Abstract

Keksinnön kohteena on menetelmä, joka käsittää kuvan referenssialueen määrittelyn, kuvan kohdealueen määrittelyn, referenssialueen liikekenttätiedon saamisen sekä indikaation sisällyttämisen bittivirtaan siitä, että kuvan referenssialueen liikevektorikenttä on liikevektoriennustamisen lähteenä kuvan kohdealuetta varten. Keksinnön kohteena on myös menetelmä, joka käsittää tiedon dekoodauksen siitä, että kuvan referenssialueen liikevektorikenttä on liikevektoriennustamisen lähteenä kuvan kohdealuetta varten, kuvan referenssialueen dekoodauksen sekä kuvan kohdealueen dekoodauksen.
