Constructs the Gaussian pyramid for an image

dst = cv.buildPyramid(src)
dst = cv.buildPyramid(src, 'OptionName',optionValue, ...)

Input

• src Source image. Check cv.pyrDown for the list of supported types.

Output

• dst Destination vector of Maxlevel+1 images of the same type as src. A cell array of images. dst{1} will be the same as src. dst{2} is the next pyramid layer, a smoothed and down-sized src, and so on.

Options

• MaxLevel 0-based index of the last (the smallest) pyramid layer. It must be non-negative. default 5
• BorderType Pixel extrapolation method, ('Constant' isn't supported). See cv.copyMakeBorder for details. Default 'Default'

The function constructs a vector of images and builds the Gaussian pyramid by recursively applying cv.pyrDown to the previously built pyramid layers, starting from dst{1}==src.
