Abstract

When adapting self-supervised Vision Transformers (ViTs) to dense prediction, existing methods often treat the ViT as a passive feature extractor and may underuse the rich priors encoded in its representations, including saliency, global context, and high-frequency details. We propose SAGE (Saliency-Annealed Gated Encoder), an enhanced ViT-Adapter backbone that explicitly exploits these priors through three complementary innovations: (1) a saliency-guided architecture that extracts DINO-style class-token (CLS) saliency to guide feature gating and high-frequency enhancement, together with dynamic multi-layer aggregation and a local-detail branch; (2) an annealing-based training paradigm designed to improve convergence and feature quality during early training while reducing feature drift later in training; and (3) a two-stage, quality-aware training mechanism that smoothly transitions from focal loss to Varifocal Loss (VFL) within a single training run. Across the evaluated tasks (Fig.~\ref{fig:fig_com}), SAGE achieves state-of-the-art (SOTA) or competitive results on COCO (62.8 box AP and 55.3 mask AP), COCO keypoint estimation (78.5 AP), ADE20K (60.3 mIoU for semantic segmentation and 44.9 mask AP for instance segmentation), TinyImageNet classification (94.76% Top-1 accuracy), and DIOR-R oriented object detection (78.8 AP $_{50}$ ). The same backbone is used across tasks, with task-specific decoders. To the best of our knowledge, SAGE is the first framework to achieve multi-task state-of-the-art results on Huawei Ascend NPUs. Code and pretrained models will be released after internal review.

Fig. 2: Overview of the SAGE architecture. The input image is processed in three parallel paths: (1) SPM CNN pyramid generating multi-scale features

\mathbf{C}_{1:4}

; (2) ViT backbone producing all layer outputs (patch/CLS/register tokens), from which the saliency prior

\mathbf{S}

and multi-depth aggregated features

\hat{\mathbf{X}}_{1:4}

are derived; (3) a 2

\times

2 local-detail branch extracting

\mathbf{L}

. The aggregated features are per-scale enhanced (HF/FiLM), interact with SPM queries via MSDeformAttn, and are fused through residual soft gating (

\mathbf{F}_{i}=\mathbf{F}_{spm,i}+\mathbf{X}_{vit,i}\cdot\mathbf{G}_{i}

) and difference-aware local fusion, followed by SyncBN and a task-specific decoder. (a) CLS–Patch similarity prior:

\mathbf{S}

from 2/3-depth tokens via L2-norm cosine similarity, standardization, sigmoid. (b) Multi-depth aggregation: sampled layers fused into

\hat{\mathbf{X}}_{1:4}

via temperature-softmax weights. (c) Difference-aware local fusion:

\mathbf{Y}_{i}=\mathbf{F}_{i}+\sigma(\text{GateNet}([\mathbf{F}_{i},\mathbf{L}^{\prime},|\mathbf{F}_{i}-\mathbf{L}^{\prime}|]))\odot\mathbf{L}^{\prime}

for high-resolution scales.

ViT-Up: Faithful Feature Upsampling for Vision Transformers

Semantic Correspondence Vision Transformer Semantic Segmentation

Open paper AskPDF arXiv

Vision Transformers (ViTs) have become a dominant architecture for visual representation learning, providing exceptionally strong and broadly reusable backbone features. However, ViTs are commonly operated on relatively small patch-token grids due to the quadratic cost of global self-attention, which creates a persistent bottleneck for dense prediction tasks such as semantic segmentation and depth estimation. This has motivated the development of task-agnostic feature upsamplers. While recent state-of-the-art methods produce visually sharp dense representations, their reliance on shallow image encoders for guided upsampling can introduce feature leakage, fragmentation, and blur. We introduce ViT-Up, an implicit feature upsampling framework that replaces external image guidance with layer-wise query construction from intermediate ViT hidden states. This enables feature prediction at arbitrary continuous image coordinates while preserving alignment with the backbone feature space. Experiments demonstrate that ViT-Up consistently outperforms state-of-the-art image-guided upsamplers across dense prediction and semantic correspondence. On DINOv3-S+, ViT-Up improves over prior methods by up to +2.07 mIoU on Cityscapes and +4.17 [email protected] on SPair-71k. With the larger DINOv3-B backbone, these gains increase to +3.36 mIoU and +8.09 [email protected], demonstrating that ViT-Up scales favorably with backbone capacity.
