- 用于构建基于ARM平台的嵌入式系统开发平台搭建时libjpeg.so.62的产生 优化后的JIF/JPEG压缩文件解码器，减少了DCT变换的信息丢失-used to build a platform based on ARM embedded system development platform structures when libjpeg.so.6 2 production optimization of JIF / JPEG compressed file decoder, a red
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；

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 -
jpeg
- JPEG 静态图像压缩 各文件功能说明如下： 1) JPEG压缩程序：gendat.exe 2) 为压缩后的数据加上JPEG文件头的程序genjpg.exe 3) 解JEPG压缩程序extrdat.exe 其中：（1）的输入参量是需要生成的压缩文件的名字。 主程序流程为： a) 程序初始化，读取文件名称、原始图像数据等基本数据； b) 从AC.TAB和DC.TAB两个文件生成AC表和DC表，存入数组 c) 以8×8为样本单位进行DCT变换 d) 以8×8为
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
