@Baas - Thanks for your various pointers to the images Retargeting Seam Carving resources.

Compared to SeamCarvingGUI, I suspect DigiKam includes the more powerful "Image Retargeting" manipulation tools,
albeit at the cost of a much larger footprint :

DGK 5.30 Win-32 129 MB

SCG 1.11 Win-32 7.33MB

SCG 1.10 Win-32 4.41MB

Ditto for GIMP + LiquidRescale SeamCarving plug-in:

GIMP Portable 2.8.20

176 MB

GIMP 0.7.1 LQR plug-in

1 MB

No unfortunately these are different programs. Check out the youtube link above -- it's pretty fantastic.

webfork wrote:The Resizor program notes just resizes images and doesn't do seam carving. Here's a look at the (sadly cropped) application from the Youtube video:

I think there was some confusion as the Youtube video posted in the first reply isn't demonstrating the program the topic is about but a researcher's own implementation of a seam carving application. The Resizor mentioned in the OP actually does support seam carving, I've used it before. To enable seam carving select the 'Retarget' option in the program.

Example using Wikipedia's own test image:

Before (800px wide):



After (593px wide):



That said it's a decade old at this point and there are no doubt better implementations

VSO Seam is a free seam-carving software. It also looks portable, just extract it with Uniextract.

Update on this: PhotoDemon does something similar to Seam Carving called "Content Aware Resize"

The details are listed about halfway down the page: https://photodemon.org/2014/02/21/photo ... -live.html

An example is below, where a standard image was shrunk from top and bottom to give a more letterbox view. Unlike Resizor, this is something you can't preview. Maybe future versions will include that functionality.

Before:


After:

Update: I tested SeamCarvingGui and it works great.

Steps: Install as normal, copy files to a separate folder, install from Program Files, launch

Status: Portable (writes no settings) ... tested v.1.11 ... requires MS Visual Studio

NOTE: Unless you specify file.jpg, it will save output to BMP.
