| DWPI Title: Method for analyzing sequence of images for object, involves selecting velocity from potential velocities for object in section using potential velocity in potential velocities with highest signal-to-noise ratio in signal-to-noise ratios |
| 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. |
| Use: Method for analyzing a sequence of images for an object. Uses include but are not limited to a person, a car, a lorry, an animal, an aircraft and a train. |
| Advantage: The method enables modifying an amount of resource use, reducing false positive identifications of tracks and improving tracks. The method enables using a hybrid estimate to use a spatial error estimate and a temporal error estimate to reduce pixel variation over time. |
| Novelty: The method involves calculating signal-to-noise ratios for a section in sections, where a signal-to-noise ratio for the section in the sections in an image in the sequence of images is calculated using the section in the image, a prior section in a prior image to the image in the sequence of images, and a subsequent section in a subsequent image to the image in the sequence of images. A velocity (504) is selected from potential velocities for an object in the section using the potential velocity in the potential velocities with a highest signal-to-noise ratio in the signal-to-noise ratios. |
