IMAGE MORPHING BY USING PRINCIPAL COMPONENT ANALYSIS

摘要

A method of morphing data defining an image of a first object using the morphological behaviour of a second object comprises processing a plurality of sets of data using the reference shape. Each data set defines a form of at least part of the second object and is indexed by a form reference. The data sets are processed to remove effects of size, location and rotation to define a corresponding plurality of shapes of the second object. Principal component analysis is carried out on the data sets to determine principal components and principal component scores. A form reference is received and used to look up principal components and principal component scores. A data set defining a reference shape of the first object is modified using the determined principal components and principal component scores to generate a modified data set defining a morph of the image.
