In this paper we are discussing the Fourier transform technique for image transformation and compression. Here, we are presenting the implementation technique for image compression by using the Fourier transform method and analyzing the performance. We are also observing the results after transformation of image with quantization process. The quality of the reconstructed compressed image is also analyzed after applying the de-quantization method. The analysis of image quality is performed by using mean square of error and peak signal noise ratio. The results are showing that it is possible to achieve maximum PSNR value.

Keywords: Fast Fourier Transformation, Image compression, Image transformation, Quantization.
