DESCRIZIONE
This invention relates to a food processing apparatus ( 1000 ) for detecting and cutting tough tissues from food item pieces such as fish or meat fillets or poultry items. At least one x-ray machine ( 1 ) is associated to a first conveyor ( 2 ) for imaging incoming food items conveyed on the first conveyor and based on the imaging generating x - ray image data indicating the location of the tough tissues in the food item pieces. A vision system ( 3 ) supplies second image data of the food item pieces subsequent to the imaging by the at least one x-ray machine. The second image data including position related data indicating the position of the food item pieces on the second conveyor prior to the cutting. A mapping mechanism including a processor determines an estimated coordinate position of the food item pieces on the second conveyor ( 6 ) by utilizing the x-ray image data and tracking position data from the tracking mechanism. The processor compares the estimated coordinate position of the food item pieces to the actual position on the second conveyor based on the second image data.
