Abstract
Official abstract text for this publication.
A trajectory estimation apparatus includes: an image acceptance unit which accepts images that are temporally sequential and included in the video; a hierarchical subregion generating unit which generates subregions at hierarchical levels by performing hierarchical segmentation on each of the images accepted by the image acceptance unit such that, among subregions belonging to hierarchical levels different from each other, a spatially larger subregion includes spatially smaller subregions; and a representative trajectory estimation unit which estimates, as a representative trajectory, a trajectory, in the video, of a subregion included in a certain image, by searching for a subregion that is most similar to the subregion included in the certain image, across hierarchical levels in an image different from the certain image.
First claim
Opening claim text (preview).
What is claimed is: 1. A trajectory estimation method for estimating a trajectory of a subregion constituting all or part of a moving object in a video, said trajectory estimation method comprising: accepting images included in the video, the images being temporally sequential; generating subregions at hierarchical levels by performing hierarchical segmentation on each of the images accepted in said accepting such that a spatially larger subregion includes spatially smaller subr…
