This video demonstrates a technique for resizing images from Dr Ariel Shamir and Shai Avidan of the Efi Arazi School of Computer Science known as Seam Carving or SIGGRAPH.
SIGGRAPH is a new method of image resizing that looks for seams of pixels with the ‘least energy’ (least contrast / change in detail) It does this both vertically and horizontally in the image and then uses this information for resizing without losing important image content. This technique can be used for reducing and enlarging images as well as removing items from the image which are not wanted (by manually painting ‘negative weight’ over an area of the image).
One thing you’ll notice in the video is that this does not look at simple columns or rows but seams of data. The good news is, you can now play with it online using your .jpg, gif and .png photos. Just head on over to rsizr and take this bad boy for a test drive.
When your done playing around, head on over to my source of the story – Lighting Mods: Seam Carving – Image resizing. A Dream that became true
