摘要： Apparatus, systems and methods configured for eye tracking with slippage detection and correction are disclosed. In one example, a method comprises: obtaining a first image and a second image of a person's eye, with an imaging sensor; determining a position relationship between an eyeball center of the eye and the imaging sensor based on the first image and the second image.

摘要： In some embodiments, a method of determining encoding type and predictive mode(s) selections for a macroblock of a video frame is provided. In some embodiments, a general method 1) selects the encoding type (16×16 or 4×4) that is initially considered for a macroblock using an encoding type selection algorithm (based on an attribute of the macroblock that is easy to compute), 2) if the 16×16 encoding type is selected in step 1, consider the four 16×16 prediction modes that may be used on the macroblock using conventional methods or an improved 16×16 predictive mode search algorithm based on distortion thresholds, and 3) if the 4×4 encoding type is selected in step 1, select the 4×4 prediction mode to be used for each of the sixteen 4×4 blocks of the macroblock using conventional methods or an improved 4×4 predictive mode search algorithm based on the positional relationships between predictive modes.

摘要： System and method for integrating media objects for viewing on and manipulation via a computing device such as a personal computer. The system and method may be provided via an application program interface (API) which provides functions that allow an application program to create a scene and add media objects to the scene. The method includes preparing a translation vector and a rotation matrix for each of the media objects to define an orientation and a location of each of the media objects in the scene. The scene including the media objects is displayed. An interface is provided so that a user may manipulate the scene and the objects therein. The system and method may be implemented on a personal computer or other computing device.

摘要： System and method for processing time-based media such as sequences of images, audio sequences, and the like on a computing device such as a personal computer. A method may comprise receiving a plurality of sample data, processing the sample data based on a type of the sample data, and returning a plurality of processed sample data. The processing may include performing video compression of the sample data if the sample data is video, including identifying difficult to compress frames by determining a color frequency chart for each video frame and comparing the color frequency charts of neighboring video frames. The processing may also include performing either speech to text translation or speech compression when the sample data is voice, performing music compression when the sample data is music, and performing either text to speech translation or performing language translation if the sample data is text.

摘要： Multi-array laterolog tool systems and methods acquire a set of array measurements sufficient to provide laterolog tool measurements of differing array sizes. Such systems and method offer multiple depths of investigation while offering greater measurement stability in borehole environments having high resistivity contrasts. In at least some system embodiments, a wireline or LWD tool body has a center electrode positioned between multiple pairs of guard electrodes and a pair of return electrodes. At least some of the guard electrodes are positioned between component electrodes of associated split monitor electrodes that enable more accurate measurement of the guard electrode potential. The tool's electronics provide a current from the center electrode to the pair of return electrodes and currents from each pair of guard electrodes to the pair of return electrodes. Each of the currents may be distinguishable by frequency or distinguishable by some other means.
