Extract information directly from images？

[wdj1995]

Thank you very much for your research. I have downloaded your data and code, and try to run and debug it. I would like to ask how this project can extract lines, junctions, depth and vanishing points from only one image. I would appreciate it and hope you can give me some suggestions.

Your question is too general. I would suggest starting from reading the paper and getting you familiar with the literature.

非常非常感谢您的回复，我的问题简单来说就是，我尝试只用我的png照片就获取边缘信息、连接点等各类信息。但是呢，我看数据集SU3和预训练数据集pretrained中，全部都是已经提供了照片的各类边缘、连接点、消失点、深度信息的npz文件了，假如我想利用您的项目仅仅使用一张照片就重建建筑物的曼哈顿线框，我该怎么做呢？希望您能简单说一下您的建议！！！非常感谢

The shapeunity is a supervised learning algorithm, so it needs labels for training. During inference, the information you mentioned above (lines, etc) is not required.

If your goal is to use the algorithms without training data, that you can only refer to the traditional algorithms like LSD and J-LINKAGE. Of course, that would be much harder.
