Methods of picture segmentation in recognition digital satellite images

In the article for the recognition of digital satellite images, the method of segmentation of views by thresholding was chosen. Two algorithms were used: Laplasian of Gaussian and Canny. The Laplasian of Gaussian algorithm with Gauss low-pass filter smoothes the edges and Laplace's high-pass filter sharpens the image. Based on the calculations made, clear boundaries between individual areas were obtained. The presented application in the MATLAB environment effectively detects forest areas and lakes in the satellite images.
