Modified Laplacian Filter and Edge Detection

Image enhancement plays a vital role in image processing for long time. The authors have keen interest in underwater images as 80% of the land is filled with water and even underwater sea images needs to be preprocessed due to quality of sea water images. Due to poor visibility conditions the enviroment of world's ocean is still not properly explored.The edges of underwater images are distorted and poor image contrast is present.This book discusses combined approach of underwater image enhancement and edge detection by using modified laplacian and ACO.It also compares the previous developed approaches with the modified approach.
