Compression of Breast Cancer Images By Principal Component Analysis
The principle of dimensionality reduction with PCA is the representation of the dataset ‘X’in terms of eigenvectors ei ∈ RN of its covariance matrix. The eigenvectors oriented in the direction with the maximum variance of X in RN carry the most relevant information of X. These eigenvectors are called principal components [8]. Ass...

متن کاملMotion Estimation by Means of Principal Regression
This paper presents an approach where the optical flow between frames of video sequences is estimated according to a pel-recursive strategy through the use of a principal component regression (PCR). This is a simple choice when it comes to treat mixtures of motion vectors due to the fact that it is not essential to have too much knowledge on their statistical properties (although they are suppo...
متن کاملPrincipal Component Analysis of Fractional Brownian Motion
This paper gives an analytical proof of the conjecture [1]: when the dimension M of the auto-covariance matrix is large, the eigenvalue spectrum from Principal Component Analysis (PCA) of a fractal Brownian motion (fBm) process with Hurst parameter H decays as a power-law: λm ∼ m −(2H+1), m = 1,..., M . This resolves the interesting puzzle why PCA based H estimator can yield right results for f...
متن کاملDynamics of βB2-Crystallin Motion Based on Principal Component Analysis and Normal Mode Analysis
The primary function of lens is to focus images perfectly on the retina. Lens crystallins however are flexible nanomachines that frequently accomplish their biological function by collective atomic motions in and/or out the lens. Although genetic and biochemical data on the βB2-crystallin protein are available from several sources, the correlation between conformational changes and dynamic beha...
