Depth accuracy is one of the most important characteristics for sensors used in distance estimation. Stereo-vision systems employ sub-pixel interpolation to achieve such accuracy. Literature in this domain is usually dedicated to simple window based stereo solutions. There are currently several new stereo algorithms developed to counter pixel level errors, but they neglect sub-pixel results. We propose...
This paper describes a new alternative procedure to improve the invariance to illumination changes on the image feature extraction provided by Harris corner detectors, using the local image moments information. Another alternative is presented for the matching process, which is enhanced adding local SURF descriptors. These both techniques are joined to give us a new promising visual guidance tool...
This paper presents a new real time lane detection and tracking system which succeeds in sharp curved roads. The Warp Perspective Mapping (WPM) method was used to change the video image perspective to top view. A two dimensional Gabor filter and vertical pixel density calculation method was used to find initial lane regions. Second derivative approach of Composite Bezier spline fitting method calculates...
