Image Compression Using Discrete Wavelet Transform And Discrete Cosine Transform
نویسنده
چکیده
The area of digital image processing has witness a great deal of development during the past few decades. Image compression is one of most important aspects of the fields. The paper presents simple and efficient algorithm for compressing image data, the algorithm involved using the glory wavelet transform technique, which was the most usable method for varied image processing field due to its results and properties. The next step is to ignore the less affected element and adopt the high impact elements, where they could be handle using adaptive Discrete Cosine Transform (DCT) method within the whole steps for JPEG image compressing strategy. Excellent results have been obtained depending upon two main criteria check; the compression ratio, and the reconstructed image quality (through PSNR criteria).

This paper proposes new image compression technique that uses Real Fourier Transform. Discrete Fourier Transform (DFT) contains complex exponentials. It contains both cosine and sine functions. It gives complex values in the output of Fourier Transform. To avoid these complex values in the output, complex terms in Fourier Transform are eliminated. This can be done by using coefficients of Discr...
