Some questions about making detector dataset

[slimhappy]

Hello, tancik ! I am keen on your outstanding work. But when I was traing a detector for distiguishing the encoded images from complex background (not totally white), I have some trouble about making dataset. Here is my questions:

1. Are the encoded images placing on totally white background in the traing dataset for detector?

2. If the encoded image's size is small (maybe 1/100 of an A4 paper), how can I make a training dataset to get great precision ?

   Finally, I have written a documentation to guide chinese novices to build an environment and turn your code from tensorflow 1.x to tensorflow 2.x. I hope you will like it and it can help more githubers to run your work.

Hello, I received a reply from the author as follows:

 

 

 

''  I don't remember exactly how large the transformations were, I just chose a value that matched what I wanted to recover in the real-world. In fact the detector is just learning how to pick out an image on another image. I found that training it on just square images (not stegastamped) pasted on a large image worked just as well. Because of the error detection when decoding the stegastamp it is fine if the detector isn't perfect. There is a lot that could be explored to make the detector better including end-to-end training. I am excited to see if someone pursues this direction. ''
