The multispectral images of SPOT 6 are employed to demonstrate the effectiveness of the CCNet.The multispectral images cover 5 different bands in the visible，near infrared range.The detailed band information is listed in Table 3.We obtain 1 000 multispectral images with the size of 1 024×1 024 in different illumination and weather conditions，such as weak contrast condition，strong reflective condition，cloud-covered condition，or strong wave condition.The RGB and NIR images are rescaled 4 times to achieve the same resolution of the panchromatic（Pan.）images.These images are divided by 4:1 as the training and test samples.The training and test samples contain 3 132 ships and 756 ships respectively whose lengths vary from 15 pixels to 305 pixels.
