The basic algorithm framework used for head tracking was based on a gradient and color-based tracker [13] with additional tweaks.
Since Gallup's approval rating tracking is based on a three-day average, whereas its horse-race polling is based on a seven-day average, the approval numbers can sometimes be a leading indicator for where their horse-race numbers will go.
Vehicle tracking is based on matching by normalized cross correlation (e.g. [13]).
Tracking is based on detected faces in the Hue Saturation Value (HSV) color space.
Marker tracking is based on coded markers that can be configured to an arbitrary number and size.
The tracking is based on the automated method described in Ikegawa and Horinouchi (2016) and Horinouchi et al. (2017a).
The tracking is based on quadrature PLL without using VCO, DAC, counter and look-up tables (LUT).
A more advanced approach for skeletal tracking is based on image registration between recorded X-ray images and backprojected CT scans [3, 18, 19].
In Fig. 24, target is a vehicle that tracking is based on the area which has a distinct color from background.
Positioning tracking is based on two technologies: Wi-Fi fingerprints, created using existing networking infrastructure and Bluetooth beacons installed at testing locations.
(v) Close-in echoes: tracking of closely spaced signals with the proper multiple path signal model may lead to increased mean square errors compared to the case when tracking is based on a single-path model [29].
