US Patent 11068750 Testing and evaluating detection process by data augmentation

In an example, a method includes: based on a starting set of real image data of a set of one or more original images obtained using a detection process of a detection system, identifying elements of the real image data which are picture or volume elements; performing data augmentation on the identified elements to produce one or more augmented images; replacing the set of one or more original images with a set of the one or more augmented images; analyzing the set of one or more augmented images (which may be supplemented with additional real data) using the detection process; and evaluating a detection response of the detection system for each augmented image of the set of one or more augmented images. The analyzing and evaluating may be performed by using an emulator for the detection system which was used to obtain the one or more original images.
