Summary

Zero-shot object detection models, such as Grounding DINO, OWL-ViT, and DETIC, enable the identification of objects within images using text prompts without requiring the training of custom models. These models are trained on extensive datasets to recognize a broad spectrum of objects, providing a versatile tool for automatic image labeling and analysis. Despite their capabilities, zero-shot models are computationally demanding and may not perform efficiently in real-time or edge applications, making them impractical for large-scale deployment. As a solution, these models can be used to label data for training smaller, fine-tuned models like YOLOv8, which are more suitable for real-time deployment. While zero-shot models can effectively detect common objects, they may struggle with identifying specific or uncommon items, suggesting that fine-tuning might still be necessary for specialized tasks. The ongoing development of zero-shot models indicates potential advancements in object classification, detection, and segmentation, promising to enhance the capabilities of computer vision without the need for extensive training.
