What is the Lena image used for?
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..
What is the Lena JPEG history?
In 1973, a photo of a Swedish Playboy model named Lena (left) was used to engineer the digital image format that would become the JPEG.
Yet the model herself (right, now 67) remained mostly a mystery—until now.

Where did the Lena image come from?
A head crop of a picture of Lena S\xf6derberg, which first appeared in November 1972 in the magazine Playboy, has been consistently used as a standard picture in research papers reporting on image processing..
Who is Lena Opencv?
Lena Forsén, the real human behind the Lenna image, was first published in Playboy in 1972.
Soon after, USC engineers searching for a suitable test image for their image processing research sought inspiration from the magazine..
Why can t you use the Lena image?
However, as the user Lightness Races in Orbit pointed out, since Lenna is actually a Playboy centerfold image some people might find the usage of the image offensive, or unwelcoming to women (I don't see why women should be more offended by this than men, but let's keep that aside for now)..
Why is Lena used in image processing?
To explain why the image became a standard in the field, David C.
Munson, editor-in-chief of IEEE Transactions on Image Processing, stated that it was a good test image because of its detail, flat regions, shading, and texture.
He also noted that "the Lena image is a picture of an attractive woman..
- Authors working in nanophotonics are therefore urged to use alternative images such as 'Cameraman', 'Mandril' or 'Peppers' that have comparable if not superior scientific value.
Like the Lena image, all these alternatives are widely available. - Image processing is the process of transforming an image into a digital form and performing certain operations to get some useful information from it.
The image processing system usually treats all images as .- D signals when applying certain predetermined signal processing methods
