+ | Another of [[Randall]]'s [[:Category:Tips|Tips]], this tip claims that rotating a phone and taking a screenshot too many times will cause an image to disappear into nothingness, and warns the user against doing so. This is funny because while camera phone users are unlikely to do this, they are usually less aware of the optimal resolution for their intended purposes than they could be. A phone's "auto-rotation" feature will automatically rotate an image to the fit the phone's current orientation based on {{w|accelerometer}}s. | ||

− | The title text refers to producing photographically likely higher resolution images from lower resolutions, an active area of current research.[https://openaccess.thecvf.com/content/ICCV2021/papers/Liang_Hierarchical_Conditional_Flow_A_Unified_Framework_for_Image_Super-Resolution_and_ICCV_2021_paper.pdf] | + | The title text refers to producing photographically likely higher resolution images from lower resolutions, an active area of current research.[https://openaccess.thecvf.com/content/ICCV2021/papers/Liang_Hierarchical_Conditional_Flow_A_Unified_Framework_for_Image_Super-Resolution_and_ICCV_2021_paper.pdf] Increasingly clever ways have been developed to expand a low-resolution image into a higher-resolution ways. Taking (for example) every pixel and simply doubling its dimensions into 2x2 pixels create blocks of image that do not look any better than merely displaying the original pixel across more area. But algorithmically taking consideration of how the (original) surrounding pixels relate to each of these and smoothing the transition can often create passably interpolated variations that at least look photo-realistically plausible. But details at a sub-pixel level but that would have been significant if recorded at a greater resolution ''cannot'' emerge. |
− | + | On top of that, a single-pixel does not have any neighbours even to start the process of converting into a viable set of multiple pixels, at the next level up. That aside, there are typically only 16,777,216 possible states for a single pixel to be in (each possible level of Red, Green and Blue, assuming that Alpha-transparency is not also a component) and yet there are 79 octillion (quadrilliard, in Long Scale) possible 2x2 pixel images that could (by strict halving) have originally produced the single-pixel image. Reducing the resolution of an image is a lossy process. Upscaling back up even to that doubled resolution (quadrupled pixel-count) certainly does not guarantee that the original combination is restored. Never mind non-integer scaling factors which additionally confound the process of thoroughly rescaling away from and then back towards an original size. Results obtained through such processes will not be able to perfectly recreate the original. When scaled all the way down to one pixel, everything except a small amount of data about the image's overall color is lost, making reconstructing the original image impossible. | |
− | + | However, some output ''will'' result, and it is suggested that the upscaling algorithm will, if it fails to sufficiently restore the original image, at least give you one considered just as 'cool' as that which you no longer have. With the possible exception of it refering to the concept of {{w|color temperature}}, as generalised across an image, this seems overoptimistic if not an entirely misguided claim. | |

− | + | [A phone in portrait orientation shows an image. It is then rotated, showing the image smaller with bars in landscape orientation, then the next phone is in portrait showing the entire screen of the previous rotated sideways, shrinking it every time. The labels show the decreasing size of the original image as it goes through successive rotations.] | |
