MNJER

The model must meet the following requirements:

• File format: .onnx
• Input shape: [1, 3, H, W] (NCHW format)
• Input type: float32
• Input range: 0-1 (normalized RGB values)
• Output shape: [1, 3, H*scale, W*scale]
• Output type: float32
• Output range: 0-1 (normalized RGB values)

Note: This tool was made for ESRGAN models, but it should work with any ESRGAN-like model that has the same input and output dimensions.

The three dropdowns control the waifu2x model variant:

• First Dropdown (Type): Selects the model type based on the input image (e.g., Art, Art Scan, Photo).
• Second Dropdown (Noise): Sets the noise reduction level (0-3). Level 0 applies no noise reduction and is best for clean images. Higher levels reduce noise but may slightly decrease detail.
• Third Dropdown (Scale): Determines the upscaling factor (1x, 2x, or 4x). 1x applies only noise reduction without upscaling.
