Automatic and Precise Orthorectification, Coregistration, and
Subpixel Correlation of Satellite Images, Application to Ground Deformation Measurements.
(2) For each pixel-level edge point, the Zernike moment is used to detect the
subpixel edge point (x', y').

subpixel color filter in dark state.
Next, the estimation is refined by using a
subpixel resolution algorithm in the grayscale image.
They are then refined to approach the
subpixel accuracy.
A high-speed camera captures the reflected laser line in
subpixel images, as shown in Figure 1.
First improvement would be introduction of a
subpixel detection algorithm of projectile trajectory from camera image [24].
Note that we use the parabola fit here not to obtain
subpixel disparities, but rather to reconstruct the minimum DSI value, i.e., the actual smallest matching cost in the vicinity of the sampled value.
