Translated Title

A novel method to extract narrow water with white top-hat transform

Translated Abstract

We　proposed　a　novel　methods　to　extract　narrow　water　from　remote　sensing　image　effectively　by　enhancing　line　features　with　a　morphological　white　top-hat　transform　(WHT)　technique.This　method　obtain　line　feature　enhanced　morphological　narrow　water　index　(MNWI)　feature　image　by　doing　a　WTH　transform　on　modified　normalized　difference　water　index　(MNDWI)　image,in　order　to　further　solve　the　problems　of　narrow　water　easy　confused　with　linear　road,we　also　proposed　to　adopt　a　dualthreshold　segmentation　combined　with　an　experience　threshold　and　an　automatic　threshold　to　segment　the　small　and　narrow　water　body　from　the　background　information.The　effectiveness　of　the　proposed　method　was　validated　with　multiple　Landsat　images,and　the　results　show　that　our　method　can　not　only　extract　narrow　and　small　water　body,but　also　keep　the　continuity　of　narrow　water　effectively,and　the　extraction　accuracy　of　narrow　water　can　be　generally　over　80％.
