EMGU Face Recognition
Using EMGU to perform Principle Component Analysis (PCA)
... by Sergio Andrés Gutiérrez Rojas and his original article (codeproject). The reason that face recognition is so popular is not only it’s real world application but also the common use of principle component analysis (PCA). PCA is an ideal method for recognising statistical patterns in data. The popularity of face recognition is the fact a user can apply a method easily and see if it is working without needing to know to much about how the process is working. -

WaveSorter
A powerful, versatile tool for offilne spike analysis and sorting
WaveSorter emphasizes dynamic visualization and versatility. Slider controls let the user select any coefficient or sample from any of several transforms, which can then be plotted to either axis of a 2D histogram (scatterplot). Within the waveform space, cursor-based controls let the user select subregions of the waveform space or individual waveforms to view. The user may cluster waveforms manually or via one of several popular clustering programs. The classification along with waveform... -

NEural SOrter
a tool for offline electrophysiological recording analysis
... recordings - view your recordings as superimposed waveforms or as waveforms in time - use PCA and Height vs Width analysis to extract waveform features - use Vectorial Quantization or K-Means anaysis to sort the waveforms (spikes) classify spikes as diferent units - use templates to sort spikes - save the analysis results as NeuroShare format Developers: Daniel de Santos Sierra Cristina Soto Sanchez -

dPCA
dPCA is a data exploration technique using metadata
Demixed Principal Component Analysis (dPCA) is a new data exploration technique. Just like Principal Component Analysis (PCA), dPCA searches for a subspace that captures a high amount of information about a data set. However, often your data points have labels like time, stimulus presented, reward achieved, etc. In contrast to PCA, that completely ignores these labels, dPCA benefits from the labels and tries to find components that capture variance due to only a small subsets of the labels... -
