Description

w2xncnnvk is a ncnn implementation of waifu2x converter, based on waifu2x-ncnn-vulkan.

This is a port of the VapourSynth plugin w2xncnnvk.Waifu2x.

Requirements

• Vulkan compatible device
• AviSynth+ r3682 (can be downloaded from here until official release is uploaded) or later
• Microsoft VisualC++ Redistributable Package 2022 (can be downloaded from here)
• Supported color formats: RGBPS
• models must be located in the same folder as w2xncnnvk.

Syntax and Parameters

w2xncnnvk (clip input, int "noise", int "scale", int "tile_w", int "tile_h", int "model", int "gpu_id", int "gpu_thread", bool "tta", bool "fp32", bool "list_gpu")

clip  input =

A clip to process.

It must be in RGB 32-bit planar format.

int  noise = 0

Denoise level.

Large value means strong denoise effect, -1 - no effect.

Must be between -1..3.

Default: 0.

int  scale = 2

Upscale ratio.

Must be either 1 or 2.

Default: 2.

int  tile_w = input_width

int  tile_h = input_height

Tile width and height, respectively.

Use smaller value to reduce GPU memory usage.

Must be equal to or greater than 32.

Default: input_width, input_height.

int  model = 2

Model to use.

• 0: upconv_7_anime_style_art_rgb
• 1: upconv_7_photo
• 2: cunet

Default: 2.

int  gpu_id =

GPU device to use.

By default the default device is selected.

int  gpu_thread = 2

Thread count for upscaling.

Using larger values may increase GPU usage and consume more GPU memory. If you find that your GPU is hungry, try increasing thread count to achieve faster processing.

Default: 2.

bool  tta = false

Enable TTA(Test-Time Augmentation) mode.

Default: False.

bool  fp32 = false

Enable FP32 mode.

Default: False.

bool  list_gpu = false

Simply print a list of available GPU devices on the frame and does nothing else.

Default: False.

Examples

w2xncnnvk with default settings:

ColorBars(pixel_type="RGBPS")
w2xncnnvk(noise=0, scale=2, model=2, gpu_thread=2, tta=false, fp32=false, list_gpu=false)
