Claim 4:
5. The method of claim 3, further comprising:
during a training stage of the CNN, applying the mask at only an input layer of the CNN to assign the second value to pixels of the input image outside the pre-defined region;
during an inference stage of the CNN:
inputting a background input image into the CNN, all pixel intensity values of the background input image equal to the second value;
obtaining a set of background features as an output of a last convolutional layer of the CNN;
inputting a new input image into the CNN;
replacing features obtained as an output of the last convolutional layer outside the pre-defined region with corresponding features of the set of background features; and
generating an output of the CNN using the replaced weights.
