positive

public boolean positive

Is this patch positive, i.e. representative of the object

source

public FImage source

The image to extract this patch from

window

public Rectangle window

The window to extract form the source

normalisedPatch

public FImage normalisedPatch

The extracted patch, might be null, might be the SLUT_WORKSPACE.

Method Detail

zoomAndNormaliseTo

protected FImage zoomAndNormaliseTo(FImage holder)

A function which uses ResizeProcessor.zoom(FImage, Rectangle, FImage, Rectangle, ResizeFilterFunction) on a to put window form source into normalisedPatch. This is not a convenient function but it allows for very efficient resize/normalisation process (with minimal new stuff constructed)

Parameters:

holder -

Returns:

the holder as a convenience

calculateVariance

public float calculateVariance()

calculate the variance, sets the valueImg if it is null

Returns:

an inefficient way to calculate variance of this window, a new image is constructed!

prepareNormalisedPatch

public void prepareNormalisedPatch()

for construction of a new normalised patch
