This paper , combined with the task and based on the thorough analyses of the theories and methods of data compression , realize the data compression of the mfl inspection data using huffman coding and wavelet transform coding 本文结合课题,在对数据压缩的原理和方法进行深入分析的基础上,分别利用霍夫曼编码和小波编码等方法实现了管道漏磁检测数据的压缩。
This paper introduces the process of transform coding and the principle of still picture & moving picture compression and the standards of jpeg / mpeg - 2 and practical skill of the standards from the angle of the application and network in the development of dvd in front 本文前半部分主要从dvd的应用及未来网络化发展的角度,论述了变换编码、静止与活动图像压缩原理、 jpeg mpeg - 2标准和实用技术。
Vorbis coding algorithm can provide high quality audio compression with advanced perceptual coding and transform coding technologies ; and because of its completely open and non - patent , vobis has attracted more and more attentions by music industrial and audio users Vorbis编解码算法利用先进的感知编码和变换编码等技术提供高质量的音乐压缩,同时因为其完全开源和无专利版权费用的特点而逐渐受到音乐工业和用户的重视。
The successful application of based on this technology in block effect reduction of transform coding is also introduced in this paper . secondly , we researched the detection and recognition technology of text information in video stream , and corresponding realization method is proposed 其次,我们在视频流中文本信息的检测与识别方面开展了研究工作,并提出了相应的理论模型与实现方法,结合到实际应用系统中时,取得了良好的效果。
Nowadays , video standards were established one by one , such as the series of h . 26x and the series of mpeg . although they belong to the different organization and adopt different codec schemes , the basic theories and technologies are same , such as both of their transform code technique adopt dct 相关视频通信标准相应提出,例如h . 26x系列, mpeg系列,它们虽然属于不同标准、采用了不同技术,但他们有着相通的地方,比如它们的变换编码都采用了dct 。
Transform coding is a type of data compression for "natural" data like audio signals or photographic images. The transformation is typically lossy, resulting in a lower quality copy of the original input.
