DecimateMatr(matr,pitch,size=None,center=(0,0)) - returns the decimated matrix

Parameters:

• matr - arr matrix, typically retrieved by GetImageMatr function

• pitch - a scalar or tuple (px,py) for either aniso decimation or not. Using integers as pitch increases decimation speed (0..n)

• size - tuple (dx,dy) - ROI in matr to decimate, if omitted or None decimates whole matr

• center - tuple (x,y) - center offset if size<matr.dim(), defaults to matr center if omitted or None

Note: ROI is clipped if outside image, causing smaller output size

Example 1: Decimate image

# used to provide access to image from python
img=GetImageMatr('Image') #get the image
dec=DecimateMatr(img,2)
SetImageMatr('Decimated',dec)
