Abstract: A method of selecting at least one video frame of a video sequence comprising a plurality of video frames. The method determines a time for analysis based on length of the video sequence and processing capability of a running device. A first sampling pattern is based on the determined time for analysis. A first set of frames in the video sequence is sampled using a first sampling pattern. The first set is sampled infrequently throughout the video sequence in accordance with the first sampling pattern. A candidate frame is determined from the sampled frames based on image quality. A second set of the frames comprising one or more of the frames in a narrow range of the video sequence near the determined candidate frame, is determined in accordance with a second sampling pattern. At least one of the video frames is selected from the sampled frames based on image quality.

Abstract: A method and system for spatially arranging a plurality of video frames for display on a layout region is provided. The plurality of video frames are selected from a video sequence based on a determination of motion of an object within the video sequence. An image layout path is determined for the selected video frames. An anchor point is determined for each selected video frame based on a determination of motion of the object depicted in the video frame, each said anchor point locating a selected video frame with respect to the layout path. The selected plurality of video frames are spatially arranged on the layout region relative to the determined image layout path and in accordance with the determined anchor points.

Abstract: A method is disclosed for laying out a plurality of containers on a page to generate a document upon insertion of content in the containers. The containers each have edges whose position upon layout is independent of the dimensions of the content inserted in each container. An association is created between an edge of a first container and an edge of a second container that is parallel and opposed to the first edge which constrains the second edge to a relation to the first edge. The page may then be laid out using the containers such that the edge of the first container moves dependent on the dimensions of content inserted in the first and second containers.

Abstract: A method of stroking a curved path with a fill of pre-determined thickness, where the path has line segments defined by a number of points, the method being performed by forming a number of projection lines normal to the curved path at the points, where each of the projection lines has a length based on the fill thickness, determining an intersection between a set of the projection lines, the intersection indicating the occurrence of a void in stroking the curved path, and then constructing one or more polygons filling in the void in the stroked path.

Abstract: Disclosed is a method of producing a cropped image from an original image for a given target crop region. The method comprising receives a plurality of example crops, each example crop corresponding to at least a part of the original image. Two example crops are selected based on at least a property of the target crop region. The method interpolates between the selected example crops to determine a crop window, crops the original image with the determined crop window to produce the cropped image.

Abstract: Disclosed are methods for laying out objects on a page which may be operative at a pre-layout calculation stage (107) or a post-layout calculation stage (109). The methods involve objects such as panels (202) into which multiple containers (203) may be configured to negotiate for space within the panel (202) upon insertion of content (204) into the panels. Typically some of the content (204) is variable for each instance of document production according to the layout. The laying out involves the application of multiple arrangement rules (FIGS. 5A-5D) and arbitration between preferred and actual dimensions (eg. height and width) of the objects including panels and containers.
