The present invention relates to a protection system for printed documents using steganographic and computer vision, materialized by the use of portable devices, where ETCODE encoded images are generated for this purpose. This method was created in order to ensure the document's authenticity, integrity of information, store information about authorship and copyright protection of printed documents. The protection method described in this patent is to generate an encoded image ETCODE using steganographic techniques, to be printed with the document, using conventional printers, and also that the decoding is performed by a digital camera portable device, obtaining therefore the information hidden in ETCODE, and then confronted with the information about the document in its digital version present in a database, thus fulfilling the proposal document protection.

A system and method for automatic tracking and decoding barcode image on the standard EAN-13 through portable, or mobile, devices makes it possible to track the barcode in any position and orientation it is in and decode it automatically in real time. To make the tracking and decoding of barcodes, methods are applied on the captured image, seeking the guidance and location of the barcode.

A system and method are capable of performing make-up virtual images obtained with portable devices with a digital camera. The method automatically detects points of interest (eyes, mouth, eyebrow, face contour) of the user's face image allowing the user to virtually apply make-up using fingers on a touch screen. Another algorithm was created to avoid 'blurring' of make-up in the application from the user's fingers. The system allows the creation of virtual make-up faces with high accuracy. To carry out the virtual make-up, methods were created for automatically detecting points of interest in the facial image and enforcing transparency in the image to simulate the make-up and restrict the make-up application area within the region where the points of interest are found. The system allows testing cosmetics application in facial images to aid choosing colors of cosmetics before actually applying them.

A method for restoring an image of a blurred barcode includes capturing the image, restoring the image by selecting one Optical Transfer Function (OTF) in a database and performing deconvolution on the image, decoding the barcode in the restored image to return numbers represented by the barcode, and displaying the returned numbers.

A method for automatic food recognition by using portable devices equipped with digital cameras. With this system, it is possible to identify a previously established food menu. To this purpose, a semi-automated method of segmentation is applied to delineate the regions in which each type of food in an image of a plate of food, captured by a user. Pattern recognition techniques are used in images, integrated into a system whose goal is to label each type of food contained in the photo of a plate of food. No type of preprocessing is performed to correct deficiencies in capturing the image, just using the auto-focus component present in the portable device to capture a clear image.
