Firstly, chromatism analysis and wavelet transform are used for color image compression coding. in this method, one of the three color components of a color image ( for example the g component of a rgb color image ) is coded using wavelet transform, and the chromatism between g and other two color components rg = r - g, bg = b - g is coded respectively using chromatism analysis. during decoding, g ~ is first reconstructed using wavelet inverse transform and inverse quantisation, and rg, bg are reconstructed using chromatism analysis inverse transform ; then r, b are calculated by r = g + rg and b = g + bg respectively
其一是應用色差分析和小波變換對彩色圖象進行壓縮編碼,該方法是對彩色圖象的三個色彩分量之一,如rgb圖象的g進行小波變換編碼,而對g與另兩個色彩分量的差值(即rg = r - g和bg = b - g )進行色差分析編碼,解碼則是通過反量化和小波逆變換得到g ^ ,通過色差分析的逆變換得到兩個重構的色差rg ^和bg ^ ,再算出r ^ = g ^ + rg ^ 、 b ^ = g ^ + bg ^ ,最後由r ^ 、 g ^ 、 b ^重構圖象。Finally, this paper also presents a new method specially for color head image compression coding
最後本文還提出了專門針對彩色人頭圖象壓縮編碼的新方法。This method establishes the correlation template between one color component and the other two color components by using color correlation between three color components in each feature regions of a color head image. and it " s only necessary to quantize and code the first color component. during decoding, this color component is reconstructed
該方法利用彩色人頭圖象在各個特徵區域三個色彩分量之間的色彩相關性,建立其中一個色彩分量與另兩個色彩分量之間的相關模板,並只需對第一個色彩分量進行量化編碼,解碼時重構這個色彩分量后,加上極少量的相關模板系數就可解出另兩個色彩分量,從而恢復圖象。Thus the coding of a color head image actually become the coding of a color component. the experimental results show this method not only improve the coding efficient and compression ratio but also obtain satisfactory effect of the reconstructed image. at the same time, this method also enables gray head images to be converted into color head images
這樣對彩色人頭圖象的編碼實質上就變成了對其中的一個色彩分量的編碼,實驗結果表明該方法不僅提高了編碼效率和壓縮比,也能獲得較滿意的重構圖象效果,同時還使得將灰度人頭圖象轉換成彩色人頭圖象成為可能。Coding colour image
編碼彩色圖象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
其二在上面這種方法的基礎上,又提出了利用色彩分量相關性結合小波變換實現對彩色圖象的壓縮編碼,該方法同樣是對彩色圖象三個色彩分量之一進行小波變換零樹編碼,將該色彩分量分割成若干個大小相等不重疊的子塊,計算出該色彩分量在每個子塊中與另兩個色彩分量在同一子塊的相關系數,由此對另兩個色彩分量的壓縮編碼就轉變成對相關系數的編碼。By thoroughly exploring the correlation among the three color components of a color image, this paper presents a new method for color image compression coding from three aspects
本文則著重於對彩色圖象色彩空間相關性的研究,通過充分挖掘rgb三個色彩分量之間的相關性,從三方面提出對彩色圖象進行壓縮編碼的新方法。分享友人
