研究了奇异值分解在图像压缩中的应用,把共轭梯度法和截断奇异值分解的正则化方法应用于图像恢复中,实验结果表明,这几种数学方法对图像压缩和恢复效果显著.
Several mathematic methods are discussed in this paper.Singular Value Decomposition(SVD) is applied in compressing image.Conjugate Gradients(CG) method and Truncated Singular Value Decomposition(TSVD) regularization method are used in image restoration.Experience results show that those methods have a great effect in image compression and image restoration.
