How to load standard image Lena?

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.

The image was originally scanned by Alexander Sawchuk at the University of Southern California. I had the pleasure of meeting him at USC once! You can find the "original" on his web page by drilling down into links on this page: http://www.cs.cmu.edu/~chuck/lennapg/

Do you propose that Matlab has no rights to include the image directly in their software? It would be so great that the standard image was built in to avoid any wrong versions of the image. - - Can you propose any standard method about how to put the image to your matlab path? Etc to access by lena.png.

[Image Analyst]

Who knows what the standard image is. It's been floating around for 40+ years and people might have changed it. I think the original one I gave you the link for is the best. Anyone using something different from that one would have to defend why they're using a modified image rather than the original. You're safest using the original.

Playboy still asserts ownership of the image as far as I know. However, use of the image is reportedly "overlooked" and by implication permitted by Playboy in scientific and education contexts, as web searches will reveal.

I=imread('lena512.bmp');

Error using imread>get_full_filename
File "lena512.bmp" does not exist.

Error in imread (line 372)
fullname = get_full_filename(filename);

figure,
imshow(I);

As you can see, that doesn't actually work.

[Image Analyst]

rgbImage = imread('Lena512.bmp');
imshow(rgbImage);

It works, however if you do it from the Answers edit box, the capitalization of the filename must match exactly.

To be clear, it doesn't matter where you do it from, MATLAB does not come with any Lena demo images. You have to go get one somewhere. There are lots of them. Whatever file you provide must be referenced using the correct spelling and capitalization, since filenames are case sensitive.
