# Documentation - Class name: ImageIntensityDetector - Category: ControlNet Preprocessors/Recolor - Output node: False ImageIntensityDetector 节点专门用于通过调整图像的强度水平来预处理图像。这种调整是通过伽马校正实现的,在进一步处理之前增强图像的整体可见度和对比度。 # Input types ## Required - image - 需要进行强度调整(通过伽马校正)的输入图像。 - Comfy dtype: IMAGE - Python dtype: numpy.ndarray ## Optional - gamma_correction - 指定用于调整图像强度的伽马校正因子。较高的值会使图像变亮,较低的值会使图像变暗,显著影响输出的视觉质量。 - Comfy dtype: FLOAT - Python dtype: float - resolution - 在应用强度调整之前,图像被调整到的分辨率,影响输出的细节水平。 - Comfy dtype: INT - Python dtype: int # Output types - image - 输出是一个经过强度水平调整的图像,适用于视觉分析或进一步的图像处理任务。 - Comfy dtype: IMAGE - Python dtype: numpy.ndarray ## Usage tips - Infra type: `CPU` - Common nodes: unknown ## Source code ```python class ImageIntensityDetector: @classmethod def INPUT_TYPES(s): #https://github.com/Mikubill/sd-webui-controlnet/blob/416c345072c9c2066101e225964e3986abe6945e/scripts/processor.py#L1229 return create_node_input_types( gamma_correction=("FLOAT", {"default": 1.0, "min": 0.1, "max": 2.0, "step": 0.001}) ) RETURN_TYPES = ("IMAGE",) FUNCTION = "execute" CATEGORY = "ControlNet Preprocessors/Recolor" def execute(self, image, gamma_correction, resolution=512, **kwargs): from controlnet_aux.recolor import Recolorizer return (common_annotator_call(Recolorizer(), image, mode="intensity", gamma_correction=gamma_correction , resolution=resolution), ) ```
