【摘要】 为了更加清晰准确地检测出彩色图像的边缘,提出了一种改进的Canny边缘检测方法,将彩色图像从RGB颜色空间转换到颜色均匀的L*a*b*空间,用色差Canny算子来计算彩色图像的色差和色差方向.彩色直线和曲线道路图像的边缘检测效果证明了改进算子的有效性.更多还原

【Abstract】 In order to detect the edge of color image more clearly and accurately, this paper presents an improved Canny edge detection method, that Canny operator based on color difference is used to calculate the color difference and color directions of color image by converting color image from RGB color space to theL*a*b*space of uniform color. The edge detection results of line and curve road color image prove the effectiveness of the improved operator.更多还原
