[1] [2] The term downscaling usually refers to an increase in spatial resolution, but it is often also used for temporal resolution. [ 3 ] [ 4 ] This is not to be confused with image downscaling which is a process of reducing an image from a higher resolution to a lower resolution.
In the case of decreasing the pixel number (scaling down), this usually results in a visible quality loss. From the standpoint of digital signal processing, the scaling of raster graphics is a two-dimensional example of sample-rate conversion, the conversion of a discrete signal from a sampling rate (in this case, the local sampling rate) to ...

xBR ("scale by rules"), created by Hyllian, works much the same way as HQx (based on pattern recognition) and would generate the same result as HQx when given the above pattern. [15] However, it goes further than HQx by using a 2-stage set of interpolation rules, which better handle more complex patterns such as anti-aliased lines and curves.
Image resolution is the level of detail of an image. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail. Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to ...

Because those file format store the "large-scale" features first, and fine-grain details later in the file, a particular viewer displaying a small "thumbnail" or on a small screen can quickly download just enough of the image to display it in the available pixels—so one file can support many viewer resolutions, rather than having to store or ...
