A device and method for detecting a region of interest on a delivery object. In the method cluster identification data is stored. An item of the cluster identification data represents a cluster of image data items in a training set of image data items. A group of heat maps is stored. A heat map is associated with a cluster represented by the cluster identification data, and provides for cells of a grid a probability distribution for a probability of the cell belonging to a defined region of interest given the number of blobs in the cell. When a new image data item of the delivery object is received, the cluster identification data may be used to associate the input image data item with at least one cluster, and the heat map of the associated cluster to determine at least one region of interest in the image data item. |
