LLaVA-UHD v3: Progressive Visual Compression for Efficient Native-Resolution Encoding in MLLMs

ReMatch has been introduced as a new framework that utilizes the generative capabilities of Multimodal Large Language Models (MLLMs) for enhanced multimodal retrieval. This approach trains the MLLM end-to-end, employing a chat-style generative matching stage that assesses relevance from various inputs, including raw data and projected embeddings.

The introduction of DinoLizer, a model based on DINOv2, aims to enhance the localization of manipulated regions in generative inpainting. By utilizing a pretrained DINOv2 model on the B-Free dataset, it incorporates a linear classification head to predict manipulations at a granular patch resolution, employing a sliding-window strategy for larger images. This method shows superior performance compared to existing local manipulation detectors across various datasets.

A new benchmark called CaptionQA has been introduced to evaluate the utility of model-generated captions in supporting downstream tasks across various domains, including Natural, Document, E-commerce, and Embodied AI. This benchmark consists of 33,027 annotated multiple-choice questions that require visual information to answer, aiming to assess whether captions can effectively replace images in multimodal systems.

A new training framework named Monet has been introduced to enhance multimodal large language models (MLLMs) by enabling them to reason directly within latent visual spaces, generating continuous embeddings as intermediate visual thoughts. This approach addresses the limitations of existing methods that rely heavily on external tools for visual reasoning.

CAPability has been introduced as a comprehensive visual caption benchmark designed to evaluate the correctness and thoroughness of captions generated by multimodal large language models (MLLMs). This benchmark addresses the limitations of existing visual captioning assessments, which often rely on brief ground-truth sentences and traditional metrics that fail to capture detailed captioning effectively.

A new model named SMARC has been introduced, enabling surface material reconstruction and classification from minimal visual cues, specifically using just a 10% contiguous patch of an image. This approach addresses the limitations of existing methods that require dense observations, making it particularly useful in constrained environments.

A new framework named STVG-o1 has been introduced to enhance spatio-temporal video grounding (STVG) by enabling multimodal large language models (MLLMs) to achieve state-of-the-art performance without architectural changes. This framework employs a bounding-box chain-of-thought mechanism and a multi-dimensional reinforcement reward function to improve localization accuracy in untrimmed videos based on natural language descriptions.

A new automated histopathologic assessment framework for Hirschsprung Disease has been developed using a multi-stage Vision Transformer approach. This framework effectively segments the muscularis propria, delineates the myenteric plexus, and identifies ganglion cells, achieving a Dice coefficient of 89.9% and a Plexus Inclusion Rate of 100% across 30 whole-slide images with expert annotations.
