| Abstract: | Methods and apparatuses for analyzing a sequence of images for an object
are disclosed herein. In a general embodiment, the method identifies a
region of interest in the sequence of images. The object is likely to
move within the region of interest. The method divides the region of
interest in the sequence of images into sections and calculates
signal-to-noise ratios for a section in the sections. A signal-to-noise
ratio for the section is calculated using the section in the image, a
prior section in a prior image to the image, and a subsequent section in
a subsequent image to the image. The signal-to-noise ratios are for
potential velocities of the object in the section. The method also
selects a velocity from the potential velocities for the object in the
section using a potential velocity in the potential velocities having a
highest signal-to-noise ratio in the signal-to-noise ratios. |
