# SOIBench: Semantic Guidance in SOT

SOIBench is a benchmark for **semantic cognitive guidance** in **single object tracking** (SOT), introduced to isolate and evaluate failures caused by **Similar Object Interference** (SOI), a condition in which non-target objects resemble the designated target closely enough to induce multiple high-confidence peaks in a tracker’s confidence heat-map [2508.09524]. The benchmark is built on the premise that modern SOT systems, including Siamese-based and Transformer-based trackers, rely predominantly on shallow appearance matching and therefore exhibit persistent drift when fine-grained semantic discrimination is required. SOIBench operationalizes this problem by automatically mining SOI frames, annotating them with hierarchical natural-language guidance, and evaluating both vision-language tracking and VLM-assisted correction under controlled SOI-specific settings.

## 1. Similar Object Interference as a tracking bottleneck

SOI refers to situations in single-object tracking where one or more non-target objects visually resemble the designated target so closely in color, shape, texture, or context that the tracker’s confidence heat-map exhibits multiple high-confidence peaks. These multi-peak responses indicate ambiguous visual evidence and are associated with continuous fine-grained discrimination failures, ultimately producing drift [2508.09524].

Within the SOIBench formulation, the significance of SOI is not merely that distractors exist, but that they are sufficiently target-like to induce a structured failure mode that conventional aggregate tracking benchmarks do not isolate. Prior benchmarks report overall performance without separating SOI-driven errors from other sources of degradation. This creates a measurement problem: trackers may appear competitive in aggregate while remaining fundamentally weak in the specific regime where semantic disambiguation is required.

The benchmark’s central claim is that SOI is a primary constraint on robust SOT
