Edge Detection of Satellite Image for Water Body Identification using Marr -Hildreth Algorithm and comparing with Canny edge Detector Algorithm to Enhance Accuracy and Contrast

The aim of this research is to apply the Marr-Hildreth methodand comparing it to the Canny Edge Detector Algorithm to accurately forecast the water bodies from satellite photos. Materials And Methods Which is used to analyze a softwareundertaking by utilizing Image processing algorithms such as Marr-Hildreth and Canny edge detection. The power analysis here used 80% of the pretest power, and the sample number for the two groups is 20. The power analysis was held up with 80% and the sample amount for the two factions is 40. The Results Software effort analysis was done using Marr-Hildreth algorithm and Canny edge detector algorithm with the accuracy of 20 and 20 respectively. By using dominating samples t-tests,the statistically two-tailed significant difference in precision between the two techniques is 0.047 (p0.05).The Conclusion is thatMarr-Hildreth algorithm performs significantly better than the Canny edge detector algorithm.
