Could you please tell me how to get the edge label to supervise the model while training? #2

作者你好，请问您使用的canny边缘检测算法是将saliency map 作为输入吗？我查到的canny算法基本都是彩色图片作为输入，所以如果可以的话，方便提供一份您使用的canny边缘提取的算法代码吗? 我的邮箱hongyann.cai@gmail.com

期待您的回复，万分感谢！

I am sorry that I misunderstand the question. We use the canny algorithm to get the edge map from the segmentation results of other methods. During training, we use the simple gradient to get the ground-truth edge label. The core code is followed: [gy, gx] = gradient(gt); edge = gy.gy + gx.gx; edge(edge~=0)=1; It is implemented by matlab.

You also can use the mask to produce edge maps. The link is https://blog.csdn.net/qq_19329785/article/details/100077984
