Abstract: An object detection apparatus includes a boundary box decision circuit and a processing circuit. The boundary box decision circuit receives lens configuration information of a lens, and refers to the lens configuration information to determine a bounding box distribution of bounding boxes that are assigned to different detection distances with respect to the lens for detection of a target object. The processing circuit receives a captured image that is derived from an output of an image capture device using the lens, and performs object detection upon the captured image according to the bounding box distribution of the bounding boxes.

Abstract: Disclosed herein are system, method, and computer program product (computer-readable storage medium) embodiments for implementing memory management via dynamic tiering pools. An embodiment operates by initializing a first memory pool of a first tier, and invoking first and second function calls to allocate memory to the first memory pool. Responsive to these function calls, an OS may allocate differently-sized memory elements for attachment to the first memory pool, from a memory free store managed by the OS. A second memory pool, of a second tier, may be further initialized, and a third function call may be invoked, to allocate memory to the second memory pool. Here, in response to the third function call, the first memory pool may reallocate the second memory element from the first memory pool for attachment to the second memory pool.

Abstract: Correction method and device for an eye-tracker are provided. A non-predetermined scene frame is provided and analyzed to obtain a salient feature information, which is in-turn used to correct an eye-tracking operation. The correction can be done at the initial or during the wearing of an eye-tracker.

Abstract: An image operation method and system for obtaining an eye's gazing direction are provided. The method and system employ multiple extraction stages for extracting eye-tracking features. An eye frame is divided into sub-frames, which are then sequentially temporarily stored in a storage unit. Launch features of sub frames are sequentially extracted from the sub frames by a first feature extraction stage, where a data of a former sub-frame is extracted before a data of a latter sub-frame is needed to be stored. Next, the remaining feature extraction stages apply a superposition operation on the launch features to obtain terminal features, which are then computed to obtain an eye's gazing direction.

Abstract: An adaptive eye-tracking calibration method includes generating an eye model acting as a current eye model; calibrating the eye model; comparing real-time pupil data set and pupil data set of the current eye model to obtain a pupil data difference when an event happens; and generating a new eye model if the pupil data difference is greater than a predetermined threshold.

Abstract: In a dual mode eye tracking method and system, an infrared (IR) ray is emitted to perform an IR tracking mode and visible light (VL) calibration. When a first error between a VL associated gaze position and an IR associated gaze position is less than a first threshold, the IR ray is turned off to perform a VL tracking mode. In a VL checking period, when a second error between a VL associated gaze position and an IR associated gaze position is less than a second threshold, the IR ray is turned off to continue the VL tracking mode.
