Strategies for noise collection? How are max_var and min_mean set? Is there any principle? #12
Comments
Have the same troubles. Looking forward the author's answer |

I cannot collect any noise patchs from face data, have you solved it? @yanghedada |
The author's noise is a flat area noise. @JingzheLyp |
@JingzheLyp me too, have you solve the problem? |
@yanghedada I did not find the noise generation code. I think the noise_collect.py just cuts the noise patch but not collects the noise. Could you please tell me where is the noise collection function? Thanks. |
Depending on your data, I would try to collect noise patches without the condition of minimum patch mean. This enforces only bright flat patches (e.g. empty sky) which may not exist in your data. You can try and play with the different thresholds and see if patches are collected successfully. It is important to visualize the resulting patches (normalize to [0,255]) and make sure that they contain only noise and not content. Otherwise, the model will learn to erase the injected content. |
How to select the threshold for extracting noise from uneven areas?I don't understand the selection trigger condition of this threshold. |
Hi
hi, how are max_var and min_mean set in the noise collection method? Do you have any experience and skills? When I collected it myself, I found that most of the noise pictures are white environment pictures. Is it because the sky pictures have more obvious noise? For face data max_var = 20, min_mean = 50 is appropriate?
thanks for your sharing! ! !
