 The implementation of paper [**SegCLIP: Patch Aggregation with Learnable Centers for Open-Vocabulary Semantic Segmentation**](https://arxiv.org/abs/2211.14813). 
 
-> In this paper, we propose a CLIP-based model named SegCLIP for the topic of open-vocabulary segmentation in an annotation-free manner. The SegCLIP achieves segmentation based on ViT and the main idea is to gather patches with learnable centers to semantic regions through training on text-image pairs. The gathering operation can dynamically capture the semantic groups, which can be used to generate the final segmentation results. We further propose a reconstruction loss on masked patches and a superpixel-based KL loss with pseudo-labels to enhance the visual representation. Experimental results show that our model achieves comparable or superior segmentation accuracy on the PASCAL VOC 2012 (+1.4\% mIoU), PASCAL Context (+2.4\% mIoU), and COCO (+5.6\% mIoU) compared with baselines.
