Research & Papers
Visual hallucinations in MLLMs stem from feature extraction, not just language bias
Research shows multimodal LLMs hallucinate objects due to incorrect visual feature extraction and image-text misalignment, not just language priors. This challenges the dominant narrative and points to where CV practitioners should focus debugging efforts in production systems.
Read more →Autonomous driving models need affordance prediction, not just rare-object detection
CoLT-Drive reframes long-tail driving failures as decision-level affordance prediction problems rather than object recognition gaps. Directly applicable to building safer autonomous CV pipelines that must map perceptions to feasible vehicle actions.
Read more →Video moderation models miss compositional harm from benign components
MLLMs used for video moderation fail when harmful meaning emerges from relations among video components rather than explicit cues—a real deployment gap. Practitioners building video safety systems need to handle distributed implicit harm beyond per-frame analysis.

Gemini video understanding agents ship with reasoning capabilities
Google DeepMind released agentic video understanding in Gemini, enabling models to reason over video sequences and take actions based on visual content. This matters for CV practitioners building video analysis pipelines—native agent-based reasoning could replace custom post-processing logic.
Read more →HuggingFace releases 200+ WebGPU kernels for local inference
HuggingFace kernels library provides 200+ optimized WebGPU operations for running AI models locally in browsers and edge devices. Directly relevant for CV practitioners deploying models to resource-constrained environments without cloud dependencies.
Read more →BenchMIRT reveals what LLM benchmarks actually measure
Allen AI's BenchMIRT analyzes whether standard LLM benchmarks correlate with real-world performance, exposing measurement gaps. Relevant for CV practitioners evaluating vision-language models and model selection for production systems.

Real-time traffic conflict detection on edge devices
Track near-miss trajectories using Time-to-Collision (TTC) and Post-Encroachment-Time (PET) metrics in pure NumPy for edge deployment. Directly applicable to autonomous vehicle safety systems and traffic monitoring pipelines running on resource-constrained hardware.
Read more →Transformer replaces classical 3D vision pipeline
VGGT unifies camera pose estimation, depth mapping, and 3D reconstruction in a single forward pass on multi-image input. Significant architectural shift for production 3D CV systems—replaces multi-stage SLAM/MVS workflows with end-to-end learning.

Stippling photos with Python and OpenCV
Practical guide to generative art via OpenCV—converts raster images to stippled output using point-based rendering techniques. Useful for understanding image processing pipelines, sampling strategies, and output quality trade-offs at scale.
