Claim 5:
6. A method for detecting surface characteristics of food objects, comprising the steps of:
capturing two-dimensional image data of a food object using a first imaging device and capturing three-dimensional image data of the food object using a second imaging device,
using at least one image processing unit to process either one of said 2D or said 3D image data to determine whether a potential defect is present on the surface of said incoming food object, and in case such a potential defect property is detected, determine a surface position of said potential defect and flag said potential defect for either one of said 2D or said 3D image data, and
using the at least one image processing unit to process the remaining one of said 2D or said 3D image data to determine whether an actual defect is present on the surface of said incoming food object at said determined surface position; and
in case the potential defect property is detected and no actual defect is present, indicating a false-positive result of the actual defect obtained from the 2D image data, the false-positive result being defined as a wrong indication of the actual defect on the surface of said incoming food object.
