TWO-STAGE CORRELATION METHOD FOR CORRESPONDENCE SEARCH
First Claim
1. A computer-implemented method for comparing the similarity between two image patches taken from a stereo camera system, preferably in order to compute a depth estimation value for an object in the input field of a stereo camera, the method comprising the steps of:
- receiving from at least two vision sensors, such as e.g. a stereo camera, at least two image patches, wherein each sensor supplies an image patch, andcomparing the received image patches by;
extracting a number of corresponding subpart pairs from each image patch,calculating a normalized local similarity score between all corresponding subpart pairs,calculating a total matching score by integrating the local similarity scores of all corresponding subpart pairs, andusing the total matching score as an indicator for an image patch similarity,determining corresponding similar image patches based on the total matching score.

Abstract
The invention presents a method for comparing the similarity between image patches comprising the steps of receiving form at least two sources at least two image patches, wherein each source supplies an image patch, comparing the received image patches by extracting a number of corresponding subpart pairs from each image patch, calculating a normalized local similarity score between all corresponding subpart pairs, calculating a total matching score by integrating the local similarity scores of all corresponding subpart pairs, and using the total matching score as an indicator for an image patch similarity, determining corresponding similar image patches based on the total matching score.
