A warping based approach to correct distortions in endoscopic images

Abstract—This work proposes a technique to correct distor-tions in endoscopic medical images using concepts of morphing and warping. A triangular mesh is used to apply transforma-tions in each region of the image separately. A chess pattern is used to verify the distortion of the endoscopic system. The same pattern is used to generate the mesh and the equations for the transformations of the warping and morphing step. After the computation of each triangle affine transformations the same equations are used to correct the real endoscopic images
