A CenterNet++ model for ship detection in SAR images

Pattern Recognition, 2021
Ship detection in SAR images is a challenging task due to two difficulties. (1) Because of the long observation distance, ships in SAR images are small with low resolution, leading to high false negative.

Arbitrary-Direction SAR Ship Detection Method for Multiscale Imbalance

IEEE Transactions on Geoscience and Remote Sensing
The arbitrary-oriented ship detection in synthetic aperture radar (SAR) imagery remains especially challenging due to multiscale imbalance and the characteristics of SAR imaging, a problem that is more pronounced than in optical ship detection.

Ships ahoy

The International Journal of Biochemistry & Cell Biology, 1999
In 1996 three groups independently cloned a hemopoietic specific, src homology 2-containing inositol 5'-phosphatase which, based on its structure, was called SHIP. More recently, a second more widely expressed SHIP-like protein has been cloned and called SHIP2.
