What is image carving?

Image seam carving is an algorithm for content-aware image resizing invented by Shai Avidan and Ariel Shamir (http://www.faculty.idc.ac.il/arik/). The method takes content of the resized image into account and removes least significant pixels first.

Picture Resizer 3.0 uses combination of classic image resampling and image carving to change both size and aspect ratio of a picture and preserve as much of the original as possible while filling the whole destination rectangle.

Adjusting wallpapers

The need to adjust aspect ratio of wallpapers was the main motivation for the addition of the retargeting function in Picture Resizer 3.0. While digital cameras usually have a 4:3 aspect ratio, LCD displays use another ones, like 5:4, 8:5 or 16:9. PhotoResize.exe can adjust your photos for your display. Just let it know your wishes and pray.

Image aspect ratio was changed. Note that the clouds appear to have been moved rather than distorted.

How to do it

Rename the application and use the G letter in the filename before the actual resolution. Then drag and drop the photo on the tool's icon and it will adjust it for you. Here are the 4 most typical settings:

• PhotoResizeG1024x768.exe - 14", 15" displays.
• PhotoResizeG1280x1024.exe - 17", 19" displays.
• PhotoResizeG1600x1200.exe - 19" and larger displays.
• PhotoResizeG1680x1050.exe - 19" and larger displays (wide screen).

If you are not sure, what resolution is your display using, look up the display properties in Control Panel. Your internet browser states that your screen resolution is: pixels.

Unknown author (2008-05-02): Hey man, that's totally awesome. I remember seeing the POC videos of this last year and was pretty impressive if it's the same technology. Nice work on implementing it, your Picture Resizer has just increased usefulness ten-fold.

Vlasta (2008-05-02): It is similar, but adapted to be usable without an interactive user interface. Usually better than cropping when adjusting a photograph for widescreen displays.
