But anyone who studies digital image processing has used the standard test image Lenna.

do you know who she is?

Her full name is Lena? Soderberg? Is Raina playing? Boys' spelling, and Lena? This is Swedish spelling.

The source of this image:

1973 in June and July, Alexandria? Sochuk, is that SIPI? The teaching assistant of the Department of Electrical Engineering, together with a graduate student and SIPI's laboratory director, is eager to find images for the conference papers in the laboratory. They are tired of those boring test images in stock, and they need an image of a face.

Just then, a man was holding a new play? The boy came in.

Their engineer took the magazine and left the middle naked? Body? The top of the insert 1/3 was torn off, hehe, just enough to roll on the copy roller of the multi-head scanner ... so this classic 5 12X5 12 was born. I have always wondered why everyone chose this beautiful photo for testing and analysis. Is there anything special? Who is the mysterious Lenna? I didn't find the answer until yesterday. The photo of beauty Lenna comes from a famous drama? Boys magazine. 1973 in June, an assistant professor at the Institute of Signal and Image Processing of the University of Southern California and one of his graduate students planned to find a digital photo for an academic conference, but they were bored with the piles of "boring" photos at hand. In fact, what they need is a face photo, which can make people shine at the same time. At this moment, someone just walked into the lab with a copy of the game? Boys magazine, the story happened ..... and due to the need of laboratory equipment and test pictures at that time, lenna's picture just scratched the shoulder of the original picture.

Since then, this photo has been widely used. Nice play? Lenna, a boy and a girl, is famous in the field of computer vision and was invited as a guest to attend the 50th anniversary academic conference of digital image science and technology. At the meeting, Lenna became one of the most popular people. She made a brief self-introduction and was asked for autographs by countless fans. The origin of Lena standard test image Lena diagram is well known in the study and research of digital image processing, and is often used as an example of various experiments of digital image processing.

The picture was originally published in the first issue of 1972. 1 1 Play? Part of a nude illustration photo in Boy magazine, this issue of Play? Boys are also the best-selling issue over the years, with sales of 7 16 1 and 56 1. 1973 in June, an assistant professor at the Institute of Signal and Image Processing of the University of Southern California and one of his graduate students planned to find a digital photo for an academic conference, but they were bored with the piles of "boring" photos on their hands. In fact, what they need is a face photo, which can make people shine at the same time. At this moment, someone just walked into the lab with a copy of the game? Boys' magazine, as a result, the story happened ... but because of the need of laboratory equipment and test pictures at that time, lenna's picture only scratched the shoulder of the original picture.

The picture shows a Swedish model? Lena. Soderberg? (ne？ Sj & ampouml& ampoumlblom). The English cultural name "Lenna" which is widely used now was originally created by Play? Boy magazine named this photo when it was published, so that English readers can read the pronunciation of "Lena" in Swedish roughly correctly. Lena. Soderberg? Ms. Li still lives in her hometown of Sweden, has a family of three children and works in the State Liquor Monopoly Bureau. 1988 She was interviewed by some computer-related publishing houses in Sweden. In the photo, she was very surprised and excited about such an adventure. This is the first time she learned that her photos were used in the computer industry. Lena. Soderberg was invited as a guest to attend the 50th anniversary academic conference of 1997 digital image science and technology. At the meeting, Lenna became one of the most popular people. She made a brief self-introduction and was asked for autographs by countless fans.

Lena diagram is the most widely used standard test diagram in image compression algorithm-her face and bare shoulders have become the de facto industrial standard. However, the use of this image has also caused some controversy. Some people worry about its pornographic content; Play? Boy magazine threatened to sue Lei Natuo for unauthorized use. However, the magazine has given up this threat and encouraged the use of Lei Natuo in the public interest.

David C. Monson (David? C.Munson), IEEE Transactions on Image Processing (IEEE? Deal? Open? Image? Processing editor)? In the months of 1996 and 1, two reasons were cited to explain the popularity of Lena diagram in scientific research: 1. This image is moderately mixed with details, smooth areas, shadows and textures, so that various image processing algorithms can be well tested. 2.Lenna is a beautiful woman. For researchers (mostly men) in the field of image processing, Meitu can effectively attract them to do research.

Here, as a researcher (male) in the field of image processing, I pay tribute to lenna ~ ~!
