Embodiment Construction
[0019] The implementation of the method of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] The design concept of the present invention is: remove the influence of multiplicative noise in the SAR image through Gamma MAP filtering, improve the watershed algorithm to perform large field of view segmentation for homogenous region extraction, C-V (level set) algorithm for the extraction of dark regions in the ocean, through The visual frequency histogram removes false alarms from the extracted dark areas, and finally uses the MRF (Markov Random Field) model of contextual information to further remove false alarms from contextual information to complete oil spill detection and recognition in large fields of view of SAR remote sensing images .
[0021] Such as figure 1 As shown, a kind of SAR remote sensing image oil spill detection and identification method of the present invention, its concrete steps comprise:
