263压缩算法的雷达图像编码方案，分析了编解码算法；进行了仿真试验，在实验结果的基础上分析了编码算法压缩雷达原始视频图像的可行性和有效性。 - Jpeg , h . 261 , h . 263 and mpeg are international image coding standard , h . 263 and mpeg - 4 are two low - bit rate video coding schemes . but a jpeg based video coding scheme with mpeg - 4 is adopted and discussed particularly in this paper . how to implement the algorithm by programmable dsp chip is also presented in this paper
Jpeg 、 h . 261 、 h . 263和mpeg等国际静止和活动图像编码标准已得到越来越多的应用，其中h . 263 、 mpeg - 4是两种极低比特率的视频编码方案，而本文采用的是一种将mpeg - 4与基于jpeg的活动图像编码方案结合起来的算法，并对其进行了详细的论述。 - Furthermore , three fourier storage schemes were proposed for practical anti - counterfeiting : ( 1 ) store black - white digital images with hidden information made by image coding method , ( 2 ) store several images on the same spot with reference beams of different directions ( peristeophic multiplexing ) , ( 3 ) store a serious of given images recorded closely ( space multiplexing ) . three different fourier holograms were recorded on photoresist plates following the above three schemes using the optimized recording conditions obtained in the first part of this study work . the reconstructed images form the holograms showed some special anti - counterfeit effects
此外，本课题还研究了傅里叶全息存储在防伪上的实际应用，提出了三种防伪存储方案： ( 1 )运用图像编码方案，存储了具有隐藏信息的编码黑白二值图像； ( 2 )运用旋转复用方案，在同一存储点用不同方向的参考光存储了多幅图像； ( 3 )运用空间复用技术，在一定区域内紧靠着记录一系列特定图像的傅里叶全息图。
