Edge detection can be said to be part of image processing, edge detection is the same as
the stages in forming the outline of a subject that appears in the image. Edge detection has
a number of other operators as follows: Sobel, Laplacian of Gaussian (LoG), and
Difference of Gaussian (DoG). Edge detection using color images is often used, but in
this case edge detection using digital images will be affected using the JPG (.*jpg)
extension. The next image is given the effect, it will be detected by the edge and then the
difference between the operators listed is seen. The results of digital images that have
effects are input into the application and then the difference can be done through edge
detection using the Sobel, Laplacian of Gaussian (LoG) and Difference of Gaussian
(DoG) operators and then the standard size used to calculate the number of each
comparison of each edge detection operator. namely MSE and PSNR. Then the edge
detection of which digital image is selected in the digital image that is given the effect is
the MSE and PSNR parameter will be seen through the three operator methods
