Abstract: An image processing apparatus comprises processing circuitry configured to: acquire first image data that is representative of a subject at a first time and second image data that is representative of the subject at a second, different time; process the first image data and second image data to obtain a plurality of transformed first data sets and a plurality of transformed second data sets; transform the transformed first data sets and transformed second data sets to obtain respective first distance transforms and second distance transforms; select a combination of at least one of the first distance transforms and at least one of the second distance transforms; generate at least one morphed distance transform based on the combination; and process the at least one morphed distance transform to obtain upsampled image data that is representative of the subject at a third time.
