Neat algorithm; good to see it proposed for merging into scikit-image
From 1 comment
It is a neat algorithm, hope you are able to get it merged into scikit-image [0] without too much fuss~ good luck! [0] https://github.com/scikit-image/scikit-image/issues/3082

Seam carving is cool, including for image fingerprinting
From 1 comment
Seam carving is really cool, not just for the typical application of changing images, but also as a method of fingerprinting images (and the other side, anonymizing them). There…

Too slow: 14 seconds per image
From 1 comment
14 sec per image is excessive, is there either an implementation or algorithm that can handle do this in less than 500ms per image?

Photoshop Content Aware Scaling is much faster
From 1 comment
For anyone interested, Photoshop has had this feature for a long time - Content Aware Scaling. It's also much faster.

Try a CNN or ML-based energy function

xg15 on HNThe biggest value of ML here would likely be to create a more useful energy function. This could be informed either by object detection data or hand drawn "energy" masks. The…

skimage.transform.seam_carve
From 1 comment
It's 14 seconds to remove 200 seams on the 512-by-342 bench image, but I note potential optimizations in the notebook. Right now, the seam_carve function in scikit-image accepts…
