Field Detail

sigma0

public float sigma0

Amount of blur at the first level in the image pyramid. Recommend 1.6

numScales

public int numScales

Number of scales in each octave. The amount of Gaussian blur will double this number of images in the octave. However, the number of actual images computed will be numScales + 3 and the number of difference of Guassian images will be numScales + 2.

firstOctave

public int firstOctave

Specified the first and last octaves. Each octave is a factor of 2 smaller or larger than the input image. The overall size of an octave relative to the input image is pow(2,-octave)

lastOctave

public int lastOctave

Specified the first and last octaves. Each octave is a factor of 2 smaller or larger than the input image. The overall size of an octave relative to the input image is pow(2,-octave)
