SHIFT VECTOR RELIABILITY DETERMINING APPARATUS AND METHOD
First Claim
1. An apparatus for determining the reliability of shift vectors between two images comprising:
- an image compensation unit configured to compensate local shifts between a first image and a second image and to obtain a compensated second image,a similarity estimation device configured to determine a similarity information by determining one or more similarity measures between said first image and said compensated second image,a vector consistency check device configured to compare shift vectors describing the shift between said first image and said second image from different shift estimation directions to obtain a consistency weight information, anda combination unit configured to combine said similarity information (2) and said consistency weight information to obtain a reliability information describing the reliability of said shift vectors.

Abstract
An apparatus for determining the reliability of shift vectors between two images comprises an image compensation unit for compensating local shifts between a first image and a second image and to obtain a compensated second image. A similarity estimation unit is provided for determining a similarity information by determining one or more similarity measures between said first image and said compensated second image. A vector consistency check device for comparing shift vectors describing the shift between said first image and said second image from different shift estimation directions to obtain a consistency weight information, and a combination unit for combining said similarity information and said consistency weight information to obtain a reliability information describing the reliability of said shift vectors are provided.
