What algorithm should be applied on above image to get that sinusoidal wave corresponding to that image?

Can you show what have you tried? And why it doesn't work?

image=imread('sine_image.jpg');
si(1,:)=image(1,:); %stores int8 value of pixel along the horizontal direction
si=double(si); %double for easy calculations
fin_si=(si-128)/128; % changes 0 to 255 values to -128 to 127 further to -1 to 1
plot(fin_si);
