Abstract: An imaging sensor of an imaging reader senses return light from a target to be read by image capture along an imaging axis over a field of view that extends along mutually orthogonal, horizontal and vertical axes. Two aiming light assemblies are offset from the sensor, and direct an aiming light pattern at the target. The pattern has an aiming mark in a central area of the pattern, and a pair of aiming light lines that are collinear along the horizontal axis. The visibility of the aiming mark is enhanced by optically configuring the aiming mark to be different in brightness and/or color and/or size and/or state of existence relative to a remaining area of the pattern. The aiming mark of enhanced visibility constitutes a prominent visual indicator of a center zone of the field of view.

Abstract: A system and method of providing composite real-time dynamic imagery of a medical procedure site from multiple modalities which continuously and immediately depicts the current state and condition of the medical procedure site synchronously with respect to each modality and without undue latency is disclosed. The composite real-time dynamic imagery may be provided by spatially registering multiple real-time dynamic video streams from the multiple modalities to each other. Spatially registering the multiple real-time dynamic video streams to each other may provide a continuous and immediate depiction of the medical procedure site with an unobstructed and detailed view of a region of interest at the medical procedure site at multiple depths. A user may thereby view a single, accurate, and current composite real-time dynamic imagery of a region of interest at the medical procedure site as the user performs a medical procedure.

Abstract: Video decoding that employs motion compensated frame interpolation (MCFI) is described. The MCFI technique minimizes computations by limiting motion estimation to blocks having motion vectors that do not represent true motion. The MCFI determines these blocks using a sum of absolute differences (SAD) and a boundary absolute difference (BAD) between a current block and a previous block. The current block and previous block are obtained based on a selected interpolated block and an embedded motion vector for a block within the current frame having the same position as the selected interpolated block. If the SAD and BAD measurements do not meet certain thresholds, the embedded motion vector is classified as not representing true motion. Overlapped block bi-directional motion estimation is then performed to obtain a new motion vector. Overlapped block motion compensation is employed to generate the interpolated frame. Vector smoothing may be performed before generating the interpolated frame.

Abstract: An object in a video sequence is tracked by object masks generated for frames in the sequence. Macroblocks are motion compensated to predict the new object mask. Large differences between the next frame and the current frame detect suspect regions that may be obscured in the next frame. The motion vectors in the object are clustered using a K-means algorithm. The cluster centroid motion vectors are compared to an average motion vector of each suspect region. When the motion differences are small, the suspect region is considered part of the object and removed from the object mask as an occlusion. Large differences between the prior frame and the current frame detect suspected newly-uncovered regions. The average motion vector of each suspect region is compared to cluster centroid motion vectors. When the motion differences are small, the suspect region is added to the object mask as a disocclusion.

Abstract: A reconfigurable, three-dimensional display (1) wherein knowledge of the viewer's (4) eyes is used to enable the effective exit pupil(s) of the display system to be optimised. The system utilises this knowledge to identify contributing regions (5) within the display (1) that contribute light to the viewer (4). Priority is given to calculating and displaying the part of the display corresponding to the contributing region (5), thereby allowing the system computation requirements to be minimised. Further computation savings are achievable by recognising that only light travelling in a limited range of angles need to be considered.
