Title: Innovations of Andrew Docherty

Introduction

Andrew Docherty is a notable inventor based in St. Leonards, Australia. He has made significant contributions to the field of imaging technology, holding a total of five patents. His work primarily focuses on methods that enhance image registration and segmentation in medical imaging.

Latest Patents

One of Docherty's latest patents is an image registration method that adjusts a displacement field relating positions of pixels between at least two images. This method involves associating each pixel of the first and second images with a label and mapping a first pixel in the first image to a second pixel in the second image based on a vector of the initial displacement field. The process includes determining a covariance score for a set of third pixels, which helps in refining the adjustment shift vector based on statistical dependencies.

Another significant patent is related to robust segmentation of the retinal pigment epithelium layer. This method identifies multiple regions using captured image data of the eye and fits a curve into these regions. A curve score is determined based on the distance between the fitted curve and the regions, allowing for the classification of some regions as part of the retinal pigment epithelium.
