Landmark Motion History Image (LMHI)

LMHI represents the motion of a given a sequence of 2D facial landmarks in a single image

Given a sequence of 2D landmarks, in X and Y matrices, the LMHI function represents the motion of the facial landmarks in a single image; registration of the facial landmarks is also provided. Further explanation, along with specific examples, can be found in the LMHI.m as comments. X and Y matrices for running the example are included in the XY.mat, and the expected output is also included both as MATLAB figure and a jpeg image, for verification purposes.
