ORB feature based matching of two-dimensional electrophoresis gel images

Abstract

An alternative approach was applied for matching two - dimensional Protein gel Electrophores is images for real - time applications use. For the feature extraction of protein spot the ORB feature descriptor was used. The matching of extracted ORB features was achieved using the Brute Force matcher. Lastly, the planar homography transformation matrix is found and perspective transform applied gaining the warped two - dimensional electrophoresis image. The matching performed in 2.1 second of selected gel region having 2855x1176 initial resolution gel image with ~9 1 % accuracy using standard desktop computing.
