Module upscale 

Neural and classical upscaling for textures and glyph maps.

Structs

UpscaleConfig

Configuration for the upscaler.

Upscaler

Neural upscaler wrapping a model.

Enums

UpscaleQuality

Quality preset for upscaling.

Functions

bicubic_upscale

Bicubic upscaling fallback. Input shape: (C, H, W).

bilinear_upscale

Bilinear upscaling fallback. Input shape: (C, H, W).

create_simple_upscaler

Create a simple ESPCN-style upscaler. The model learns a mapping from low-res features to high-res via sub-pixel convolution (simulated with dense layers).
