摘要

•A hybrid dilated convolution spatial attention module, namely, HDCSA, is proposed.•HDCSA pays attention to the feature information of different distance scales.•A Cauchy rotation invariance loss function, namely, CRI, is proposed.•CRI constrains networks to learn rotations in skin lesion targets.
