Optical Remote Sensing Ship Detection Combining Channel Shuffling and Bilinear Interpolation
Remote SensingMaritime remote sensing ship detection has long been plagued by two major issues: the failure of geometric priors due to the extreme length-to-width ratio of ships; and the sharp drop in edge signal-to-noise ratio caused by the overlapping chromaticity ...
