How to implement the transform in matlab given in the picture to get the output image as shown?
I tried to code but failed miserably.
I = imread('lena.jpg');
I = im2double(I);
[m n] = size(I);
J = ones(256);
alpha = 10;
beta = 10;
for i = 1 : m
for j = 1 : n
Z = (((1-beta)*5 + beta*50)*sin(alpha*180));
M = (((1-alpha)*5 + alpha*5)*sin(beta*180));
x = i + Z;
y = j + M;
J(abs(round(x))+1,abs(round(y))+1) = I(i,j);
%disp(x);
end
end
imshow(J);

I have no idea about what the values of alpha and beta doing here, I just tried to code it.
