- Parameters
generator (dict) – Config for the generator structure.
pixel_loss (dict) – Config for pixel-wise loss.
train_cfg (dict) – Config for training. Default: None.
test_cfg (dict) – Config for testing. Default: None.
required_frames (int) – Required frames in each process. Default: 2
step_frames (int) – Step size of video frame interpolation. Default: 1
init_cfg (dict, optional) – The weight initialized config for
BaseModule
.data_preprocessor (dict, optional) – The pre-process config of
BaseDataPreprocessor
.
- init_cfg¶
Initialization config dict.
- Type
dict, optional
- data_preprocessor¶
Used for pre-processing data sampled by dataloader to the format accepted by
forward()
.- Type
BaseDataPreprocessor
- static merge_frames(input_tensors, output_tensors)[source]¶
merge input frames and output frames.
Interpolate a frame between the given two frames.
- Merged from
[[in1, in2, in3, in4], [in2, in3, in4, in5], …] [[out1], [out2], [out3], …]
- to
[in1, in2, out1, in3, out2, …, in(-3), out(-1), in(-2), in(-1)]
- Parameters
input_tensors (Tensor) – The input frames with shape [n, 4, c, h, w]
output_tensors (Tensor) – The output frames with shape [n, 1, c, h, w].
- Returns
The final frames.
- Return type
list[np.array]
