Dlib VS imgui

dlib

The apparent gender estimates from photos are using dlib, and I really ought to get what I'm doing cleaned up in such a way that other people can use it easily.

I really like dlib's code https://github.com/davisking/dlib

Additionally, C++ may be used for extremely high levels of optimization even for cloud-based ML. Dlib and Kaldi are C++ libraries used as dependencies in Python codebases for computer vision and audio processing, for example. So if your application requires you to customize any functions similar to those libraries, then you'll need C++ knowhow.

If you know C++, you don't need anything else. Go and learn APIs for C++ libraries. If you're into DSP, why not study Dlib?.

The data is mostly in this spreadsheet. The apparently facial gender estimates are made with Dlib. The mental health assessments are from Beck's Depression Inventory and the Snaith-Hamilton Pleasure Scale. The graph is made with gnuplot.

The plugin uses dlib library with a very fast HOG detector for both face recognition and detector following the relative examples.

The dlib facial recognition model thinks that I am now a distance of about 0.3 from where I started, which is far enough to start getting many false positive matches, but still within the design intent that different pictures of the same individual will be within 0.6 of each other.

Dlib's face recognition module thinks that I am about 0.25 units away from where I started; its design intent is that distinct individuals will be 0.6 or more apart, although in practice other people start showing up around 0.3.

Immediate mode is a fuzzy concept, as witnessed by this writeup: https://github.com/ocornut/imgui/wiki/About-the-IMGUI-paradi...

It's fun to see the evolution in e.g. these examples of image loading for Dear Imgui:

https://github.com/ocornut/imgui/wiki/Image-Loading-and-Disp...

DirectX9 will even load the image for you, DirectX11 okay we get a few more structures to fill out, DirectX12 is where it goes off the rails and we are filling out a bunch of UNKNOWN DONT_CARE JUST_DO_IT. Then of course Vulkan is the one that gets the big fat "this probably won't actually work for you" warning.

I understand whats happening, but you know sometimes I just want to display a fucking image.

ImGui is engine/GPU agnostic

Themeing isn't a just a retained mode thing, you can do wonders with immediate UIs, even thought (dear)ImGui doesn't provide much, you can still do wonders: https://github.com/ocornut/imgui/issues/707#issuecomment-362...

Bonus: If you want to make desktop app with UI, then this is another great C++ library and it's also simple to learn as well. https://github.com/ocornut/imgui.

AFAIK the Rust equivalent to C++'s Dear ImGui is egui.

They use a Dear ImGui, a C++ GUI library.

Aside from bugs and driver issues, Wayland has some unfortunate design limitations. For example, Dear ImGui multi-viewports don't work because "Wayland doesn't let application read or write windows positions."

This is a feature available on Windows, macOS, and of course X11. Making choices like this means desktop Linux becomes even more of a weird island that nobody wants to support.
