Lenna or Lena is a standard test image widely used in the field of image processing since 1973. It is a picture of the Swedish model Lena Forsén, shot by photographer Dwight Hooker, cropped from the centerfold of the November 1972 issue of Playboy magazine.

Lena 512 png

2016-12-07 · Original_lena512.jpg ‎ (512 × 512 pixels, file size: 22 KB, MIME type: image/jpeg) Original unprocessed Lena photo. Classic photo used as a test image for image processing. We implemented the methodology on a 512 × 512 graylevel Lena image, Fig. 7-3-a.Message m is assumed to be a sequence of 32 bits. The signal W takes the form of the watermark signal corresponding to m with a constraint on the correlation properties.

For some reason, the classics tend to be 512x512 pixels in size. To make this set more generated art. Lena and Peppers are classic images; the rest are new.

The files on this page are given in lossless compression I tried the following unsuccessfully but also the names `lenna512.bmp`, `lena512.png`, `lenna512.png`, `lena.png`, `lenna.png`, `lenna.bmp` I=imread('lena512.bmp'); I know there are third-party images for the source but I would like to use the standard Matlab Lena. Lena, 24 bit color, tiff; Lena, 8 bit gray (512 x 512), raw; Lena, 8 bit gray (512 x 512), bmp; Barbara, 8 bit gray (512 x 512), raw; Barbara, 8 bit gray (512 x 512), bmp Please note that we no longer distribute the following images that were previously available in our database: 4.2.04 (lena), 4.2.02 (tiffany), elaine.512, numbers.512 and testpat.1k. Although these images have played a significant role in the history of image processing, they no longer represent the best examples for future research.

There seem to be many versions of the Lena (aka “Lenna”) test image available. This problem was noted by Shapiro in his 1993 zerotree paper, and it remains surprisingly true today. This web page is an attempt to clear up some of the confusion (and hopefully not add to it). The files on this page are given in lossless compression formats.
