update on the fuji demosaic thing

im making progress on a good free demosaic (AHD) for fuji xtrans
Here is an initial try at the interpolation step. Each of these little subimages are results of interpolating using only sensor data from a certain direction. This is only the first part of AHD, next comes a step where at each pixel, the best one is chosen from one of these five candidate images. You notice on the NE/SW SE/NW images, different parts of the caution circle are smooth. There is a way to quantify this smoothness, and that's how you decide which image to choose each pixel from. I still have to implement that part.
After that there is a color smoothing step that I also still have to implement.
This part still needs improvement on a number of things:
> Part of the process involves a naive spatial interpolation to regularize the irregular xtrans data so that we can take an FFT. The interpolation is assumed to only add high frequency noise to the image, bit the interpolator I am using is nearest neighbor bc it's fast and easy, but in real life it adds a ton of HF noise. I should be using some kind of spline fit.
> I might be making some wrong assumptions
Already I think this is going to be worlds better than what Rawtherapee, LightZone and DarkTable already use. Even in these half-baked sample images I'm seeing none of the false color that is present in those other demosaicers.

Someone decided to buy me some gear that I could use for producing photos and videos for buidings and houses ads.
What should I ask?
I'm currently thinking into buying some SD cards, GoPro, drone, lenses, tripods, a motorized slider, and a crane, microphone, continuous lighting, and a new desktop computer.
Any tips on what brands for what kind of product?
What about "kits" of products, like a kit that has 2 lightstands, softboxes and a green backdrop?

If you have questions about a new camera, what lenses to buy and anything related to gear or wondering about getting into photography, post it in this thread.
Do not attempt to make a new thread for your new Rabal, broken glass and being new.
No pointless (brand) arguments and dickwaving allowed! You have been warned!
I repeat, ANYTHING GEAR RELATED goes in here!
And don't forget, be polite!
