This paper summarizes the 2nd NTIRE challenge on stereo image super-resolution (SR) with a focus new solutions and results. The task of is to super-resolve low-resolution pair high-resolution one magnification factor ×4. Compared single SR, major this lies in how exploit additional information another viewpoint maintain consistency has 3 tracks, including track distortion (e.g., PSNR) bicubic degradation, perceptual quality LPIPS) as well real degradations. In total, 175, 93, 103...

We present Hunyuan3D 2.0, an advanced large-scale 3D synthesis system for generating high-resolution textured assets. This includes two foundation components: a shape generation model -- Hunyuan3D-DiT, and texture Hunyuan3D-Paint. The generative model, built on scalable flow-based diffusion transformer, aims to create geometry that properly aligns with given condition image, laying solid downstream applications. benefiting from strong geometric priors, produces vibrant maps either generated...

In this paper, a transmission-guided lightweight neural network called TGL-Net is proposed for efficient image dehazing. Unlike most current dehazing methods that produce simulated transmission maps from depth data and haze-free images, in the work, guided are computed automatically using filter-refined dark-channel-prior (F-DCP) method real-world hazy images as regularizer, which facilitates training not only on synthetic data, but also natural images. A double-error loss function combines...

Unsupervised image-to-image translation (UI2I) tasks aim to find a mapping between the source and target domains from unpaired training data. Previous methods can not effectively capture differences domain on different scales often leads poor quality of generated images, noise, distortion, other conditions that do match human vision perception, has high time complexity. To address this problem, we propose multi-scale structure progressive growth generator method solve UI2I task. Our refines...

Image haze removal techniques have a promising application prospects. However, color distortion by excessive dehazing is common problem especially for images containing light surface objects. To solve this problem, an improved image method based on dark channel prior with fidelity proposed in paper. First, filters (Sobel operator and mean filter) are used to refine the initial transmission map estimated from prior. Second, piecewise constrained function keep fidelity. Experimental results...

Novel view synthesis of dynamic scenes has been an intriguing yet challenging problem. Despite recent advancements, simultaneously achieving high-resolution photorealistic results, real-time rendering, and compact storage remains a formidable task. To address these challenges, we propose Spacetime Gaussian Feature Splatting as novel scene representation, composed three pivotal components. First, formulate expressive Gaussians by enhancing 3D with temporal opacity parametric motion/rotation....

Query optimizers have long been considered as among the most complex components of a database engine, while assessment an optimizer's quality remains challenging task. Indeed, existing performance benchmarks for engines (like TPC benchmarks) produce query runtime system rather than its optimizer. To address this challenge, paper introduces OptMark, toolkit evaluating OptMark is designed to offer number desirable properties. First, it decouples optimizer from underlying execution engine....
