基于FFT的伪码捕获，并且非相关累加使之工作在更低信噪比条件下。(FFT-based pseudo-code acquisition, and non-work related cumulative so that at lower SNR.)

这个代码能够比较精确地实现图像中道路区域的分割与提取。(This code addresses this question by decomposing the road detection process into two steps: the estimation of the vanishing point associated with the main (straight) part of the road, followed by the segmentation of the corresponding road area based upon the detected vanishing point. The main technical contributions of the proposed approach are a novel adaptive soft voting scheme based upon a local voting region using high-confidence voters, whose texture orientations are computed using Gabor filters, and a new vanishing-point-constrained edge detection technique for detecting road boundaries.)
