Self-embedding



~~Counterfeit deterrence of sensitive or secure deocuments of value~~~
The captions (annotations) were made in a simple language, away from any technical jargon since this video was presented in the form of a demo to secondary school pupils as a motivation to pursue science fields. The video describes a special case of information hiding that is known as self-embedding. In essence, the process embeds a copy of the media into itself, of course it goes without saying that the copy has to be encrypted before the embedding takes place.

Optical Projection Tomography (OPT) showing OPT based 3D rendering of the developing pancreatic epithelium in the mouse. The projections have been generated based on the signal from E-cadherin specific antibodies and show a segment of the gut encompassing the stomach, duodenum and pancreas at embryonic day 13.5. The newly developed algorithms published in IEEE Transactions on Medical Imaging allow OPT-imaging of biomedical samples with great detail. The study was conducted in collaboration between researchers at the Centre for Genomic Regulation in Barcelona, the department of Computer Science at Umeň University, and Umeň Centre for Molecular Medicine (UCMM). The findings have important implications in interpreting the model system for the people with diabetes disease. This organ's unprecedented visualization is achieved with a set of algorithms which are fully described in the following article.
