Resolution for output images

[ghost]

Marcus, Thanks for sharing your nice augmentation tool. I really like it.

I am wondering how to keep output images to be the same resolution as input images after finishing augmentation. I do see that there is a loss of resolution for augmented images. Please let me know where I could make a change for the code in order to keep the same resolutions. Thank you for your advice!

Best regards,
Peter

Hi Peter,
I assume you mean the quality of the images rather than the dimensions of the images? In that case, saving as PNG may help, but each operation is going to introduce some kinds of artefacts due to resampling and so on.

Right now, users do not have the ability to change the resampling method (most operations default to bicubic) but I will add the ability to specify this in a future version, which I plan to release soon.

Of course you can add a resize operation as the final operation to a pipeline using the resize(probability, width, height) method with probability set to 1, if you do mean the dimensions of the images.
