A food product checking system for at least one of identification and grading of food products packed in a tray is provided, comprising a tray positioning area, an illumination device for illuminating the food product with white light, at least one camera for taking images of the illuminated food product, and an evaluation device for image processing of taken images, wherein the evaluation device is adapted to perform a color analysis of taken images.

Food product checking system and method for identifying and grading food products

An x-ray system and method capable of producing very accurate RTR images corrected for x-ray system inhomogeneities. A three-dimensional correction memory is used to store deviation information relating to system inhomogeneities. The three-dimensional correction memory is indexed by x and y coordinates of the image plane and an attenuation coordinate associated with a plurality of standard samples. The standard samples are exposed in turn, and deviations between the measured attenuation and the nominal attenuation are noted and stored at the x and y coordinates in the attenuation plane for the sample then exposed. The procedure is repeated for a plurality of samples to create a three-dimensional correction array. An object to be imaged creates a set of raw intensity information. The raw information is corrected by accessing the correction memory at the x and y coordinates of each pixel to be corrected and the attenuation coordinate associated with the raw measurement. The deviation information is applied to the raw measurement to produce and store a corrected attenuation factor for each pixel.
