DETERMINING A VOLUME SIZE OF FOOD

Abstract: in a method for determining a volumetric variable of food treated in a treatment chamber of a household cooking appliance, images are captured from the treatment chamber in chronological order. image points belonging to the food are identified in one image of a sequence of images, and a movement direction and a movement speed of the image points using an optical flow method are calculated for subsequent images. movement directions of previously identified image points are classified into classes for different movement directions and numbers of image points that fall into respective ones of the classes are counted. a variable relating to the volume of the food is counted and the household cooking appliance varies an operating parameter of the household cooking appliance influencing the treatment of the food, when the calculated variable satisfies a specified criterion.
