输入Y通道的低分辨率图像（单通道灰度图像），返回2倍超分辨率后的高清晰Y通道图像。模型基于Edgeoriented Convolution Block (ECB)模块构建，完整模型可导出为简洁的CNN网络，适用于移动端、嵌入式等严格限制算力的场景。为了适用于大部分移动端场景，模型只支持单通道图像处理，如果是RGB图像，需要将图像从RGB颜色空间转换为YCbCr格式并只提取Y通道部分输入给模型处理。完整模型结构如下所示：

模型描述

输入Y通道的低分辨率图像（单通道灰度图像），返回2倍超分辨率后的高清晰Y通道图像。模型基于Edgeoriented

Convolution Block (ECB)模块构建，完整模型可导出为简洁的CNN网络，适用于移动端、嵌入式等严格限制算力的场景。为了适用于大部分移动端场景，模型只支持单通道图像处理，如果是RGB图像，需要将图像从RGB颜色空间转换为YCbCr格式并只提取Y通道部分输入给模型处理。完整模型结构如下所示：

其中Edgeoriented Convolution Block (ECB)模块可以通过重参数化技术等价转换为一个普通的3x3卷积模块。

期望模型使用方式以及适用范围

本模型使用于移动端等算力限制严格的普通Y通道图像超分辨率。

如何使用

在ModelScope框架上，提供输入图像，即可通过简单的Pipeline调用来使用。

代码范例

模型局限性以及可能的偏差

本模型训练时使用经典的bicubic下采样从HR图像生成LR图像，以构造训练数据对，在其他严重降质场景效果可能不佳。本模型针对移动端和嵌入式芯片场景设计，在效果与算力之间作了折中。

Download the full repository or choose a version or file.

Download tools · More than GGUF

Use the Hugging Face download tool to obtain iic/cv_ecbsr_image-super-resolution_mobile. Download Safetensors, GGUF, ONNX, configuration and other repository files. Downloading does not mean the tool can run this model.

Pinned-version file information is being completed. Existing downloads remain available, or load the file manifest below.

Choose a mirror or official source, your operating system and download scope below, then copy the command. Install the download tool first if needed.

Pinned version: 8b147252803b486fdb1d652147109473fd0ca1bb. Downloads files only; does not start the model.

Choose a download source

Pinned ModelScope version: 8b147252803b486fdb1d652147109473fd0ca1bb. Version identifiers can differ across sites. The alternative source was provided after checking weights and runtime configuration; this is not proof of a successful model run.

A checked, pinned ModelScope source is available for this model. Use the ModelScope download tool.

Choose what to download

Need just one GGUF precision? Load the file manifest and choose a version. Direct file links do not require Python; the command below can download multiple shards together.

Quantization / file

This reads the pinned version's file manifest; no model weights are downloaded.

Choose your operating system

For command-line downloads, follow these steps to get the full repository or selected files. Direct file links do not need these steps.

Open a terminal window

Create and open a folder for the model. In the folder's address bar, enter powershell and press Enter.

If Python is not installed, get it from the official Python website. In the terminal, enter python --version; continue when a version number appears.

First time? Install the download tool

Copy this command, paste it into the terminal, press Enter and wait for installation to finish.

python -m pip install --upgrade huggingface_hub

Already installed? Continue to step 3.

Run the download command

Select the button below, paste into the same terminal and press Enter. The tool downloads all files included in the current command.

Copying does not start a download. Paste and run the command on your device.

Where are the downloaded files?

Open the folder you chose. Look for the models folder. When progress stops and the terminal returns to its prompt without errors, check that all files are present. 'Copied' does not mean 'downloaded'.

No response or an error?

python not found: Install Python and reopen the terminal. On Windows, follow the installer's instructions to enable command-line access.

hf not found: Confirm that step 2 succeeded, then reopen the terminal. If needed, add Python's Scripts folder to your user PATH. Do not repeatedly download scripts.

Network interrupted: Stay in the same folder and run the same command again. The tool checks existing files.

Permission or disk error: Choose a writable folder with enough free space. Do not disable system security protection.

Files transfer directly from the source you choose, not through Xianshe servers.

The version is pinned. Repeating the same command checks existing files. Change the source manually if it is slow or unavailable.

Public models do not require submitting keys to Xianshe. Restricted models still require the author's authorization. On Linux / macOS, use python3 instead of python when appropriate.
