public class HVQMatcher

extends java.lang.Object

Constructor Summary

HVQMatcher(int[][][] et, float[][][] dt)
First parameter is a hierarchy of vector quantization tables Second parameter a pair of tables encoding the x and y discrepancies appropriate for any pair of codebook entries

HVQMatcher(java.lang.String dbname, java.lang.String encodename, java.lang.String dispname)
Initialises a matcher from a named database

Method Summary

Jimage

match(Jimage leftorig, Jimage rightorig) Takes two images and returns x,y disparity images disparities in fractions of source image dimensions needed to move the left image points onto corresponding points on the right image.

Method Detail

match

public Jimage match(Jimage leftorig,
                    Jimage rightorig)

Takes two images and returns x,y disparity images disparities in fractions of source image dimensions needed to move the left image points onto corresponding points on the right image. The left image is quantized on a uniform grid of 4x4 squares, the right image is quantized on 4 overlapping patterns of 8x8 squares, identified by the red-purple, blue-purple, red-green and blue-green grids. Thus each square in the left image is at the center of one larger square on the right image under one of the 4 quantizations of that image
