• Abstract: Vision-language tracking (VLT) extends traditional single object tracking by incorporating textual information, providing semantic guidance to enhance tracking performance under challenging conditions like fast motion and deformations. However, current VLT trackers often underperform compared to single-modality methods on multiple benchmarks, with semantic information sometimes becoming a "distraction." To address this, we propose VLTVerse, the first fine-grained evaluation framework for VLT trackers that comprehensively considers multiple challenge factors and diverse semantic information, hoping to reveal the role of language in VLT. Our contributions include: (1) VLTVerse introduces 10 sequence-level challenge labels and 6 types of multi-granularity semantic information, creating a flexible and multi-dimensional evaluation space for VLT; (2) leveraging 60 subspaces formed by combinations of challenge factors and semantic types, we conduct systematic fine-grained evaluations of three mainstream SOTA VLT trackers, uncovering their performance bottlenecks across complex scenarios and offering a novel perspective on VLT evaluation; (3) through decoupled analysis of experimental results, we examine the impact of various semantic types on specific challenge factors in relation to different algorithms, providing essential guidance for enhancing VLT across data, evaluation, and algorithmic dimensions. The VLTVerse, toolkit, and results will be available at \url{http://metaverse.aitestunion.com}.

  Large language models (LLMs) showcase varied multilingual capabilities across tasks like translation, code generation, and reasoning. Previous assessments often limited their scope to fundamental natural language processing (NLP) or isolated capability-specific tasks. We present a pipeline for selecting available and reasonable benchmarks from massive ones, addressing the oversight in previous work regarding the utility of these benchmarks. We introduce P-MMEval, a large-scale benchmark covering effective fundamental and capability-specialized datasets.

  Visual Language Tracking (VLT) enhances tracking by mitigating the limitations of relying solely on the visual modality. Current VLT benchmarks do not account for multi-round interactions during tracking. We propose a novel and robust benchmark, VLT-MI, which introduces multi-round interaction into the VLT task for the first time.

  We propose a new multi-object tracking framework, named LG-MOT, that explicitly leverages language information at different levels of granularity. At inference, our LG-MOT uses the standard visual features without relying on annotated language descriptions. Our LG-MOT achieves an absolute gain of 2.2% in terms of target object association (IDF1 score) compared to the baseline using only visual features.

  Visual Language Tracking (VLT) enhances single object tracking (SOT) by integrating natural language descriptions from a video, for the precise tracking of a specified object. Most VLT benchmarks are annotated in a single granularity and lack a coherent semantic framework to provide scientific guidance. We introduce DTLLM-VLT, which automatically generates extensive and multi-granularity text to enhance environmental diversity.

  Vision Transformers (ViTs) have become increasingly popular in large-scale Vision and Language Pre-training models. Previous research has demonstrated the efficacy of ViTs, but they still struggle with computational inefficiencies caused by lengthy visual sequences. We introduce TRIPS, which reduces the visual sequence using a text-guided patch-selection layer in the visual backbone. Our experimental results reveal that TRIPS delivers a 40% speedup, while maintaining competitive or superior performance on downstream tasks.

We offer a detailed categorization for existing VLIT datasets and identify the characteristics that high-quality VLIT data should possess. By incorporating these characteristics as guiding principles into the existing VLIT data construction process, we conduct extensive experiments and verify their positive impact on the performance of tuned multi-modal LLMs.

• Divert More Attention to Vision-Language Object Tracking [87.31882921111048]
  We argue that the lack of large-scale vision-language annotated videos and ineffective vision-language interaction learning motivate us to design more effective vision-language representation for tracking. Particularly, in this paper, we first propose a general attribute annotation strategy to decorate videos in six popular tracking benchmarks, which contributes a large-scale vision-language tracking database with more than 23,000 videos. We then introduce a novel framework to improve tracking by learning a unified-adaptive VL representation, where the cores are the proposed asymmetric architecture search and modality mixer (ModaMixer)
