Motion segmentation for feature association
MetadataShow full item record
In a feature based system physical objects are represented as spatial groups of features. Systems which hope to operate on objects must make associations between features that belong on the same physical object. This paper segments interest points in individual frames of an image sequence using motion models based on image transformations. Experiments evaluate the associations made by these segments against ground truth data. We give an improved version of the existing algorithm which can lead to easier threshold selection in some systems although the ideal threshold is shown to depend on ...
