PHaker News - A Stupid Markov Chain Experiment

I've been learning all about autostereograms (aka "Magic eye" illusions) recently and had a fun idea: If I can somehow get a depth image of my webcam, I can see myself in a "magic (eye) mirror" on my screen. It turns out that it's actually pretty feasible to get real-time depth estimates, at least on newer hardware and in browsers with WebGPU. To my delight, this worked pretty well, so I decided to polish it somewhat and share it here. To be honest, all the heavy lifting is done by the depth-estimation model [1], otherwise this demo just wouldn't be possible. I will warn you that viewing…

In plain words

PHaker News is a web-based "magic eye" mirror that uses real-time depth estimation from your webcam to create autostereogram illusions of yourself on screen. Built with WebGPU technology, it leverages a depth-estimation model to generate the 3D effect. The project is designed for users interested in autostereograms and visual illusions, though it requires a modern browser like Chromium and performs best on desktop or laptop hardware. Viewers should note that autostereogram viewing requires practice to perceive the effect properly.

    I forked a PyTorch DeepDream implementation and added video support with temporal consistency. It produces smooth DeepDream videos with minimal flickering, and is highly flexible including many parameters and supports multiple pretrained image classifiers including GoogLeNet. Check out the repo for sample videos! Features: - Optical flow warps previous hallucinations into the current frame - Occlusion masking prevents ghosting and hallucination transfer when objects move - Advanced parameters (layers, octaves, iterations) still work - Works on GPU, CPU, and Apple Silicon
