Hi @dinusha94 , thank you so much for your attention to our project. It sounds like you may have input the wrong image path for target or exemplar folders.
target'',
exemplar'', and ``mask'' folders by yourself, and then input these three folder paths.
For example, you can create target1, exemplar1, and mask1 folders and put your images into corresponding folders.
and also change the command by replacing your new paths.Let me know if it works or not. Thanks!
Thaks for the response.
I did as you mentioned, but still the I got the same results. following is my python command and its response

Hi @dinusha94
I found the problem here, it is because I hard-coded the three paths. Could you download the exemplar_style_mixing.py again and try again? Thanks!
Hi @LonglongaaaGo
Thanks a lot, it works now. I have two questions though.
I am trying to use a single example image which is generated from Open AI Dalle with a ground truth image
1 . regarding face alignment before style mixing. Is it a must to do the face alignment before using it for every image (or do we need to do it for badly aligned faces)
Hi @dinusha94 , Thanks for the good questions. First, face alignment is needed, because the training data (FFHQ) are from aligned images, and the capacity of the GAN-based model is somehow limited. If we try to use poorly aligned faces, the face will be collapsed. Second, we, of course, can use only one exemplar image for inpainting/editing. Could you please download exemplar_style_mixing.py again? You can activate the code at line 212 and comment out the code at line 213.
After running, you would get diverse completed images guided by only one exemplar image.
Thanks!
Hi @dinusha94 , oh, I realized that you could directly use guided_recovery.py. Please take a look at the README for more details. Thanks!
Hi @LonglongaaaGo
Thanks for all the help. I would like to know you're Idea about the results I got with the following images. (I ran the guided_recovery.py script)
My final goal was to change the hairstyle and color of the ground truth image using the exemplar image. But the results I got are a little bit far from what I expected. I would like to know if I would be able to improve these by training with a new dataset.
Hi @dinusha94 , Yes, It is an interesting idea. I think now the pre-trained model could not achieve your goals for several reasons. First, our model is an inpainting method, which is trained to seamlessly fill the masked regions using exemplar facial attributes. So this model has to consider the context of the masked regions, but also think about how to perform reasoning to generate appropriate attributes. Thus, you will find that the color of the hair has to consider the background or context of hair colors. You can try to remove all the hair and fill it again. Second, to guide the hair structure, a sketch-based model is needed. You can follow our paper, to add one channel of image sketch to guide the structure of hair (train a new model). Third, to manipulate the color, you may also include a color channel to control the color generation (train a new model). Recently, our team has been working on that. One paper for multimodal guided image editing is under review. So, if you are not in a hurry, we may release a novel multimodal facial editing method after a couple of months.
Thanks!
That is great to hear. Meantime I can try to train a model with my dataset.
Is adding a channel means adding it to the mask of the training data? (i.e 3 channel mask with replacing the white area with the desired color and extra channel in the mask for sketch, is that correct). Is this the thing mentioned in the section 5.3 in you're paper.
Are there any python script in the github repo which can be used with the sketch ? Since it is shown in the Readme
Hi @dinusha94 ,
Now, we have four channels (3 for an input RGB image and 1 for an input mask). If we add extra sketch (1 channel ) and colors (3 channels), there will be 8 channels.

Hi, I am excited about your model and tried to use it with my images for style mixing. I have a ground truth image and an example image which are face aligned and 256x256. also have a mask with 256x256. when I ran the following command in colab after all the installation steps, I got the same results mentioned in the ReadME. not for my images.
command I ran is as follows:
%cd /content/EXE-GAN !python exemplar_style_mixing.py \ --psp_checkpoint_path /content/psp_ffhq_encode.pt \ --ckpt /content/EXE_GAN_model.pt \ --masked_dir /content/EXE-GAN/imgs/exe_guided_recovery/mask \ --gt_dir /content/EXE-GAN/imgs/exe_guided_recovery/target \ --exemplar_dir /content/EXE-GAN/imgs/exe_guided_recovery/exemplar \ --sample_times 2 \ --eval_dir /content/EXE-GAN/imgs/exe_guided_recovery/mixing_out
Any help on this would be highly appriciated
