Coin-CLIP 🪙 : Enhancing Coin Image Retrieval with CLIP
Model Details / 模型细节
This model (Coin-CLIP) is built upon
OpenAI's CLIP (ViT-B/32) model and fine-tuned on
a dataset of more than 340,000 coin images using contrastive learning techniques. This specialized model is designed to significantly improve feature extraction for coin images, leading to more accurate image-based search capabilities. Coin-CLIP combines the power of Visual Transformer (ViT) with CLIP's multimodal learning capabilities, specifically tailored for the numismatic domain.
Key Features:
- State-of-the-art coin image retrieval;
- Enhanced feature extraction for numismatic images;
- Seamless integration with CLIP's multimodal learning.
本模型（Coin-CLIP）
在 OpenAI 的 CLIP (ViT-B/32) 模型基础上，利用对比学习技术在超过 340,000 张硬币图片数据上微调得到的。
Coin-CLIP 旨在提高模型针对硬币图片的特征提取能力，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，并专门针对硬币图片进行了优化。

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。
