Abstract: A computer-implemented system and method of reproducing visual content are described. The method comprises capturing a reference image of a calibration pattern projected on a surface at an initial position and at an offset position, the offset position relating to a projection offset from the initial position by shifting the calibration pattern a predetermined amount; and determining, using the reference image, a spatial capture offset for the calibration pattern between the initial position and the offset position, the spatial capture offset measuring a spatial shift of the calibration pattern in the reference image. The method further comprises determining a scale using the spatial capture offset and the projection offset; decoding a portion of a captured image, the captured image including the visual content and the calibration pattern, to determine a position within the calibration pattern by applying the determined scale, and reproducing the visual content based on the determined position.

Abstract: A method of matching a first person in a first image to a person in a second image. At least one companion in the first image is determined and being different to the first person. A contextual confidence for the first person, the companion and each of a plurality of people in the second image is determined, the contextual confidence being a measure of prediction accuracy of a match to the first person.

Abstract: A method (300) is described of determining characteristic of an ink jet printer (15). A chart containing multiple regions or patches is printed (320) on a print medium (115) using the ink jet print (15). The chart includes at least a first region printed using a first set of nozzles, and at least a second region printed using a second set of nozzles. The first and second sets of nozzles are a predetermined distance apart in the printer head of the printer (15). The printing of the first and second regions is also separated by a print medium advance operation equal to the predetermined distance. This causes the first and second regions to be aligned in the direction of the print medium advance operation. The chart is then imaged using scanner (16) chart to form a chart image. The positions of the regions appearing in the chart image are next determined (340).

Abstract: A method of projecting a user interface for a plurality of users with a calculated orientation is provided. The method detects gestures from the plurality of users associated with a projection of the user interface and applies a weighting, representing a level of interaction between a user and the user interface, to each of the detected gestures according to a gesture type and a context of the user interface when the gesture was detected, the context including consideration of positions of the plurality of users. An orientation of the user interface is calculated based on the weighting of the detected gestures and the context of the user interface, and the user interface is projected for the plurality of users with the calculated orientation.

Abstract: Methods, apparatuses, systems and computer program products for measuring spatial characteristics of an inkjet printer are disclosed. Group of marks of a first predetermined pattern are printed on a print medium using a first group of nozzles. Groups of marks of a second predetermined pattern are printed using a second group of nozzles. A region of overlap of the printed groups of marks is formed. At least a portion of the print medium having printed groups of marks is imaged. From the region of overlap, first and second groups of marks from the first and second printed patterns are selected. For each group of marks, a position representative of that group is determined. An offset for measuring spatial characteristics of the printer between the first and second printed patterns is determined dependent upon the representative position of each of the first and second groups of marks.

Abstract: Methods (200), apparatuses (700), and computer program products are disclosed for detecting the functionality of a plurality of ink ejecting nozzles of a printing device. A test chart is printed (210) using the ink ejecting nozzles of the printing device. The test chart comprises line patterns. Each line pattern is associated with an ink ejecting nozzle and varies in one-dimension. The printed test chart is imaged (220) to generate an imaged test chart. Each line pattern in the imaged test chart is distinguishable from adjacent line patterns. The imaged test chart is analyzed (240) to determine if each of the line patterns exists at an expected location in the printed test chart. If at least one line pattern does not exist at an expected location, the ink ejecting nozzle corresponding to the line pattern that is not functioning is determined.
