Abstract: A method of determining a measure of gaping in a fish fillet item, involves the steps of obtaining three-dimensional profile data of a first area of the fish fillet item, obtaining optical imaging data of a second area of the fish fillet item, wherein the first area and the second area are overlapping at least within an overlap area; and determining the measure of gaping in the fish fillet item based on the three-dimensional profile data within the overlap area and the optical imaging data within the overlap area.

Abstract: A method and a system for determining a weight estimate of food items include receiving an image of an outer surface of a food item. The image having a plurality of pixels each having a measure. By the measure of the pixels, a surface content of a first tissue which is distinct from a second tissue is identified. The surface content is translated into a volume content and a density parameter is recorded. An estimate of the weight is determined based on the volume content, the density parameter, and volume data identifying the volume of the food item.

Abstract: A method and a system for automatically tracking a food item in a processing facility involves a food item that is received in a check-in position where a check-in image is captured, and a unique identification insignia, UII is generated based on the check-in image. The food item is handled and moved to a check-out position where a check-out image is captured. To facilitate automatic tracking of the food items, a recognition process is carried out to establish if a check-out image can be assigned to the created UII, and a data-record is, in that case, generated with the recognized UII.
