🔧 Image Enhance Difference¶
Documentation¶
- Class name:
ImageEnhanceDifference+
- Category:
essentials
- Output node:
False
This node is designed to enhance the difference between two images by applying a power transformation. It aims to highlight the disparities between the images, potentially for further analysis or visual effect enhancement.
Input types¶
Required¶
image1
- The first image to compare. It serves as the baseline for the enhancement process.
- Comfy dtype:
IMAGE
- Python dtype:
torch.Tensor
image2
- The second image to compare. This image is adjusted to match the first image's dimensions if necessary, before the difference enhancement.
- Comfy dtype:
IMAGE
- Python dtype:
torch.Tensor
exponent
- A factor that controls the intensity of the enhancement. Higher values increase the contrast between the differences.
- Comfy dtype:
FLOAT
- Python dtype:
float
Output types¶
image
- Comfy dtype:
IMAGE
- The enhanced difference image, highlighting disparities between the input images.
- Python dtype:
torch.Tensor
- Comfy dtype:
Usage tips¶
- Infra type:
GPU
- Common nodes: unknown
