Disclosed is an imaging engine system (699) generally intended for the reproduction of graphical object images using apparatus having limited computing resources, such as so-called “thin clients”. Numerous developments of traditional image processing and rendering enable high quality image generation. One such development takes advantage of temporal coherence between one frame in an animation sequence and the succeeding frame. In particular, there will often be some edges (233, 235) of graphical objects that remain “static” across several contiguous frames. One example of this includes those edges used to draw image background detail. Another development performs antialiasing during scan line rendering of a graphic object image where sub-pixel resolution coverage bit-masks (A-buffers 29-34) are generated for a limited number of scan lines at a time. Preferably the A-buffers are generated for only one pixel at a time. Another development relates to rendering a scan line of a graphic object image in a scan line renderer for a span of pixels lying between two x-order consecutive edges intersecting the scan line. For the span of pixels, this development maintains a subset of depths present in the rendering, the subset being those depths that are present on the span and being maintained in depth order (590) and subject to removal of depths where the corresponding depth is no longer active. In another development a compositing stack (6101-6107) of image layers to be rendered in a raster scan fashion is simplified. Rendering is operable over a run of two or more pixels within which a relationship between graphical objects contributing to the layers does not change. The layers are first divided into groups (6110, 6112, 6114), with each group being separated by a layer having variable transparency (6111, 6113). For a top one of the groups, layers having constant color in the run are reduced to a single equivalent color (6115, 6116, 6117) having an associated accumulated contribution. Many other developments are disclosed.

A method of encoding an digital image (502) by a discrete wavelet transform (DWT) to a predetermined level of decomposition on a block by block basis, each block (1501, 1504, 1506) having a specified size in number of coefficients, is disclosed. The image is divided into tiles, each having dimensions required to produce the number of coefficients in a first dimension of the transformed block at the predetermined level of decomposition, and less than the number of coefficients in a second dimension of the transformed block. At a particular DWT level, tiles are decomposed. HH, HL and LH subband coefficients are accumulated to form blocks of specified size, and these are encoded to a bit stream (402). A predetermined number of associated LL subband coefficients are similarly accumulated, the process performed recursively per DWT level until the predetermined decomposition level is attained, and the corresponding LL subband coefficients encoded to the bit stream (402).

The method records a second stream of video data captured by a second camera (e.g., 104) and a second event associated with the second camera (104). A playback speed is determined based at least on a difference between a current play time position and a time position of a nearest one of the first event and the second event. The first stream and the second stream of video data are displayed in a synchronised manner. The first stream of video data and the second stream of video data are displayed at the playback speed.

A method and apparatus for tracking physical assets between a central site and other sites is disclosed. Assets are received at the central site and receive a unique identification number.

When the asset arrives at the intended destination, its entry thereto is verified and its current location updated accordingly. In addition to the location information, configuration information (e.g. software build), specific to each asset, is recorded in the database.

Disclosed herein are a computer-implemented method and a camera system for determining a current spatial representation for a detection in a current frame of an image sequence. The method derives an expected spatial representation (820) for the detection based on at least one previous frame, generates a spatial representation (810) of the detection, and extends the spatial representation (810) to obtain an extended spatial representation (830), based on the expected spatial representation (820). The method determines a similarity measure between the extended spatial representation (830) and the expected spatial representation (820), and then determines the current spatial representation for the detection to based on the similarity measure.

A method of compositing a plurality of graphic objects with a compositing buffer, is disclosed. The plurality of graphic objects forming a group is attenuated by group opacity and is composited from a top object to a bottom object. Based on a first mask and the group opacity, a second mask is generated. The first mask stores a remaining possible contribution for further graphic objects below and including the plurality of graphic objects. The plurality of graphic objects in a top down order is processed. In particular, for each graphic object of the plurality of graphic objects: (a) a contribution value for the graphic object using the second mask is determined, the contribution value representing a contribution of the graphic object to the compositing buffer; (b) a colour value of the graphic object is composited with the compositing buffer using the contribution value; and (c) the second mask is updated using the contribution value. The first mask is then updated using the second mask and the group opacity. The updated first mask is configured for further compositing of objects below the plurality of graphic objects.

Continuous stream ratio blending of two or more liquids. Each stream flow is time synchronized to all others and turned on and off to dose precise ratios into a constant pressure streams combining chamber. Combined on-off flows constitute a net flow rate exceeding some maximum continuous flow demand for the blended liquids. Dosed streams are pumped from the streams combining chamber at a rate matching their inflow, then through a mixing element into a finished blend tank. Use of a constant pressure streams combining chamber feeding a mix pump allows decoupling of individual streams ratio dosing flows and pressures one from another and from the combined stream. Blended liquid is available on demand as a continuous stream from the level controlled finished blend tank. The level sensor automatically starts and stops blended flow into the tank. Streams flow can be stopped upon completion of any dose cycle.

Disclosed herein are a method and system for classifying a detected region of change of a video frame as one of an abandoned object event and an object removal event, wherein a plurality of boundary blocks define a boundary of said region of change. For each one of a set of said boundary blocks (510), the method determines a predicted edge characteristic (520) and an observed edge characteristic (530) for said boundary block. The method then determines an individual block score (540) for said boundary block, based on said predicted edge characteristic (520) for said boundary block and said observed edge characteristic (530) for said boundary block. Once all of the set of boundary blocks have been processed, the method determines a global score (560) for said region of change, based on said individual block scores of said boundary blocks. The method then classifies the region of change (570) as an abandoned object event or an object removal event, based on how the overall score relates to a threshold.
