test_dct
- 2D-DCT变换是视频压缩中的常用变换[2]。在压缩过程中,将一幅图像分成许多4*4的小块进行变换。-2D-DCT transform is often used in video compression transformation [2]. In the compression process, an image is divided into many small blocks of 4* 4 transform.
dct2d
- 研究生课程 ： 来源于Xilinx公司，二维DCT变换代码。-Graduate courses: from Xilinx, 2D DCT function implementation verilog code.
dct2d
- 2D-DCT, 二维离散余弦变换模型。能够通过Synplify DSP生成Verilog代码 -2D-DCT model. This simulink model can generate RTL code via Synplify DSP.
exp10_3_BF537.7z
- ADSP-BF537 Experiment 10.3_BF537 2D DCT and IDCT using BF537 EZ-KIT
JPEG_Codec
- This a JPEG codec with AC/DC Huffman entropy coding, 4:2:0 Sampling, RGB/YCbCr converter. 2D-DCT and Quantization is included in the JPEG_Main. There also a Huffman table list in .txt, two sample testing picture and the bitrate-PSNR , Compressi
huffman coding
- 利用霍夫曼编码进行图像压缩处理，此程序为霍夫曼编码的示例(The performance of a Huffman code is a function of the entropy of the signal distribution and therefore can be highly dependent in the transform domain in which the code is applied. For example, JPEG partitions an image
JPEG lite
- 将图片分割成8*8的块然后进行DCT和量化，编码及解码(For further improvement each 8x8 block of the difference image can be transformed using a 2D DCT before quantizing and coding)
