Detection of cob and ruler after model updating the pretained maize model with different image datasets. a Updating with 10 training images from ImgCross. The original maize model detected only one cob (epoch 0). After one epoch of model updating both cobs were accurately segmented and after epoch 12 the different ruler element was detected.
