Buy European@feddit.uk•Should the ESA have higher funding than NASA?English
7·7 days agoI wouldn’t mind if a serious chunk of the NATO budgets were diverted to the ESA. Even if it’s only for military purposes, it would still fund research and development that benefits the civilian sector and it would make launches cheaper because of economy of scale.

World News@lemmy.world•US intelligence says Chinese satellite imagery of bases is helping IranEnglish
2·7 days agoDLSS is essentially an advanced interpolation algorithm, it makes a guess of what should be in between two know pixel values. This can be very useful for human operators who need to look at the data. It also has the advantage that you only need a trained model and one image frame at a time. Some ‘superresolution’ methods essentially do this, but ideally you don’t use this until after you’ve applied mathematically correct techniques.
Superresolution methods exist in many forms. Basically all of them require either some prior knowlegde (or assumption) of what you’re looking at or it takes a lot of data. But once you have this, you can go beyond the optical resolution of your system in a mathematically correct way, you don’t have to guess!
Some examples:
- Lens correction: it’s possible to determine how imperfections in your lens affect the image, then correct for this. With this prior lens knowledge your images will be nearly as good as those from a theoretical perfect lens. However, you’re still limited by the (diffraction limit) laws of physics, regardless of how (im)perfect your lens is.
- Deconvolution: from physics it’s known how light diffracts (bends) and how this leads to optical limitations. Through deconvolution you can undo this. This takes a lot of guess work to find the correct solution, but once you have the solution, you can check that it’s mathematically correct (it’s a bunch of fancy integrals).
- Using information of multiple pixels v1: if an object in your image consists or more than one pixel, you have more information to determine where exactly this object is. If you know the shape of the object (e.g. a circle) you can make a fit to it and determine some properties extremely accurately (e.g. the circle center of a 1 μm particle can routinely be determined to a 10 nm resolution by a microscope that has an optical resolution of 200 nm). This method requires prior knowledge of the shape! Planes and oil storage tanks have known shapes…
- Using information of multiple pixels v2: theoretically you just need more information to go beyond the optical resolution. This can be done by taking many images (from slightly different positions?) of the same field of view. I don’t know how this works, but I have no doubt that there are people doing this.

World News@lemmy.world•‘The frontline is like Terminator’: fighting robots give Ukraine hope in war with RussiaEnglish
7·8 days agoIn my memory, which to be honest is quite limited, it was uncontroversial to say thay autonomous robots should not be used to kill people. Non-autonomous robots, such as Ukraine seems to be using, are essentially nothing more than an extension of modern arms, but one where the person ‘wielding’ the weapon is in a relatively safe place.

Proceeds to spout propaganda about the EU and against the USA, some based on incorrect numbers (e.g. minimum vacation days in NL is 20, not 27+). As much as I like the EU, this way of sharing data ain’t it for me.

World News@lemmy.world•Trump says he is ‘absolutely’ considering withdrawing US from NatoEnglish
1·11 days agoI’m pretty sure it’s not a requirement (e.g. Poland buying tanks from South Korea), but it is of course strongly incenitivised and NATO members (mainly usa) undoubtedly put pressure on other members to buy internally. The pressure will fall away and the incentives will flip around to not buying from the usa
Okay sure, having and releasing the Epstein files can be adventagious for Iran. But what I don’t see is how demanding the files would ever lead to peace. Wouldn’t it only incite Trump and co. instead of getting to a reasonable negotiating position?
