# Documentation
|
||||
- Class name: Inference_Core_SAMPreprocessor
|
||||
- Category: ControlNet Preprocessors/others
|
||||
- Output node: False
|
||||
|
||||
SAM预处理器节点旨在使用SAM(Segment Anything Model)架构对图像进行分割。它利用预训练的SAM模型来处理图像,根据需要调整图像分辨率,并返回分割后的输出。
|
||||
|
||||
# Input types
|
||||
## Required
|
||||
- image
|
||||
- 需要进行分割的输入图像。这是SAM预处理器操作的主要数据,用于确定图像中的感兴趣区域。
|
||||
- Comfy dtype: IMAGE
|
||||
- Python dtype: torch.Tensor
|
||||
|
||||
## Optional
|
||||
- resolution
|
||||
- 指定在分割之前应将输入图像缩放到的分辨率。这会影响分割输出的精细度和质量。
|
||||
- Comfy dtype: INT
|
||||
- Python dtype: int
|
||||
|
||||
# Output types
|
||||
- image
|
||||
- 输入图像的分割版本,突出显示由SAM模型确定的不同区域。
|
||||
- Comfy dtype: IMAGE
|
||||
- Python dtype: torch.Tensor
|
||||
|
||||
|
||||
## Usage tips
|
||||
- Infra type: `GPU`
|
||||
- Common nodes: unknown
|
||||
|
||||
|
||||
## Source code
|
||||
```python
|
||||
class SAM_Preprocessor:
|
||||
@classmethod
|
||||
def INPUT_TYPES(s):
|
||||
return create_node_input_types()
|
||||
|
||||
RETURN_TYPES = ("IMAGE",)
|
||||
FUNCTION = "execute"
|
||||
|
||||
CATEGORY = "ControlNet Preprocessors/others"
|
||||
|
||||
def execute(self, image, resolution=512, **kwargs):
|
||||
from controlnet_aux.sam import SamDetector
|
||||
|
||||
mobile_sam = SamDetector.from_pretrained().to(model_management.get_torch_device())
|
||||
out = common_annotator_call(mobile_sam, image, resolution=resolution)
|
||||
del mobile_sam
|
||||
return (out, )
|
||||
|
||||
```
