## Word meaning ambiguity :Dataset, time series, observation

Hi everyone, I want to feed PCA(principal component analysis) with a matrix(data points) but I?m kind of confused how these points are defined. Below I have a random process Vi(t) and I want to check my definitions of Dataset, time series and observations with you. Vi(t); Observation: for m

## Principal Component Analysis A newbie question -originally posted in un related forum

Hi guys, I'm trying to learn PCA. as an example I have just 2 points in my 3-D space. using PCA(eigen vectors) the outcomes are the principal component: line connecting these 2 points the 2 other orthogonal axes in my opinion could be anywhere in the plane perpendicular to this connecting i wonder what is the PCA criteria to give me t

## Principal Component analysis in VHDL Pls help??

Hi I am doing a project on FPGA based image processing. I want to implement "principal component analysis"(PCA) in VHDL.please tell me how to do....if any one has ready made code please mail me at harivadakara@gmail.com. Thanks&Regards Hari

## Principal component analysis

hi.. Can i get help with the differences between 1D, 2D and 3D principal component analysis in face recognition.. Also how 2D pca logically works. It will be helpful to fine some 2D pca related links. thank you.

## blind source separation

i need code to separate speech signals using independent component analysis and principal component analysis..

## Is there any one working or video watermarking

You may try this Digital video watermarking using singular value decomposition and two-dimensional principal component analysis and refer page no 50 for matlab implementation regards bassa

## PCA on complex valued data

hi everyone i have a set of complex valued vectors which i want to perform principal component analysis on. so my data matrix will be all the vectors putten as columns of the matrix beside each other where the number of components of each vector is 10 and the total number of vectos is 1000, so that my data matrix's size (...)

## Help me starting a research project on face detection

First choose the method by which you would like to detect the face in an image there are various IEEE papers available on Face Detection Some are principal component analysis Template Matching Eigen Based Choose the appropriate method that you want to learn from the above and search IEEE/Springer papers accordingly

## KL transform implementation

KL transform is also known as PCA(principal component analysis) and SSA(singular spectrum analysis) See this or attached file (one of my colleagues found it somewhere in internet long time ago) This is example for 1D signal, but I think you can
