Fixed pattern noise (FPN) is a temporally constant noise present on videos due to the non-uniformities of the sensors that may exhibit spatial correlation, typically across columns and/or rows.
Acquiring real clean/noisy data is particularly challenging in the case of FPN, leading supervised FPN denoising networks to train using generated data.
Self-supervised approaches for denoising allow training directly on real noisy sequences, avoiding the biases introduced by synthetic data.

GEOSCALER: GEOMETRY AND RENDERING-AWARE DOWNSAMPLING OF 3D MESH TEXTURES: High-resolution texture maps are necessary to accurately represent real-world objects with 3D meshes. The large sizes of textures can bottleneck the real-time rendering of high-quality virtual 3D scenes on devices that have low computational budgets and limited memory. Downsampling the texture maps directly addresses the issue, albeit at the cost of visual fidelity. Traditionally, downsampling of texture maps is performed using methods such as bicubic interpolation and the Lanczos algorithm.

Point cloud compression is a critical component in 3D vision systems utilizing point cloud data to represent the physical world. Existing works on point cloud compression separately tackle Octree-based and Feature-based compression of point clouds despite their underlying similarities. In this work, we present UniFHiD: a unified fully hierarchical model for dynamic point cloud compression, that synergizes Octree and Feature Coding under a single model with shared parameters. The key enabler in this unification is the aligned feature extraction between the two coding methods.

Recent advancements in text-to-image (T2I) have improved synthesis results, but challenges remain in layout control and generating omnidirectional panoramic images. Dense T2I (DT2I) and spherical T2I (ST2I) models address these issues, but so far no unified approach exists. Trivial approaches, like prompting a DT2I model to generate panoramas can not generate proper spherical distortions and seamless transitions at the borders. Our work shows that spherical dense text-to-image (SDT2I) can be achieved by integrating training-free DT2I approaches into finetuned panorama models.

In this supplementary material, we provide implementation details of our method, training details of our method, additional experiments and visual results.

Despeckling of Synthetic Aperture Radar (SAR) images has seen significant progress in recent years, largely driven by advancements in deep learning techniques. However, many of these approaches face challenges when applied to new SAR datasets, primarily due to their dependence on ground truth images, which are often unavailable for real-world sensors. In this paper, we address this limitation by extending the concept of unbiased risk estimation in the presence of Gamma-distributed multiplicative speckle.
