• SAM-CLIP Merging Vision Foundation Models towards Semantic and Spatial Understanding (15 Nov 2023)
  

  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.

• Subject-Diffusion Open Domain Personalized Text-to-Image Generation without Test-time Fine-tuning (26 Jul 2023)
  

  This is my reading note for Subject-Diffusion:Open Domain Personalized Text-to-Image Generation without Test-time Fine-tuning. This paper propose a diffusion method to generate images with given visual concepts and text prompt. Especially the paper is able to hand multiple visual concert jointly. To handle that, the paper detect the visual concepts from the input images, then the segmented images and bounding box are encoded feed into latent diffusion model. To enhance the consistency, the visual embedding is inserted into the text encode of the prompt.

• Segment Anything Meets Point Tracking (07 Jul 2023)
  

  This is my reading note for Segment Anything Meets Point Tracking. This paper combines SAM with point tracker to perform object segment and tracking in video. To to that it use point tracker to track points through the frames.for points of each frame SAM generate masks from the points promote. After every 8 frames, new points will be sampled from the mask.for best performance, 8 positive points and l negative points is recommended.
