ARTDECO: Towards Efficient and High-Fidelity On-the-Fly 3D Reconstruction with Structured Scene Representation
On-the-fly 3D reconstruction from monocular image sequences is a long-standing challenge in computer vision, critical for applications such as real-to-sim, AR/VR, and robotics. Existing methods face a major tradeoff: per-scene optimization yields high fidelity but is computationally expensive, whereas feed-forward foundation models enable real-time inference but struggle with accuracy and robustness. In this work, we propose ARTDECO, a unified framework that combines the efficiency of feed-forw…

That's how our hike at the #mummelsee started ... and how it was when we were up there. - But the walk was quite okay.
We checked the rain radar and decided to go back down rather quickly. We leveraged our rain gear and it did not disappoint us! 🙂
So we didn't see the area atop - the so called

Perched atop a densely forested hillside, a quaint observation tower and building overlook a tranquil scene. The lush, evergreen forest—rich with deep greens and hints of lighter foliage—cascades down toward a calm, reflective lake below. The sky above is overcast, casting a soft, diffused light that mutes the colors into soothing tones, creating an atmosphere of quiet serenity. The structure at the summit, partially obscured by the treetops, suggests a rewarding destination for hikers seeking…
A quiet, winding trail meanders through a lush forest, inviting exploration into its verdant depths. Towering trees, their trunks a mix of muted browns and grays, stretch upward to form a dense canopy overhead, filtering the soft, diffused light that gently illuminates the path. The forest floor is a tapestry of earthy tones, with scattered stones and roots peeking through a bed of pine needles and fallen leaves. To the right, a rocky slope is adorned with vibrant green moss and delicate ferns…
Shrouded in a veil of soft, misty gray, a solitary stone tower rises from the foggy highlands, its rugged silhouette blending seamlessly with the muted tones of the overcast sky. The tower, sturdy and timeless, is accompanied by a quaint building with a green-tinged roof, its wooden bench inviting weary hikers to rest. The gravel path leading to the structure hints at countless journeys taken, each step a story of adventure and exploration. The atmosphere is one of quiet mystery and contemplat…
A misty veil of soft gray clouds lingers over this tranquil mountain lake, creating an air of quiet mystery. The dense forest, a lush tapestry of evergreen pines and scattered deciduous shrubs, frames the still waters below. Vibrant green foliage contrasts subtly with the muted tones of weathered rocks in the foreground, adding texture to the scene. The lake itself rests peacefully, its surface barely disturbed, reflecting the muted light filtering through the overcast sky. A faint outline of …

IIET: Efficient Numerical Transformer via Implicit Iterative Euler Method
High-order numerical methods enhance Transformer performance in tasks like NLP and CV, but introduce a performance-efficiency trade-off due to increased computational overhead. Our analysis reveals that conventional efficiency techniques, such as distillation, can be detrimental to the performance of these models, exemplified by PCformer. To explore more optimizable ODE-based Transformer architectures, we propose the \textbf{I}terative \textbf{I}mplicit \textbf{E}uler \textbf{T}ransformer \text…

Why all roads don't lead to Rome: Representation geometry varies across the human visual cortical hierarchy
Biological and artificial intelligence systems navigate the fundamental efficiency-robustness tradeoff for optimal encoding, i.e., they must efficiently encode numerous attributes of the input space while also being robust to noise. This challenge is particularly evident in hierarchical processing systems like the human brain. With a view towards understanding how systems navigate the efficiency-robustness tradeoff, we turned to a population geometry framework for analyzing representations in t…

Secure Semantic Communication over Wiretap Channels: Rate-Distortion-Equivocation Tradeoff
This paper investigates an information-theoretic model of secure semantic-aware communication. For this purpose, we consider the lossy joint source-channel coding (JSCC) of a memoryless semantic source transmitted over a memoryless wiretap channel. The source consists of two correlated parts that represent semantic and observed aspects of the information. Our model assumes separate fidelity and secrecy constraints on each source component and, in addition, encompasses two cases for the source o…
