Non rigid motion estimation is one of the main issues in computer vision. Its applications range from civil engineering or traffic systems to medical image analysis. The challenge consists in processing a sequence of images from of a physical body subjected to deformation processes and extracting its displacement field. In this paper, an iterative Block-Matching technique is proposed to mearsure displacements in deformable surfaces. This technique is based on succesive interpolation and smoothing phases to calculate the dense displacement field of a body. The proposed technique was experimentally validated by studing the Yosemite sequence and it was tested in the analysis of stregth test and biomedical images.
