EmotionCLIP Model

Project Overview

EmotionCLIP is an open-domain multimodal emotion perception model built on CLIP. This model aims to perform broad emotion recognition through multimodal inputs such as faces, scenes, and photos, supporting the analysis of emotional attributes in images, scene layouts, and even artworks.

Datasets

The model is trained using the following datasets:

1. EmoSet:

   • Citation:

     @inproceedings{yang2023emoset,
       title={EmoSet: A Large-Scale Visual Emotion Dataset with Rich Attributes},
       author={Yang, Jingyuan and Huang, Qirui and Ding, Tingting and Lischinski, Dani and Cohen-Or, Danny and Huang, Hui},
       booktitle={Proceedings of the IEEE/CVF International Conference on Computer Vision},
       pages={20383--20394},
       year={2023}
     }
     

   • This dataset contains rich emotional labels and visual features, providing a foundation for emotion perception.In this model, We use the dataset Emoset118K.

2. Open Human Facial Emotion Recognition Dataset:

   • Contains nearly 10,000 images with emotion labels gathered from wild scenes to enhance the model's capability in facial emotion recognition.

Prefix-Tuning

Fine-tuning Weights

This repository provides one fine-tuned weights:

1. EmotionCLIP Weights
   • Fine-tuned on the EmoSet 118K dataset, without additional training specifically for facial emotion recognition.
   • Final evaluation results:
     • Accuracy: 0.8042
     • Recall: 0.8042
     • F1: 0.8057

Usage Instructions

git clone https://huggingface.co/jiangchengchengNLP/EmotionCLIP

cd EmotionCLIP
# Create your own test file to store images ending in JPG, or organize images from the repository for testing
# By default, MixCLIP weights are used. Run the following python command in the current folder.

from EmotionCLIP import model, preprocess, tokenizer
from PIL import Image
import torch
import matplotlib.pyplot as plt
import os
from torch.nn import functional as F

# Image folder path
image_folder = r'./test'  #test images are in EmotionCLIP repo : jiangchengchengNLP/EmotionCLIP

# Emotion label mapping

    'sadness': 7,
    'neutral': 8
}

# Create subplots

# Iterate through each image
for idx, img_path in enumerate(image_files):
    # Load image
    img = Image.open(img_path)
    img_input = preprocess(img)

    # Predict emotion
    with torch.no_grad():

    softmax_logits_per_image = F.softmax(logits_per_image, dim=-1)
    top_k_values, top_k_indexes = torch.topk(softmax_logits_per_image, k=1, dim=-1)

    # Display image and prediction result
    ax = axes[idx]
