# VisionReward-Image
|
|
|
|
## Introduction
|
|
We present VisionReward, a general strategy to aligning visual generation models——both image and video generation——with human preferences through a fine-grainedand multi-dimensional framework. We decompose human preferences in images and videos into multiple dimensions,each represented by a series of judgment questions, linearly weighted and summed to an interpretable and accuratescore. To address the challenges of video quality assess-ment, we systematically analyze various dynamic features of videos, which helps VisionReward surpass VideoScore by 17.2% and achieve top performance for video preference prediction.
|
|
Here, we present the model of VisionReward-Image.
|
|
|
|
## Merging and Extracting Checkpoint Files
|
|
Use the following command to merge the split files into a single `.tar` file and then extract it into the specified directory:
|
|
|
|
```sh
|
|
cat ckpts/split_part_* > ckpts/visionreward_image.tar
|
|
tar -xvf ckpts/visionreward_image.tar
|
|
```
|
|
|
|
## Using this model
|
|
You can quickly install the Python package dependencies and run model inference in our [github](https://github.com/THUDM/VisionReward). |
