Abstract: A method is proposed for converting an image in which each pixel takes one of two binary values, into an image in which each pixel can take continuous values. The method is iterative and works in the space domain. For each pixel, a neighborhood of the image is defined containing that pixel and other pixels. In a first iteration, the method obtains a continuous value for each pixel as a weighted sum of the binary values of the pixels in its neighborhood. In further iterations, the method obtains a continuous value for each pixel as a weighted sum of the values of the pixels in its neighborhood at the previous iteration.

The element of the macro-block header is encoded by grouping the elements of the plurality of the macro-blocks.

Abstract: A mobile device facilitates customized services for its user. For example, a mobile device can record information about a user using multiple inputs (e.g., sensors, GPS, camera, etc.). The information recorded creates a log of activities and interests of the user. One or more parts of the log are published and the user receives additional information based on the published information, such as other nearby people with similar interests or coupons. Other services of the mobile device can include biometric (e.g., facial) recognition of people, voting/polling, and language translation. The services available on a mobile device can be pre-configured so that the user can use the various services out of the box.
