Image
- 基于VC的位图图像处理程序，可实现以下功能： 1.图象参数统计：最大值，最小值，均值，直方图； 2.对比度增强：直方图均衡； 3.图象平滑：中值滤波； 4.图象锐化: Sobel算子； 5.图像旋转：将图像旋转任意角度并显示； 6.图象变换：将图象分块(8*8),作DCT变换,并作IDCT；
dct
- Dct of 4*4 matrix of an image
WatermarkingAlgorithmResearchandImplementationBas
- In this paper the watermarking programs based on the discrete cosine transform (DCT) domain DC component (DC) is adopted. Through adjusting the block DCT coefficient of the image the watermarks are hidden. And blocking the selected image accord
CadTool_ETRI_Final
- This a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN -

- 图像处理基础知识开发的这些程序源码对新手非常有帮助！4)对图像进行离散余弦变换处理（图像变换）的源源代码，编译后的可执行文件须带参数运行。dct.cpp 使用方法：dct BMP文件名 -Image processing program source code developed by the basic knowledge is very helpful for the novice! 4) the image discrete cosine transform processing (
JPEG_BaseLine_Encoder
- The JPEG compression scheme is divided into the following stages: 1. Transform the image into an optimal color space. 2. Adjust Aspect Ratio 16:9 3. Digitization Scheme 4:2:0. 4. Apply a Discrete Cosine Transform (DCT) to blocks of pixels
Jridi17.pdf.tar
- An approximate kernel for the discrete cosine transform (DCT) of length 4 is derived from the 4-point DCT defined by the High Efficiency Video Coding (HEVC) standard and used for the computation of DCT and inverse DCT (IDCT) of power-of-two lengt
MaseraConf_17.pdf.tar
- In this paper, we present area- and power-efficient architectures for the implementation of integer discrete cosine transform (DCT) of different lengths to be used in High Efficiency Video Coding (HEVC). We show that an efficient constant matrix-
