computation

When the computed transformation is applied to the model vertices and the transformed Lacoste POLO Shirts are backprojected onto the image plane, a remaining error between image features and their corresponding imagemodel features can be noted, this is due to the computation Lacoste Polo Shirts introduced by the data processingalgorithms used in the several modules of the recovery system which are generally cumulative.So in order to refine the computed transformation, an optimization procedure based on Levenberg-Marquardt method is used to minimize the mean 2D square distance between accurate nodes extractedfrom scene image and their Ralph Lauren Polo shirts. Let D be the criterion to minimize,
