本课题考虑利用主成分分析（PCA）对多层面的源图像序列进行分解，建立各源图像的主成分序列，进而对源图像的主成分序列进行融合处理，最终得到完整的融合图像。
本课题中的算法利用主成分分解可以保留原数据中的主要信息这一特点, 由源图像获取数据的协方差矩阵, 协方差矩阵的特征值和特征向量, 据此确定图像融合算法中的加权系数和最终融合图像。并且本课题对基于主成分分析的特征融合算法的运算进行了一定的深入研究。最终试验表明, 应用该算法融合后的图像取得了满意的效果.

Title Based on principal component analysis (PCA) algorithm microscopic image
Abstract As an important field in image fusion, microscopic image fusion has been applied widely in the field of biomedicine, microelectronic product visual inspection and material inspection and so on. How to get the information and use efficient ways for fusion is an important topic in pattern recognition because there is a lot of information in images. The feature fusion of image has more and more important applications, such as in target recognition, medical treatment and biology feature recognition.
This topic considered the principal component analysis (PCA) of the multi-level decomposition of the source image sequences, to establish a main component of the sequence of source images, and thus the main component of the source image fusion sequence, the full integration of the final image obtained.
The subject of the principal component decomposition algorithm can preserve the original data in the main message of this feature, access to data from the source image covariance matrix, covariance matrix eigenvalues and eigenvectors, which determine the weighted image fusion algorithm coefficients and final fused image. And this topic based on principal component analysis feature fusion algorithm works for a certain amount of in-depth study. Final tests showed that the application of the algorithm fused image with satisfactory results.
