Abstract To troubleshoot two problems arising from the segmentation of manganese
nodule images-uneven illumination and morphological defects caused by white sand
coverage, we propose, with reference to features of manganese nodules, a method called
“background gray value calculation”. As the result of the image procession with the aid
this method, the two problems above are solved eventually, together with acquisition of a
segmentable image of manganese nodules. As a result, its comparison with other
segmentation methods justifies its feasibility and stability. Judging from simulation results,
it is indicated that this method is applicable to repair the target shape in the image,… More >
