SAM-CLIP Merging Vision Foundation Models towards Semantic and Spatial Understanding

This is my reading note for SAM-CLIP: Merging Vision Foundation Models towards Semantic and Spatial Understanding. This paper proposes a method to combine clip and Sam to perform zero shot semantic segmentation. To combined model merges the vision encoder of Sam and clip, but freezes the other encoders and heads. To avoid catastrophe forgetting, The paper uses two stage method, in first stage, only CLIP’S head is fine tuned; in second stage, the shared vision encode and two heads are fine tuned in a multi task way.

Chatting Makes Perfect Chat-based Image Retrieval

This is my reading note for [Chatting Makes Perfect: Chat-based Image Retrieval]. This paper proposes a method on using dialog (questions and answer pairs) to improve text based image retrieval. It experimented with different questioners (human, chatGPT and other LLM) and different answers (human, BLIP2). It showed that, dialog could significantly improves the retrieval performance. However, only chatGPT and human questioners could improve performance with more rounds of conversation.

mPLUG-Owl2 Revolutionizing Multi-modal Large Language Model with Modality Collaboration

This is my reading note for mPLUG-Owl2: Revolutionizing Multi-modal Large Language Model with Modality Collaboration. This paper proposes a method to unify visual and text data for multi modal model. To this end, it uses QFormer to extract visual information and concatenate to text and feed to LLM. However, it separates the projection layer and layer norm for visual and text. This paper is similar to COGVLM.

CoVLM Composing Visual Entities and Relationships in Large Language Models Via Communicative Decoding

This is my reading note for CoVLM: Composing Visual Entities and Relationships in Large Language Models Via Communicative Decoding. This paper proposes a vision language model to improve the capabilities of modeling composition relationship of objects across visual and text. To do that, it interleaves between language model generating special tokens and vision object detector detecting objects from image.
