With high spatial resolution of 250 m, MERSI images obtained from FY-3 satellite not only reveals information about the long term distribution of sea ice in large scale, but also contains informa- tion about its detailed shape characteristics, such as ice block area and roundness. Based on the spectral feature of sea ice and gray distribution feature of ice block, an integral method and process for extrac- ting the macroscopic sea ice distribution and detail ice block shape parameters was proposed in this pa- per. This method consisted of sea ice recognition, ice block detection a
