I taught my hand gestures to run an AI coding agent
A few weekends ago I got annoyed at typing prompts into a terminal and decided the fix was, obviously, to control my AI agent with hand gestures ins…

Resolving Algorithm Output Inconsistencies When Porting Computer Vision from Python OpenCV to Niche Frameworks
Introduction Porting computer vision algorithms across frameworks—such as from Python with OpenCV to a niche image processing platform—inevitably ex…
The Critic Panel: Teaching an AI Pipeline to Check Its Own Work
Every critic in the main video-generation service's pipeline started with the same structural limit: it graded one picture. Is this frame composed c…
Three Phases of AI B-Roll: From Manual Beats to Vision-Authored Cutaways
B-roll is what makes a UGC testimonial feel edited rather than generated. The presenter talks to camera; cutaways show the product in hand, the labe…
Can AI Remember What It Sees?
So, I have been asking myself this question for quite a while, Can AI actually remember what it sees? and tell a user later that "I saw X at place Y…
Why scrolling screenshots fall apart on video feeds
I maintain a small Android app that stitches a scrolling screen into one long image. It worked well until people started pointing it at social feeds…
I built a full image editor that never uploads your photo — here's how the on-device AI parts actually work
Most background-removal and object-removal tools online work the same way: you upload an image, a server runs a model on it, you download the result…
The Matte Learns Only Inside the Band
A bad cutout rarely announces itself as a bad cutout. The car lands on a new backdrop, the paint looks clean, then a thin piece is gone. An antenna.…
Android Computer Vision for Robot Navigation
Android Computer Vision for Robot Navigation Introduction Navigation requires a robot to understand its surroundings. Cameras can provide useful vis…
Multimodal AI: how a text model learns to see
A model that only ever read text now looks at a photo of your fridge and suggests a recipe. Nothing about "predicting the next token" obviously expl…
How Two-Stage Object Detectors Went From 47 Seconds to Real-Time-Adjacent
Object detection has two broad architectural families: one-stage detectors that predict boxes and classes directly in a single pass, and two-stage d…
Stop Slouching! Build a Real-Time Spine Posture Monitor using MediaPipe and Python
We’ve all been there: hunched over a keyboard at 3 AM, neck craned forward like a turtle, debugging a race condition. "Tech neck" isn't just a meme;…
Decoupling Physical Control and Reasoning: DeepMind's Gemini Robotics 2 Architecture
Why Decouple Reasoning from Motor Control General-purpose robots have to pull off two very different jobs at once. They need to read a cluttered, fu…
Segmentation Is Not the Finish Line
A car can be cut out cleanly and still look pasted on. The outline is right. The tires touch the ground. The mirrors have no halo. The giveaway is l…
CarSegNet v2: One Lot Photo to a Showroom Composite
A buyer does not open a listing and ask what the mask IoU was. They look at the mirror stalk, the antenna, the gaps between wheel spokes, the glass,…
The Model Is the Easy Part: What a Real-Time Computer Vision Product Actually Takes
I used to think computer vision was a model problem. It is a pipeline problem, and the model is the easy part. Here is the pattern I keep seeing. A…
Identity Consistency Is the Hard Part of Two-Person Image Generation
Generating one convincing person from a reference photo is close to solved. Generating two specific people in the same frame, both still recognisabl…
I Built a Real-Time Perception Stack on CARLA. Here Is What Actually Happened.
I want to tell you about the three weeks I spent making YOLO and ROS 2 talk to each other inside a simulator, and why it was nothing like the tutori…
I Taught a Security Camera to Say "I Don't Know" — and It Got More Useful, Not Less
Somewhere around day four of building a doorbell-camera AI for a hackathon, I caught my own system lying to me. Not maliciously — it was just guessi…
Bridging the Frame Gap: Robot-Centric Pointmaps for VLA Models
What Changed In the rapidly evolving field of Vision-Language-Action (VLA) models, a fundamental architectural challenge has persisted: the frame mi…
Audio-Visual Flamingo: Advancing Open-Source Intelligence for Long-Form Video Reasoning
What Happened In a significant development for the field of artificial intelligence, researchers have unveiled Audio-Visual Flamingo (AV-Flamingo),…
A Hands-On Guide to kalbee: Your First Kalman Filter (and Beyond)
Everything you need to go from pip install to a working multi-object tracker, one runnable snippet at a time. kalbee is a Python library for state e…
Building a Real-Time Computer Vision Dashboard on the Web: The OmniVision Pro Story
Let’s face it: running computer vision models on your local machine is straightforward, but deploying them to the open web with true real-time perfo…
A Kalman Filter Is a Memory System
Three problems that look unrelated: A vibration sensor on a motor gives you a jittery reading every second. You want to know the actual wear on the…
Testing Face Embedding Nearest Neighbor Search with OpenCV SFace
Testing Face Embedding Nearest Neighbor Search with OpenCV SFace Hello, everyone. Face recognition can sound like a big topic, but technically it ca…
Vision Language Models — When AI Learns to See and Talk (Part 3 of 3)
Originally published on my blog . Cross-posted here with a canonical link. This is Part 3 of a 3-part series on the transformer revolution in vision…
What Ball Tracking Misses in Tennis Video Analysis
Most tennis video analysis starts with the ball. Where did it land? How fast did it move? Was the shot in or out? What was the trajectory? Those are…
Engineering a Cross-Platform Face Recognition Pipeline with Anti-Spoofing
I recently went down a rabbit hole after hearing how a major bank’s ATM face scanners were defeated by a literal piece of printer paper. It’s a clas…
Don't Buy It, Build It: Crafting an Open-Source, Edge-Computing AI Dashcam

Engineering a Cross-Platform Face Recognition Pipeline with Anti-Spoofing
Check out my article on this blog spot, it talks about building a face recognition system that actually works in production — not a demo, not a toy,…
