Editing Lossy compression (section)

== Lowering resolution ==
A general kind of lossy compression is to lower the resolution of an image, as in [[image scaling]], particularly [[Decimation (signal processing)|decimation]]. One may also remove less "lower information" parts of an image, such as by [[seam carving]]. Many media transforms, such as [[Gaussian blur]], are, like lossy compression, irreversible: the original signal cannot be reconstructed from the transformed signal. However, in general these will have the same size as the original, and are not a form of compression. Lowering resolution has practical uses, as the [[NASA]] [[New Horizons]] craft transmitted [[thumbnail]]s of its encounter with Pluto-Charon before it sent the higher resolution images. Another solution for slow connections is the usage of [[Interlacing (bitmaps)|Image interlacing]] which progressively defines the image. Thus a partial transmission is enough to preview the final image, in a lower resolution version, without creating a scaled and a full version too.{{citation needed|date=November 2019}}
