Short answer: you can obtain some very good results, but only under certain conditions and absolutely not even close to what is shown in the linked video clip. My company, Amped Software, develops image and video processing software for forensic and intelligence applications, so basically we are the real world counterpart of the CSI software. With ...


The process is complicated but this should give an intuition into what's going on. Imagine you have a regular camera, but with motors to move the sensor half a pixel in any direction. Instead of taking one image this camera takes four: one centred, one shifted half a pixel right, one shifted half a pixel down, and one shifted half a pixel right and half a ...


You can't make something out of nothing, you have to have (or guess) some information in order to be able to enhance an image in any way. For example if you know the properties of the blurring function (and there is no image noise) then you can actually unblur a photo. However you rarely know the blur function and noise is always present so that severely ...


you can check out: and the product:


Absolutely. This is called "superresolution", and we actually have a number of questions and answers on it in the superresolution tag. There is also a wikipedia article where you can learn more.


Consider that the sensor is not a perfect capture device. Each pixel will be recorded with some amount of error. For example, if the most accurate value of a pixel is N, the sensor will record a value that is in a range N-E to N+E for a given E. For a good sensor E is small, a bad sensor will have a larger E. Also note that on each exposure a given pixel ...


There is some commercially available software out there, with Super Resolution. I haven't tried any of these myself, but the advertising material is pretty good. The software is pitched towards surveillance, security and armed forces but I guess some forensic units will have access to this stuff. Two examples are: Ikena from MotionDSP and TacitView from 2d3 ...


Superresolution techniques require pretty good source data to start with, and that source data usually needs slight offsets between each frame (dithering.) Without a tracking mount, you will see field rotation in the corners of the frames, and that will greatly diminish your ability to align and stack, let alone apply superresolution. Distortion mapping can ...


My own experience with doing similar things would suggests that you should take all the pictures you need to take in one go using a using a tripod (note that tripods are cheap). The workflow for the projects I've done looks as follows. You take pictures with a tripod and remote control at the lowest ISO setting available. You should use manual focus and ...


This is a partial answer. For a 36"x24" poster the 5400 x 3600 px size is OK: You have a 150 ppi file which is good. You can probably go to 200 ppi (7200 x 4800px), but the difference is not very noticeable, even using a magnifier. In my opinion you don't need 300 ppi at all. The main point for those resolutions are the printer resolution and smoothness. ...


The following is as I understand things. People should feel free to point out any misconceptions so that we are all edified, but hopefully will actually point out any they spot and not just mumble in their beer. (or beards or ...). Put simply and simplistsically, there is slightly different information in the different photos and various methods are used ...


This plugin for ImageJ will perform super-resolution processing but only for black-and-white images. I haven't used it myself though.


Image/video enhancing to the level suggested in TV shows is simply not possible, and is actually limited by the image capturing device. That's the technology that would need to evolve first. It is impossible to gain information from a collection of 10 pixels into a recognisable object. At the pixel level, that's the final amount of information provided in ...
