[Question] Content mask format #62

Open mfxuus opened 5 years ago

mfxuus commented 5 years ago

I've been exploring INetwork.py, and the regular neural style transfer works well, but if I add the --content_mask option it results in the following error:

The full command is

and if I remove the last part (--content_mask), everything runs fine. It is likely something is wrong with my mask image, but I've tried jpg / png / bmp (all using Windows paint / 3d paint). Just wondering if you have any idea what could be the issue? Thanks in advance!

titu1994 commented 5 years ago

PIL is having issues loading your mask image. Try loading the image in a seperate script or the Python interpreter and see if it works. Likely it is an issue with the mask.

mfxuus commented 5 years ago

Hmmm, so it seems that in INetwork.py, line 268 mask = imread(mask_path, mode="L") # Grayscale mask load reads the image into an array, and then on the next line, mask = imresize(mask, (width, height)).astype('float32'), which in turn goes to 

if type(img) != Image:
        img = Image.fromarray(img, mode='RGB')

in utils.py, the error is called when forced to use mode RGB on the balck/white image (which has shape of (W, H) and no RGB dimensions). However, if I change this line to allow other mode, some other errors appear later in the program. Therefore the initial question of what kind of image should I pass in as a mask? If it helps, I can try to reproduce the "errors later in the program" and paste it here later today.

titu1994 commented 5 years ago

The mask image must be a binary image, with pixel values either 0 or 1. It can be saved as a png preferably.

Could you also paste the errors that occur. I think I need the refactor my utils.py script to account for masking in mode L

mfxuus commented 5 years ago

Sure. So if I change utils.py at ~line 33 into:

if type(img) != Image:
    try:
        img = Image.fromarray(img, mode='RGB')
    except:
        img = Image.fromarray(img)

I get the following:
