About deinterlacing of color images

Hi, Iam using my own algorithm to find FFT and IFFT and got the result for both gray and color images.But the color images after reconstructing using my ifft algorithm giving an color image which has articrafts.I vave not interlaced while processing the i/p.But I understand that by deinterlacing we can remove articrafts in the image.So I tried to use that function.I used standard test images as i/ps.Iam new to matlab and knowing much about interlacing/deinterlacing.Plz help
