Image Normalize -1 to 1

Documentation

• Class name: ImageNormalize_Neg1_To_1
• Category: KJNodes/image
• Output node: False

This node is designed to adjust the pixel values of images so that they fall within the range of -1 to 1, effectively normalizing them for further processing or analysis.

Input types

Required

• images
  • The images to be normalized. This input is crucial for the operation as it directly affects the normalization process by scaling the pixel values.
  • Comfy dtype: IMAGE
  • Python dtype: torch.Tensor

Output types

• image
  • Comfy dtype: IMAGE
  • The normalized images, with pixel values adjusted to fall within the range of -1 to 1.
  • Python dtype: torch.Tensor

Usage tips

• Infra type: GPU
• Common nodes: unknown
