摘要:
An example apparatus is caused to receive a video sequence of a plurality of frames, and activate one of a plurality of available decoding processes based on a comparison of a size of the frames to a predefined threshold. The apparatus is also caused to select some but not all of the frames of the video sequence as potential key frames of the video sequence. The selected frames are located at or close to predefined positions along a length of the video sequence. The apparatus is also caused to decode the potential key frames according to the activated decoding process, and cause output of at least some of the potential key frames as key frames of the video sequence. The apparatus may be caused to discard from the potential key frames, one or more plain frames and/or a frame identified as being similar to other potential key frames.

An example apparatus is caused to receive a video sequence of a plurality of frames, and perform a number of operations as each of at least some of the frames is received but before all of the frames are received. The apparatus is caused to calculate a score for the frame, and compare the score for the frame to a predefined threshold. The apparatus is caused to cause output of the frame as a key frame in an instance in which the frame is received within a specified period of time and the score for the frame is above the predefined threshold. Otherwise, in an instance in which none of the scores for frames received within the specified period of time is above the predefined threshold, the apparatus is caused to cause output of one of the frames received within the specified period of time as a key frame.

Various methods for written mathematical expression analysis are provided. One method may include receiving written input where the written input is representative of a mathematical expression. The method may also include analyzing the written input to identify at least one operator and at least one operand and constructing an expression tree based at least in part on predefined symbol relationships, the at least one operator, and the at least one operand. Similar apparatuses and computer program products are also provided.

An apparatus, a method, a computer program and a graphical user interface is provided. The apparatus comprises at least one processor; and at least one memory storing computer program instructions, the at least one processor being configured to execute the computer program instructions to cause the apparatus at least to perform: controlling a display to display one or more graphical items from a first layer of a hierarchical menu system; in response to user selection of a first graphical item from the first layer of the hierarchical menu system, entering a second layer of the hierarchical menu system, wherein entering the second layer of the hierarchical menu system comprises displaying one or more further graphical items, from the second layer of the hierarchical menu system, associated with the first graphical item; detecting a change in inclination of the apparatus, while the one or more graphical items from the first layer of the hierarchical menu system are displayed on the display; and controlling, after detecting the change in inclination of the apparatus, the display to display a preview comprising the one or more further graphical items, associated with the first graphical item, from the second layer of the hierarchical menu system.

An apparatus, a method and a computer program is provided. The apparatus comprises at least one processor; and at least one memory storing computer program instructions, the at least one processor being configured to execute the computer program instructions to cause the apparatus at least to perform: processing an input pattern, detected at an instance in time by a touch sensitive display, to discriminate between a fingertip input pattern and an elongate input pattern; performing a first action after discriminating that the input pattern corresponds with the fingertip input pattern; and performing a second action after discriminating that the input pattern corresponds with the elongate input pattern, wherein the second action is different to the first action.
