نویسندگان
چکیده
DCT transform is widely used in audio and image compression and is the basis for compression JPEG and MPEG standards. In this report, we present implementations of 8x8 2-D DCT algorithm used in JPEG standard. In section II a fast algorithm using only eleven multipliers for 1-D DCT is discussed. Then the algorithm of 2-D DCT based on 1-D DCT is derived. Section IV will demonstrate different architectural optimizations on 2-D DCT. Section V provides performance comparison among those architectural optimization techniques.

Image Compression Using Fast 2-D DCT Technique
Image Compression is a method, which reduces the size of the data to reduce the amount of space required to store the data. The Discrete cosine transform (DCT) is a method for transforms a signal or image from spatial domain to frequency component. It is a widely used technique in image compression. In this paper, we present a lossless discrete cosine transform (DCT) compression technique for t...

This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...
