What is Gray Scale?

The amplitude of f at any point (x,y) is called gray scale or intensity or brightness of the image at that point.

For Telugu :

ఇక్కడ
amplitude అంటే విస్తారము.
intensity అంటే తీవ్రత లేక శక్తి.
ఒక image యొక్క ఏదేని ఒక point (x,y) వద్ద f యొక్క విస్తారాన్ని gray scale లేక తీవ్రత అని అంటాము.

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

Vidicon Camera Tube

Image
            A "V idicon Camera Tube"  or " Pick up Tube"  was used as a replacement of  CCD's (Charged coupled device) for converting an optical image into an electrical signal. It has an ability to store intensity information over the entire photosensitive area simultaneously on photoconductive surface. Diagram of a image dessector Parts of the Vidicon Camera Tube Cathode ray tube: It is a vacuum tube through which the beam of electrons are focused. Electrons are nothing but cathode rays. Photoconductive Target: It is a thin layer deposited on a transperent metal film. The target which is placed on the inner surface of the faceplate consists of three layers: 1) The transperent target electrode deposited directly onto the faceplate. 2) A dielectric layer. 3) A photoelectric layer facing on the electron gun that is located toward the back of the camera tube.
