Controlled Formation of Carbon Nanotubes and Nanotube Junctions from Bilayer Graphene. [PDF]

Small
Twisted bilayer graphene is cut using a scanning transmission electron microscope to create individual chiral carbon nanotubes and interconnected nanotube junctions. The sculpting is facilitated by in situ heating and automated beam control. Bilayer graphene ribbons with a width of less than approximately 4 nm spontaneously convert to CNTs, while no ...

A Machine Learning Method for Detecting the Trace of Seam Carving

Elektronika ir Elektrotechnika, 2021
Image retargeting is a manipulation approach for resizing the images while aiming to keep the image distortion at a low level. Detecting image retargeting is of importance in image forensics or sometimes of importance in checking the originality. The aim

IMGCAT: An approach to dismantle the anonymity of a source camera using correlative features and an integrated 1D convolutional neural network

Array, 2023
With the proliferation of smartphones, digital data collection has become trivial. The ability to analyze images has increased, but source authentication has stagnated.

Seam Carving based visible watermarking robust to removal attacks

Journal of King Saud University: Computer and Information Sciences, 2022
Visible watermarking offers direct copyright protection to the naked eye using visible pattern superimposed in the host image. However, due to their exposure, the watermark pattern becomes an easy target to remove by malicious entities that generates ...

Seam Carving for Image Classification Privacy

Proceedings of the 10th International Conference on Pattern Recognition Applications and Methods, 2021
The advent of storing images on cloud platforms has introduced serious privacy concerns. The images are routinely scanned by machine learning algorithms to determine the contents. Usually the scanning is for marketing purposes but more malevolent purposes include criminal activity and government surveillance.

Discontinuous seam-carving for video retargeting [PDF]

2010 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2010
We introduce a new algorithm for video retargeting that uses discontinuous seam-carving in both space and time for resizing videos. Our algorithm relies on a novel appearance-based temporal coherence formulation that allows for frame-by-frame processing and results in temporally discontinuous seams, as opposed to geometrically smooth and continuous ...
