Fine-grained CLIP fine-tuning with self-annotated region alignment

Contrastive Language-Image Pre-training (CLIP) has been shown to have limitations in its fine-grained dense feature representation, due to its pre-training focusing on matching the whole image to a text description. Considering the large data and computational burden in pre-training a vision-language model from scratch, a series of works aim to enhance the fine-grained ability of CLIP through a fine-tuning scheme.

ProCLIP: Progressive Vision-Language Alignment via LLM-based Embedder

ProCLIP introduces a curriculum‑learning framework that progressively aligns a CLIP image encoder with an LLM‑based text embedder. It first distills CLIP’s text encoder knowledge into the LLM embedder, then fine‑tunes the image encoder via contrastive learning with self‑distillation, instance semantic alignment, and embedding structure alignment losses. The approach addresses CLIP’s token limit, lack of multilingual support, and preserves pre‑trained vision‑language alignment.

0.5\%>100\%: Bidirectional Reciprocal Learning for Referring Image Segmentation

The paper introduces Bidirectional Reciprocal Learning (BRL), a parameter‑efficient fine‑tuning framework for referring image segmentation that operates on frozen vision foundation models. BRL employs two lightweight adapters—Reciprocal Attention Adapter (RAA) for token‑level cross‑modal attention and Reciprocal Gate Adapter (RGA) for channel‑level gating—to enable hierarchical, bidirectional information flow between vision and language. Experiments on RefCOCO, RefCOCO+, and RefCOCOg show that BRL outperforms existing methods while updating fewer than 0.5% of backbone parameters.
