I want to plot sine wave of pixel of image

clc
clear all
I = imread('saif1.jpg');
J = rgb2gray(I);
figure, imshow(I), figure, imshow(J);
J;
plot (J);

Saif - please clarify what you mean by the sine wave of pixel of image. I see (from your code) that you are converting an RGB image to black and white and then trying to call plot on that image. What is the intent here?

[Saif Sayed]

sir i want to convert RGB image to grey after then i want grey level of image and then want to plot the sinewave of that greylevel

[Geoff Hayes]

hmm...that doesn't really help me (probably clearer to others though). Do you have a reference (paper, site, etc.) that describes what you are trying to do?

[Saif Sayed]

sir if u dont mind can u contact me on this number 9004839946

i really need help to complete my final year project

Perhaps using fft or fft2?

I also have no idea what the sine wave of a pixel is. Please explain or give example. Otherwise I think Star Strider made a reasonable guess.
