Computer vision systems, such as object detection, traditionally rely on supervised learning and predetermined categories, an approach facing limitations when applied to infrared images due to dataset constraints. Emerging contrastive vision-language models, like (Contrastive Language-Image Pre-Training) CLIP, offer a transformative approach through their pre-training on extensive image-text pairs, providing diverse visual representations integrated with language semantics.
Our work proposes a novel zero-shot object detection approach for infrared images by extending the benefits of CLIP into this domain. We have developed a two-stage detection system using CLIP for detecting humans in infrared images. The first stage involves region proposal by a (You Only Look Once) YOLO object detector, followed by CLIP in the second stage. When compared with a YOLO model fine-tuned using infrared images, our proposed system demonstrates comparable performance, illustrating its efficacy as a zero-shot object detection approach. This method opens up new avenues for infrared image processing leveraging the capabilities of foundation models.
