Standard Images For Image Processing

A note on Lena | IEEE Journals & Magazine

The issues surrounding banning the use of the standard Lena image are discussed. The original Lena image was a photograph of a Swedish woman named Lena Sjooblom, which appeared in the November, 1972 issue of Playboy Magazine. The image was later digitized and became one of many possible standard images used by the image processing (IP) research community. …

Image Processing

Image processing is any form of signal processing for which the input is an image, such as a photograph or video frame; the output may be either an image or a set of characteristics or parameters related to the image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it.
