摘要:
A detection apparatus, a detection method and a computer readable medium thereof for detecting an object in real time are provided. The detection apparatus is electrically connected to a video capturing apparatus for capturing a video sequence comprising the object. The detection apparatus generates a first transformed frame and a second transformed frame according to the video sequence, and retrieves a plurality of target pixel bits and a plurality of adjacent pixel bits from the first transformed frame. The detection apparatus further interlaces the target pixel bits and the adjacent pixel bits to enhance the accuracy of determining the position where the object appears in the second transformed frame without considerably increasing the computational complexity.

A playback apparatus, a playback method, and a computer program product thereof are provided. The playback apparatus is adapted to play a video dynamic image. The video dynamic image comprises a dynamic object. The dynamic object has a first selection frame, and moves with a velocity. The playback apparatus comprises a processing unit and an input unit. The processing unit is configured to expand the first selection frame to generate a second selection frame according to the velocity. The input unit is electrically connected to the processing unit and is configured to transmit a selection signal to the processing unit so that the processing unit selects the dynamic object by means of the second selection frame according to the selection signal.

A method and a system for digital image stabilization are provided for a digital image sequence. The present method calculates local motion vectors between two adjacent images by an interlaced Gray-coded bit-plane matching. An appropriate global motion vector is obtained by weighted accumulation of all local motion vectors. Finally, an accumulated motion vector is obtained by the global motion vector so as to process a motion correction on the digital image sequence and produce a stabile output image.

A system and method for object tracking path generation. The system includes a digital media player having a player interface to play a digital media file, and a tracking path processing unit. The tracking path processing unit defines and records position data of an object in frames of the digital media file on the player interface during playback. The tracking path processing unit records time data of the frames, and generates an object tracking path of the object in the digital media file according to the position and time data. Additionally, the tracking path processing unit adjusts the object tracking path when the digital media file and the object tracking path are simultaneously played in the player interface, and transforms the object tracking path to a specific format according to the position and time data.
