摘要
选用定位准确的Canny算子,提出一种基于Canny理论的彩色图像边缘检测方法。彩色图像的梯度幅值用其r、g、b分量的梯度幅值之和计算,方向角用r、g、b分量的y方向梯度幅值之和与r、g、b分量的x方向梯度幅值之和的比来确定。从检测结果中可以看出,基于Can-ny理论的彩色图像边缘检测能检测出更多的边缘细节。这说明,用该方法检测彩色图像的边缘是有效的。
Based on Canny operator, This paper have proposed a edge detection method of colored picture based on Canny theory, as the operator can make a reservation accurately. The gradient amplitude of the colored picture are calculated by using the sum of the gradient amplitude of component r, g, b, and direction angle is confirmed by the ratio between the sum of the y direction gradient amplitude of component r, g, b and the sum of the gradient amplitude of x direction of component r, g, b. The results show that the colored picture edges detected by Canny operator have more edge details and thus verify the validation of the method to detect the edge of the colored picture.
