good performance results for different Computer Vision applications. From such analysis we decide the approximations that may be made to the original...
Embedded signal-processing applications often require feature tracking to identify and track the motion of different objects (features) across a sequence of images. Common measures of similarity for real-time usage are either based on correlation, mean-squared error, or sum of absolute differences, which are not robust enough for safety-critical applications. A recent feature-tracking algorithm called...
We present an implementation of the Speeded Up Robust Features (SURF) on a Field Programmable Gate Array (FPGA). The SURF algorithm extracts salient points from image and computes descriptors of their surroundings that are invariant to scale, rotation and illumination changes. The interest point detection and feature descriptor extraction algorithm is often used as the first stage in autonomous robot...
