# Model Card: Pix2Text-MFR
Math Formula Recognition (MFR) model from [Pix2Text (P2T)]().

## Model Details / 模型细节

This model is fine-tuned on a coin dataset using **contrastive learning** techniques, based on OpenAI's CLIP (ViT-B/32). It aims to enhance the feature extraction capabilities for **Coin** images, thus achieving more accurate image-based search functionalities. The model combines the powerful features of the Vision Transformer (ViT) with the multimodal learning capabilities of CLIP, specifically optimized for coin imagery.

这个模型是在 OpenAI 的 CLIP (ViT-B/32) 基础上，利用对比学习技术并使用硬币数据集进行微调得到的。它旨在提高硬币图像的特征提取能力，从而实现更准确的以图搜图功能。该模型结合了视觉变换器（ViT）的强大功能和 CLIP 的多模态学习能力，专门针对硬币图像进行了优化。



## Usage and Limitations / 使用和限制

- **Usage**: This model is primarily used for extracting representation vectors from coin images, enabling efficient and precise image-based searches in a coin image database.
- **Limitations**: As the model is trained specifically on coin images, it may not perform well on non-coin images.




- **用途**：此模型主要用于提取硬币图片的表示向量，以实现在硬币图像库中进行高效、精确的以图搜图。
- **限制**：由于模型是针对硬币图像进行训练的，因此在处理非硬币图像时可能效果不佳。
