NAFNet-SIDD Core ML ModelsMIT + Apache-2.0 notices
Purpose: optional on-device image denoising using NAFNet-SIDD width64 and width32 models. The app prefers width64 for quality and can fall back to width32 or Core Image processing.

The pretrained checkpoints were converted locally to Core ML ML Program format. Input uses a 1 × 3 × 256 × 256 RGB tensor normalized to [0, 1]. The AI path requires iOS 18 or later.
用途：通过 NAFNet-SIDD width64 与 width32 模型在设备端进行可选图像降噪。App 优先使用质量更高的 width64，并可回退至 width32 或 Core Image 处理。

License: BSD 3-Clause.
The model accepts a 1 × 3 × 256 × 256 Float16 RGB tensor and produces a 1 × 3 × 1024 × 1024 result. The AI path requires iOS 18 or later and falls back to local non-AI processing when unavailable.
用途：使用 RRDBNet RealESRGAN_x4plus 架构，在设备端进行可选的 4× 图像超分辨率处理。
