WATER BODIES IDENTIFICATION FROM MULTISPECTRAL IMAGES USING GABOR FILTER, FCM AND CANNY EDGE DETECTION METHODS

摘要

Water bodies identification using multispectral images is a very useful application of image processing. This paper proposed a novel method for water bodies identification from multispectral images using Gabor filter, Fuzzy c-means and canny edge detection algorithm. Gabor filter is a combination of low-pass filter and bandpass filter. This two filters extracting the importance features from satellite images. From the extracted features fuzzy c-means algorithm clustered the various land use and land cover classes. Finally water bodies are identified from land use and land cover classes with the use of canny edge detection methods. The proposed approach was experimented with the use of Landsat-7, Landsat-8 satellite images. Our experimental results proved that proposed methods provides better result for water identification with high efficiency.
