Image Enhancement. Takes lenna image as input, applies low pass filter, median filter, weighted and center weighted median filter. Plots the output for each image
The random walker algorithm was introduced in the paper:Leo Grady and Gareth Funka-Lea, "Multi-Label Image Segmentation for Medical Applications Based on Graph-Theoretic Electrical Potentials", in Proceedings of the 8th ECCV04, Workshop on Computer Vision
this source code based on steganography and developed in matlab. in steganography we can hide any data like images in another image.this method based on application for madical data
