Methods and integrated systems for camera motion analysis and moving object analysis and methods of extracting semantics mainly from camera motion parameters in videos and video segments without shot changes are described. Typical examples of such videos are a home video taken by a digital camera and a segment, or clip, of a professional video or film. The extracted semantics can be directly used in a number of video/image understanding and management applications, such as annotation, browsing, editing, frame enhancement, key-frame extraction, panorama generation, printing, retrieval, summarization. Automatic methods of detecting and tracking moving objects that do not rely on a priori knowledge of the objects are also described. The methods can be executed in real time.

A solenoid valve assembly includes an armature having a longitudinal axis and an ovular cross-section, the armature being moveable along the longitudinal axis from a first position to a second position, and a bobbin including a solenoid coil configured to electromagnetically move the armature when energized. The bobbin defines a recess also having an ovular cross section for receiving the armature and restricting lateral movement of the armature, thereby providing a linear actuation path for the armature along the longitudinal axis. A flux coupler and a flux bracket form a magnetic circuit with the bobbin to electromagnetically move the armature. The flux bracket has a pole piece with a commensurate ovular cross-section that limits the movement of the armature along the longitudinal axis, thereby determining a stroke length of the armature. During manufacture, the flux bracket, and therefore the pole piece, are moved relative to the flux coupler to set the stroke length.
