基于Canny算子的红外图像边缘检测研究

在红外图像处理中,提出了尺度相乘的Canny边缘检测器,定义了尺度相乘函数,该函数是两个尺度检测滤波器响应的乘积.通过确定尺度相乘后的梯度图像,采用非最大值抑制方法得到边缘图像.实验结果表明,该算子提高了传统Canny检测算子的性能,具有良好的检测精度,在定位和噪声抑制两方面得到了较好的折中.

Study of Infrared Image Edge Detection Based on Canny Operator

A Canny edge detector by scale multiplication is proposed in infrared image processing,a scale multiplication function is defined as the product of the responses of the detection filter at two scales.Using the non-maximal suppression method,the edge map is obtained by confirming the gradient map of the scale multiplication.It can be demonstrated that the performance of the traditional Canny detection operator is improved through the experiment and the detection accuracy is better.A good trade-off effect can be attained at the localization and the noise suppression.
