Abstract: An image processing system for categorising the colour of an item is disclosed. The system comprises processing means configured to: process an image of an item to extract a portion of the image where the item is located; determine a first average colour value of a plurality of colour values associated with the portion of the image where the item is located; map the average colour value to one of a plurality of predetermined colour definitions based on a plurality of colour ranges associated with each colour definition; and categorise the colour of the item according to the mapping.

Abstract: An item classification system for use in an item handling system is disclosed. The classification system comprises processing means configured to: process an image of an item to determine one or more predetermined first item types, each first item type defined by one or more first item characteristics; process the image to determine a first probability associated with each first item type wherein each first probability is indicative of the likelihood that the item has the first characteristics defining each determined first item type; process the image to determine one or more predetermined second item types, each second item type defined by one or more second item characteristics; process the image to determine a second probability associated with each second item type wherein each second probability is indicative of the likelihood that the item has the second characteristics defining each second item type; and classify the item.

Abstract: There is provided a system and method for measuring the dimensions of an article. The system comprises a camera configured to obtain image data associated with an article, a neural network configured to identify a plurality of pixel locations in the image, and a processor configured to calculate 3D coordinates for each of the pixel locations, and further configured to determine the dimensions of the article based on the 3D coordinates.

Abstract: Aspects of the invention relate to methods of authenticating a user and user authentication systems. The method comprises classifying an image of the user as authentic or non-authentic by: identifying a separation vector between a user image characteristic vector and a hyperplane generated by a machine learning algorithm; comparing the separation vector with a threshold value; and associating the user image with a classification value if the separation vector exceeds the threshold value. The user may be authenticated based on a classification decision informed by the classification value associated with the user image.
