Back to Point: Exploring Point-Language Models for Zero-Shot 3D Anomaly Detection
arXiv:2603.21511v2 Announce Type: replace Abstract: Zero-shot (ZS) 3D anomaly detection is crucial for reliable industrial inspection, as it enables detecting and localizing defects without requiring any target-category training data. Existing approaches render 3D point clouds into 2D images and leverage pre-trained Vision-Language Models (VLMs) for anomaly detection. However, such strategies inevitably discard geometric details and exhibit limited sensitivity to local anomalies.
I2PRef: Image-Driven Point Completion with Iterative Refinement
Announce Type: replace Abstract: We present an image-conditioned point cloud completion approach that treats images as the primary geometric source rather than a secondary guide. To this end, we introduce an Image-to-Point (I2P) module that can reconstruct complete point clouds directly from a single RGB image, with no need for 3D inputs. Additionally, we introduce a transformer-based Point-to-Point (P2P) refinement module that uses self- and cross-attention between point tokens and image...
Fundamental Limit for One versus Two Point Sources Detection using Direct Imaging
arXiv:2606.00968v1 Announce Type: new Abstract: We consider the task of distinguishing between a single weak incoherent optical point source and two weak incoherent optical point sources located symmetrically about the first source. $\theta$ is the separation between the two point sources scaled to the Point Spread Function (PSF) width in the image plane. Using an ideal focal plane array of intensity detectors (ideal direct imaging), we quantify the performance using the Bhattacharyya...
Microcode inside the Intel 8087 floating-point chip: register exchange
In 1980, Intel introduced the 8087 floating-point chip, a co-processor that made floating-point operations up to 100 times faster. This chip was highly influential, and today most processors use the floating-point standard introduced by the 8087. The 8087 uses complicated algorithms to accurately compute functions such as square roots, tangents, and exponentials.
L-PCN: A Point Cloud Accelerator Exploiting Spatial Locality through Octree-based Islandization
arXiv:2604.10716v3 Announce Type: replace Abstract: Existing Point Cloud Networks (PCNs) have proven to achieve great success in many point cloud tasks such as object part segmentation, shape classification, and so on. The most popular point-based PCNs are usually composed of two sequential steps: Data Structuring (DS) and Feature Computation (FC). In this paper, we first describe an important characteristic of the PCN-specific DS step that has not been addressed in existing PCN...
Speeding drivers with up to 45 points on their licence still allowed on the road
Speeding drivers with up to 45 points on their licence still allowed on the road The RAC backs calls for courts to have power to order speeding offenders to have special technology fitted to their vehicles Some drivers caught speeding are still being allowed behind the wheel despite having racked up 45 points on their licence, it has emerged. Under the law, anyone who accumulates 12 or more points on their driving licence in England and Wales within a three year period - often called totting...
Accuracy-Configurable Floating-Point Multiplier Design for SRAM-Based Compute-in-Memory
arXiv:2606.08430v1 Announce Type: new Abstract: Digital Compute-in-Memory (DCiM) reduces data movement and has become a promising solution for energy-efficient edge AI. However, most existing DCiM frameworks still primarily target integer or fixed-point arithmetic, and provide limited support for compiler-integrated and accuracy-configurable floating-point computation. Directly integrating conventional IEEE 754 floating-point units into dense SRAM-based DCiM arrays, however, incurs high area...
Polynomial Invariant Generation for Floating-Point Programs
Announce Type: replace Abstract: In numeric-intensive computations, it is well known that the execution of floating-point programs is imprecise as floating-point arithmetic incurs round-off errors. Although round-off errors are small for a single floating-point operation, the aggregation of such errors may be dramatic and cause catastrophic program failures.
Aces' Wilson WNBA's fastest to 6,000 points
Las Vegas Aces center A'ja Wilson became the fastest WNBA player to reach 6,000 career points Monday in a 101-91 victory over the Seattle Storm. Wilson hit the milestone in her 278th career game and is now at 6,004 points. Former Phoenix Mercury guard Diana Taurasi, who retired after the 2024 season and is the league's all-time leading scorer at 10,646 points, reached 6,000 in 291 games.
Paving the Way for Point Cloud Video Representation Learning Using A PDE Model
Announce Type: new Abstract: Investigating spatial-temporal correlations, specifically how spatial points vary over time, is crucial for understanding point cloud videos. Traditional methods, particularly flow-based techniques, struggle with these correlations due to the unordered spatial arrangement of sequential point cloud data. To address this challenge, we propose a novel approach that regularizes spatial-temporal correlation learning by formulating the problem as a solvable Partial...
