[AllUsers-ISR] Seminário amanhã às 11h

[Nuno Gonçalves]

Olá, boa tarde 

 

Amanhã vamos organizar um seminário no anfiteatro do ISR, às 11h, sobre uma técnica que desenvolvemos para um dos projetos com a INCM, que mereceu já um pedido provisório de patente, e que apresentaremos no Eurographics 2018, daqui a 2 semanas.

Os dados do seminário em baixo.

Convidamos todos e todas a estar presentes.

Título: Halftone Pattern: A New Steganographic Approach

Resumo:
In general, an image is worth a thousand words, but sometimes, words are the most efficient tool to communicate some information. Thereupon, in this work, we will present an approach for combining the visual appeal of images with the communication power of words. Our method is a steganographic technique to hide a textual information into an image. It is inspired by the use of dithering to create halftone images. It begins from a base image and creates the coded image by associating each base image pixel to a set of two-colors pixels (halftone) forming an appropriate pattern. The coded image is a machine readable information, with good aesthetic, secure and containing data redundancy and compression. Thus, it can be used in a variety of applications.

 

This research has been developed in collaboration with Bruno Patrão and Nuno Gonçalves in the TrustStamp project, and will be presented at EUROGRAPHICS 2018.

 

 

Cumprimentos,

Nuno Gonçalves.
