Coreml Realesrgan X4plus

Coreml Realesrgan X4plus is a Core ML model designed for image super-resolution and upscaling, distributed as a mirror of the original RealESRGAN-CoreML artifact. The model is intended for use in macOS and iOS applications, providing a 4x upscaling capability for images. Its architecture is based on RRDBNet, featuring 23 RRDB blocks, 64 features, and 32 growth channels. The model operates with Float16 precision, accepting input images of size (1, 3, 256, 256) in RGB format normalized to the [0, 1] range, and producing output images of size (1, 3, 1024, 1024) in the same format.

The repository serves as a distribution mirror for the Core ML artifact, which was originally published for use with the LocalMuse iOS app. The model archive is preserved unchanged from its original release. zip file, unzip it, and compile it using Core ML tools for integration into their own macOS or iOS projects.

Coreml Realesrgan X4plus is licensed under the BSD 3-Clause license, allowing for broad use and redistribution within the terms of that license. The model is specifically targeted at macOS 15 and later versions, as well as iOS platforms, supporting developers who wish to include image upscaling functionality in their Apple ecosystem applications. The model file size is approximately 33 MB as an mlpackage, or 30 MB when zipped.
