System to mitigate image jitter by an actuator driven camera
A device has a camera that is moveable by one or more actuators. During operation the camera moves. For example, the camera may move to follow a user as they move within the physical space. Mechanical limitations result in the camera movement exhibiting discontinuities, such as small jerks or steps from one orientation to another while panning. If the camera is acquiring video data while moving, the resulting video data may appear jittery and be unpleasant for a user to view. An offset is determined between an intended orientation of the camera at a specified time and an actual orientation of the camera at that time. A portion of raw image data acquired at the specified time is cropped using the offset to produce cropped image data that is free from jitter due to the movement discontinuities. |

Methods and system for checking ICC profile characteristics
Color conversion attempt to reproduce an input CMYK combination on a print media using an output CMYK combination. In a 2-step process, ICC profiles are used for the color conversion.

A color progression checker determines whether the 1-step process may be used for color conversions based on standard deviations of the colorants along paths within a three-dimensional look-up table for a destination ICC profile. If a certain number of standard deviations exceed 20%, then the 1-step process for color conversion may not be effective. |

Managing concurrent streaming of media streams
A system and method are provided for managing a concurrent streaming of a first media stream (031) and a second media stream (032). The media streams (031, 032) represent different recordings of an event. The concurrent streaming of the media streams (031, 032) is enabled by a resource having a resource limitation (080). To address this resource limitation, when it is determined that the resource limitation is exceeded by the concurrent streaming of the first media stream (031) streaming to a first streaming client (041) and the second media stream (032) streaming to a second streaming client (042), the first media stream (031) is selected for substituting the second media stream (032) in the streaming to the second streaming client (042). As a result of the substitution, the first and the second streaming client (041, 042) stream the same media stream rather than different media streams. This may have as advantage that the allocation of the resource is reduced, since the streaming of a same media stream to different streaming clients (041, 042) typically represents a lower resource allocation than the streaming of different media streams to different streaming clients. |

Seamless authentication for an application development platform
Various embodiments concern mechanisms for facilitating communication between network-accessible platforms for developing, hosting, or running hybrid applications that utilize resources hosted across multiple platforms. Hybrid applications cause messages or “calls” to be passed between the platforms that must be authenticated. For example, when a call is placed by a Heroku platform to a Force.com platform, the call must be authenticated for security purposes. If Heroku has not already been authenticated when the call is submitted, an authentication process is invoked. An event listener can be used to register details regarding the initial callout task, and then register or “fire” an event when the authentication process is successfully completed. Registration of the initial callout task completely separates the authentication process from the resource being invoked. Requests can be completed without requiring further user input using at least some of the details registered by the event listener. |
