Feature detection, sorting, and tracking in images using a circular buffer

Abstract

An example apparatus for tracking features in image data includes an image data receiver to receive initial image data corresponding to an image from a camera and store the image data a circular buffer. The apparatus also includes a feature detector to detect features in the image data. The apparatus further includes a feature sorter to sort the detected features to generate sorted feature points. The apparatus includes a feature tracker to track the sorted feature points in subsequent image data corresponding to the image received at the image data receiver. The subsequent image data is to replace the initial image data in the circular buffer.

What is claimed is: 
     
         1 . An apparatus for tracking features in image data, comprising:
 an image data receiver to receive initial image data corresponding to an image from a camera and store the image data a circular buffer;   a feature detector to detect features in the image data;   a feature sorter to sort the detected features to generate sorted feature points; and   a feature tracker to track the sorted feature points in subsequent image data corresponding to the image received at the image data receiver.
