How motion imitation custom images

Hi, The cross-identity reenactment method will be provided in the next few days. You can use the code to animate your images. Yurui

Hi, @RenYurui so awesome project, congratulations to you. I have tested the cross-identity reenactment, but the result is not good about the identity preservation problem, as shown as the following:

Can you help me fix the problem?

hi @clumsynope, can you tell me how to run the cross-identity? are you using a custom image?

out.mp4 Can you help me fix the problem?

I have fixed the problem. Just replace the crop parameter with the source's crop parameter.

@RenYurui Thanks you share your greate work. I have tested the cross-identity reenactment,but not very good.

Hi, would mind share details about how to replace the crop parameter with the source's crop parameter. Thanks

In Line 33 of vox_video_dataset.py, replace the last 3 dimensions of semantics_numpy with the source's, like semantics_numpy[-3:]=source_semantics_numpy[-3:]. As for source_semantics_numpy, you can get it like how you get semantics_numpy.

你好，我按照你的提示修改并测试了一下， 感觉还是有一些问题。cross id 的时候，外貌特征也会被迁移过去。 感觉 ID 信息并没有传递过去，下面是 vox_dataset.py 中的代码，不知道大佬具体是如何修改的。 ` def transform_semantic(self, semantic, frame_index): index = self.obtain_seq_index(frame_index, semantic.shape[0]) coeff_3dmm = semantic[index,...] # id_coeff = coeff_3dmm[:,:80] #identity ex_coeff = coeff_3dmm[:,80:144] #expression # tex_coeff = coeff_3dmm[:,144:224] #texture angles = coeff_3dmm[:,224:227] #euler angles for pose # gamma = coeff_3dmm[:,227:254] #lighting translation = coeff_3dmm[:,254:257] #translation crop = coeff_3dmm[:,257:300] #crop param coeff_3dmm = np.concatenate([ex_coeff, angles, translation, crop], 1) return torch.Tensor(coeff_3dmm).permute(1,0)

`

I just modify the code in vox_video_dataset.py like this:

def load_next_video(self):
    data={}
    self.video_index += 1
    video_item = self.video_items[self.video_index]

    video_item_src = self.video_items[random.randint(0, len(self.video_items))] # random select another source video

    with self.env.begin(write=False) as txn:
        # key = format_for_lmdb(video_item['video_name'], 0)
        # img_bytes_1 = txn.get(key)
        # img1 = Image.open(BytesIO(img_bytes_1))
        # data['source_image'] = self.transform(img1)

        # cross-identity
        key = format_for_lmdb(video_item_src['video_name'], 0)
        img_bytes_1 = txn.get(key)
        img1 = Image.open(BytesIO(img_bytes_1))
        data['source_image'] = self.transform(img1) # source image

        semantics_key = format_for_lmdb(video_item_src['video_name'], 'coeff_3dmm')
        semantics_numpy = np.frombuffer(txn.get(semantics_key), dtype=np.float32)
        semantics_numpy = semantics_numpy.reshape((video_item_src['num_frame'], -1))
        source_semantics = self.transform_semantic(semantics_numpy, 0) # source semantic numpy

        semantics_key = format_for_lmdb(video_item['video_name'], 'coeff_3dmm')
        semantics_numpy = np.frombuffer(txn.get(semantics_key), dtype=np.float32)
        semantics_numpy = semantics_numpy.reshape((video_item['num_frame'],-1)) # target semantic numpy

        data['target_image'], data['target_semantics'] = [], []
        for frame_index in range(video_item['num_frame']):
            key = format_for_lmdb(video_item['video_name'], frame_index)
            img_bytes_1 = txn.get(key)
            img1 = Image.open(BytesIO(img_bytes_1))
            data['target_image'].append(self.transform(img1))
            target_semantics = self.transform_semantic(semantics_numpy, frame_index)

            target_semantics[-3:] = source_semantics[-3:] # replace the crop parameters of the target's with the source's

            data['target_semantics'].append(
                # self.transform_semantic(semantics_numpy, frame_index)
                target_semantics
            )
        data['video_name'] = video_item['video_name']
    return data

@kjzju Thanks, I will try again !

@DWCTOD have you figured out the issue about the cross identity motion imitation? I do agree with you that the identity information of the source image is not passed to generator model , and the result seems not preserving the source identity very well. @RenYurui, Have you tried to pass an extra more source identity coefficient to the generator model? Hope for your reply, thanks.

你好，这个问题还没有解决， 但是我猜测可能这部分的工作还没有分享出来，简单的通过3DMM参数传递应该是得不到作者demo的效果，应该是需要一个facial motion retarget的模块才能将cross-id 的运动比较自然有效的迁移过去

how use custom images instead video_item['video_name']
