What is an Image?

Image may be defined as 2-dimensional intensity function f(x,y) where x,y are the spatial coordinates.
For telugu people:

Intensity:   తీవ్రత, శక్తీ

x,y అనే ఈ coordinates కి రేంజ్ మనం తీసుకున్న ఇమేజ్ బట్టి వుంటుంది. ఉదాహరణకి మనం కానీ 160 x 160 రిసోల్యుషన్ తో వున్నా బొమ్మని కానీ తీసుకుంటే అప్పుడు x, y రేంజ్ 160 మరియు 160 గా వుంటుంది.

Matlab code to get negative of an image

Image
clear all; clc; close all; OriImg=imread('lena.tif'); %This will reads the image to i NegImg=imcomplement(OriImg); %This will moves complement of image i into y %The below statements will produce the output subplot(1,2,1);imshow(OriImg);title('Original image'); subplot(1,2,2);imshow(NegImg);title('Negative image'); RESULT:

To find the MSE value

%Let me explain with the same example. %To the input image Iimg applied the 'Salt & Pepper noise' with the noise ratio of 20% and named as 'Nimg'. %Now for the 'Nimg' i applied median filter and named as Mimg. %Now i need to find the 'Mean Square Error' MSE comparison between Mimg and Nimg. clear all close all clc; Iimg=imread('moon.tif'); [r c]=size(  Iimg ); d=ndims( Iimg ); if d == 3      Iimg =rgb2gray( Iimg ); end Iimg=double( Iimg ); Iimg= Iimg /225; Nimg=imnoise( Iimg ,'salt & pepper',0.2); Mimg=medfilt2( Nimg ,[5 5]); clc; Diff= Nimg - Mimg ; MSE= sum(sum(Diff.* Diff)) / (r * c); fprintf('\n\nThe Mse value is:  %d',MSE1); subplot(1,2,1);imshow( Nimg );title('Noised image'); subplot(1,2,2);imshow( Mimg );title('Denoised image'); RESULT: The Mse value is:  2.521604e-002 i.e, MSE ~ 0.0252

Example for simple function with two parameters in matlab

%Let us discuss the function with two paramaters with simple example %We know the formula for the volume of a cone is p*(1/3)*r^2*h conevolmain.m clc; clear all; radius = input('Enter the radus of the cone:'); height = input('Enter the height of the cone:'); cv=conevol(radius,height); fprintf('Volume of the cone with radius %.1f \n and with height %.1f', radius,height); fprintf('\n is:  %.2f'\n,cv); conevol.m function out=conevol(radius,height) out=(pi/3)*radius^2*height; end output: Enter the radus of the cone:5.6 Enter the height of the cone:6 Volume of the cone with radius 5.6  and with height 6.0  is:  197.04
