I love HDR, but until recently dynamic HDR content was hard to render in the browser. But now, with browsers shipping support for WebGPU and canvases with extended color spaces, it's actually feasible.

So what I wanted to was make an image editor capable of doing the simple edits I often need to do, but with full HDR support, which is rare in browser editors. Turning up the brightness on an HDR-capable monitor is a great way to see what your monitor can do :P

I tried to go overboard in every way I could. So brightness/saturation/hue adjustments use the okLCH color space, and there's an option to do a "content-aware resize" with seam carving, which is fast because it's parallelized using Sam Westrick's triangle-blocking algorithm [0].

Also, the site supports importing HEIC photos as taken with an iPhone, which is surprisingly hard to do correctly. Libraries like libheic don't fully support the format used by iPhones, so if used naively the HDR colors come out wrong. I'm working on a blog post about this, but the short version is that you have to use ISO 21496-1 gain map composition (which isn't even what apple documents). I'm pretty sure that pictolab is the *only* website that allows you to convert HEIC to JPEG or AVIF without messing up the HDR.

There is also a local background-removal model. Enjoy!

I shared an earlier version of this project some time ago. Since then, I have implemented quite a few changes and improvements.

The project is a cross-platform medical viewer written in C++. It also builds for the web via Emscripten/WebAssembly, so the same codebase can run both natively and in the browser.

Some of the main updates since the previous version: - Added an MPR mode. Previously, the viewer only had volume rendering; it can now display sagittal, coronal, and axial planes. - Added navigation tools for MPR views, including zoom, pan, window/center adjustment, HU probe, coordinate display, and crosshair mode. - Added measurement tools for distances and angles. - Added presets for the transfer function. - Integrated a progressive irradiance cache for the 3D rendering mode, which significantly improves performance on lower-end devices. - Added new CT and MRI datasets to the website, so it is easier to try the viewer without preparing your own data.

I am currently working on integrating a DICOM loader, so users will be able to load their own DICOM studies directly.

What do you think about the direction of the project?

This is my little app. I was sick of copying images from Pinterest and doing the posterising in photoshop when I was doing value studies as painting practice so I made a site which does the entire workflow in one bit. Happy painting!

over the last months I've experimented with many alternatives to transformers, such as one i created github repo about:

https://github.com/bggb7781-collab/lrnnsmdds

Architectures I've experimented with and my personal notes as pros and cons:

1. RNNS: Like Mamba, RWKV and my attempt above: likely the best alternative to transformers but hard to parallelize and I've personally encountered weird logical "bugs": a. Severe bias over repeated text and the ending of the text corpus (go figure...). b. Speed similar to transformers.

Pros: a. Very limited RAM utilization and very good ability to generalize and learn, perplexity reaches to extremely low levels (~1.05 for 2+ for GPT in comparison). b. Relatively easy to understand as it uses backprop, feed-forward, matrices, very similar to transformers.

2. HDC: hyperdimensional computing: for the time being mostly sci-fi...

3. SNNs: spiking neural networks - i ended up having several vibecoded implementations in C#, F#, C. Ultimately despite novel ideas, not very succesful. May be could be succesful but at the moment mostly failure...still potential.

4. TCN: temporal convolution networks...best case it seems.

pros: after than rnn/transformers, good generalization, could be the next great reduction of resources in AI-gen!
