At one image RxC which center is (R/2 , C/2) the polar coordinations of one pixel(x,y) is:
ρ = sqrt( (x-R)^2 + (y-C/2)^2 ) and θ = tan^-1(y/x)
Τhese transformations changing not linear ρ(or/and θ) of a pixel to a new value ρ' (θ') in order the new brightness to be result of the pixel which is nearest to the new polar coordinations. This pixel is calculating with the conversion from polar to cartesian coordinates:
x' = (R/2) + ρ'cos(θ')
y' = (C/2) + ρ'sin(θ')
I want to write a function [Rho, Theta] = PolarCoord(R,C). This function is giving the polar coordinates for every pixel of an image RxC.
Secondly, i want to write a function
Iout = ImageSpecialEffect(I , Rho , Theta)
This fuction it will take for input the image I and the transformated polar coordinates of the pixels and it must giving output the distorted image.
I must apply the below tranformations to [url removed, login to view](I have sent you the transformations and the image)

Dear Sir/Madam, I am currently working in the field of Digital Image Processing and have Masters in Engineering (Gold Medalist). Kindly give me a chance to work. Thanks and With Regards, Kumar Vaibhav
I am a PhD student in applied mathematics, and have worked with Matlab for several years now. This project doesn't seem very difficult and I am confident I will complete it shortly.
