The method includes computing an image score st for the set of target views based on a number of non-occluded pixels in the set of target views, wherein the image score indicates suitability of the input image for new view synthesis in a 3D visual effect. A system and a non-transitory computer readable storage medium for performing said method for classifying an input image for new view synthesis in a 3D visual effect.

Abstract: The proposed invention aims at encoding contextual information for video analysis and understanding, by encoding spatial and temporal relationships of objects and the main agent in a scene. The main target application of the invention is human activity recognition. The encoding of such spatial and temporal relationships may be crucial to distinguish different categories of human activities and may be important to help in the discrimination of different video categories, aiming at video classification, retrieval, categorization and other video analysis applications.

Abstract: A method and system for the recognition of sensor data, like an accelerometer and a gyroscope. The method includes data/feature enrichment before a learning process. Thus, the learning process can benefit from better data, which includes both raw sensor data and enriched data/features. As a consequence, classification models may become less complex without harming accuracy and, therefore, can be more easily deployed to mobile devices, consuming less processing power and battery.

Abstract: The present invention relates to a method for compressing light-fields by exploiting their overall 4D redundancy using a hybrid approach that combines the benefits of sparse coding approach with pseudo-video sequence or multi-view coding to explore the inter-SAI redundancy and achieves very competitive results. This redundancy is particularly high when the light-fields are densely sampled. Therefore, this invention is especially efficient for densely sampled light-fields, such as the ones acquired by light-field cameras.

Abstract: Method for providing a secure mode for mobile applications including: configuring which applications should be available in secure mode; defining in the mobile operating system kernel, rules and privileges for applications defined for the secure mode; checking continuously if the secure mode is enabled by the user; if the security mode is enabled by the user, then the operating system kernel searches all processes and applications running on the operating system, suspend) the system applications not configured to be available in secure mode, hides the protected application, restricts inter-process communications and enforce privilege escalation events and enables access to application files protected by the protected application user Id; and if the security mode is disabled by the user, then the kernel releases all processes and applications that were stopped by the secure mode and denies any access to the protected application files.

Abstract: Method for updating the field of view of a graphical user interface on augmented reality through gaze gestures of a user in a certain direction using a clue component which signalizes the existence of a feature component. The method includes: as the user gazes away from a given origin-pivot graphical user interface, synchronously modifying the clue in position, scale, color and/or form; extending graphical user interface to its adjacencies by preserving spatial reference to the prior context; displaying the feature after the user gazes away from the initial position in an arbitrary angle, distance or amount; and when the user gazes back into the origin/pivot position, the feature component animates its visible state off, while the clue component performs its transformation back into the original state.

Abstract: A method for processing virtual pointer movement. The method and related components that, when active in an application or virtual environment as a whole, will aid a user in tasks that would require more effort and dexterity with currently implemented pointers. The method uses three operations (separated into two components, Smooth Pointer and Aim Assist Area) that result in a systematic asynchronous movement of a controller and its interface counterpart. Smooth Pointer, responsible for the pointer's stability, is a group of features that manage the process of smoothing the controller's rotation and final virtual pointer position by using a continuous interpolation process. Furthermore, Aim Assist Area is the component (based on two methods: Magnetism and Friction) that describes how the pointer will suffer interferences from the environment to help users have more stability while aiming at elements available in the interface.

Abstract: The present invention provides a method (200) that allows users (211) of smart appliances to interact in a similar way with objects (202, 207) such as devices, smart appliances, Web services, software applications (THINGS/objects) and people (212) and also the communication of an object (202) with another object (207). The provided method comprises mapping the entire object (207) connected as a contact. These contacts (objects) will act as real instant messaging contacts, receive user commands and entries in a natural language fashion and provide response using the IM interface. Such objects (202, 207) must register as an instant messaging user on a common instant messaging server (210). Furthermore, an application wrapper (208) is also used to map an instant messaging contact and an object allowing an object not supporting this solution to be used by a device implementing the proposed method.

Abstract: The present invention relates to a method which aims to improve data security in mobile payment transactions. To achieve this goal, we propose a highly secure method for transactions validation through video encryption and a new view of secrecy based on the combination of encrypted video (102, 203, 305) and a transparent safe card (110, 202, 307) with unique secret pattern (111, 308). This safe card (110, 202, 307) is shown as a translucent or transparent device capable of acting as “layer” or decoding mask using visual cryptography techniques. Additionally, it is proposed in one embodiment of the present invention a method for encryption of unencrypted video (602) through a frame analysis module (601) and a frame recomposition module (612).

In particular, the system of the present invention provides that the data stored in a cloud storage service are encrypted and their cryptographic keys are created from a remote device. In the context of the present invention, cloud is a set of servers that form an online service over the Internet, these servers are invisible to the user of the service pretending they form only a single server, thus forming a “cloud servers”. These keys will be divided and stored in cloud storage part and part on other devices.

Abstract: A method to allow a user, in a replacement or alternate way, to activate functions of hard keys on a device with a touch-sensitive display screen without the user touch or press the hard key, using only the device screen and a pointer device. In particular, the method executed by an exemplary system is accomplished by following the operations of accessibility, empowerment and activation of hard function keys to make accessible to the user, an icon or visual notification on a predefined display area previously mapped to that key, enable the icon during a predefined time interval when the user positions briefly a pointer device on the predefined area and activate the function of the hard key to slide the icon in a sense that the hard key would be pressed.

Abstract: 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.
