Kanade-Lucas-Tomasi (KLT) Feature Tracker

Problem Statement
• I, J : 1 st and 2 nd grayscaled images
• I(x,y) : gray value of I at [x y] T
• Let u=[u x u y ] T be a point on the 1 st image I
• The goal is to find v on J, where I(u) and J(v) are
similar. (v= u+d = [u x +d x u y +d y ] T )
• d=[d x d y ] T is the image velocity at u
or the optical flow at u.
