:) Basicaly "optical-flow" in marketing-lingo just means it is not block-based but a dense field (vector for every single pixel)... That's why it is so slow... If you look into the papers dealing with that topic, you may find that even sparse MV-fields are called optical-flow-fields, sometimes... The techniques used are the same than in plain MV-search. You just have to apply some additional constraints which will allow the field to be more smooth and check for invalid vectors a little bit better... I personaly think it is mainly more Sound(TM) than MV-"estimation" other then that it's mainly synonymous... ;-) cu Stefan ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
