Description: 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. Platform: |

Description: mura检测的论文。First, a set of
real Gabor filters are applied to eliminating the global textured
backgrounds. Then, the level set method is employed for image
segmentation with a new region-based active contours model,
which is an improvement of the Chan-Vese’s model so that it more
suitable to the segmentation of Mura. Using some results from the
level set based segmentation, the defects are quantified based on
the SEMU method.-mura test papers. First, a set of real Gabor filters are applied to eliminating the global textured backgrounds.
