- We also derived the relationship between the radial local density distribution and the observed line integral density distribution by fourier integral transform . on this basis , the density inversion calculation is realized through fft method and is independent of abel inversion
另外,本文还着重推导了线积分密度分布和径向体密度分布之间的傅立叶积分变换关系,并利用快速傅立叶变换实现了完全抛开abel反演公式的密度反演计算。 - Firstly , we introduce the development of image compression , the method of image compression , the metewand of image compression performance and the international standard of image compression . otherwise , we fully discuss and analyze the theory of wavelet transform , and study the approach of image coding through wavelet transform
本文首先对图像压缩编码的发展、图像编码的主要方法、图像编码性能的评价标准以及目前图像编码的国际标准进行了介绍,并对小波变换理论进行了比较全面的阐述,在此基础上探讨了小波变换实现图像数据压缩时的一般步骤。 - Secondly , based on the above method , this paper presents another new method for color image compression coding by using correlation of color components combined with wavelet transform . in this method , one of the three color components of a color image is coded using wavelet transform zerotree coding , and the component is segmented into several non - overlapping subregions of the same size . based on the calculated correlation coefficients between the component and the other two components in the same subregion , the coding for the other two components becomes the coding of correlation coefficients
其二在上面这种方法的基础上,又提出了利用色彩分量相关性结合小波变换实现对彩色图象的压缩编码,该方法同样是对彩色图象三个色彩分量之一进行小波变换零树编码,将该色彩分量分割成若干个大小相等不重叠的子块,计算出该色彩分量在每个子块中与另两个色彩分量在同一子块的相关系数,由此对另两个色彩分量的压缩编码就转变成对相关系数的编码。 - The dissertation combine the theory , with using integers dct transform to realize grey image lossless compress with the method of reversible color space integers transform and reversible integers dpcm prediction to realize lossless compress from grey image to color image with huffman coding method via visual c + + program
本文借鉴整数dct变换实现灰度图像无损压缩的理论研究成果,将其与可逆的颜色空间整数变换和可逆的整数dpcm预测相结合,采用哈夫曼编码方法,用vc编程实现了从灰度图像到彩色图像的无损压缩。 - On the basis of describing the situation of current logging technology and considering the atrocious environment and the superiority of video imaging well - logging , the logging system consists of hardware and software sub - system in this paper . according to the objective condition of logging , the design of hardware has taken special treatments : high - temperature - proof protection with particular equipment for the whole circuit , video collection with ccd , temperature signal gathering by pt resistance and v / f transform , depth measurement through photoelectric encoder and jitter elimination circuit
