Joint Estimation of Object Motion and Point Light Illumination for 3D–Object–Based Analysis–Synthesis Coding
In video telephone scenes to be transmitted at low data rates non–diffuse scene illumination has to be expected. In this contribution, non–diffuse scene illumination and 3D object motion is estimated concurrently from a monocular image sequence. Image analysis uses the source model ”3D rigid moving objects with non–diffuse illumination”. The illumination is modeled by a distant point light sour...

متن کامل3D Motion Estimation of Articulated Objects for Object–Based Analysis–Synthesis Coding (OBASC)
An algorithm for motion estimation of articulated 3D objects for object–based analysis–synthesis coding (OBASC) is presented. For motion estimation an articulated object is first decomposed automatically into flexibly connected object– components. Each rigid 3D object–component is assumed to be connected to the object by spherical joints. Then, the 3D motion of the largest object–component is e...
متن کاملJoint position estimation for object-based analysis-synthesis coding
An object–based analysis–synthesis coder for coding moving images at low data rates is investigated. The coder is based on the source model of articulated three–dimensional objects. This model describes the real objects by means of model objects defined by shape, motion and color parameters. The model objects may be articulated, i.e. they consist of several rigid object components linked to eac...
متن کاملIllumination Compensated Motion Estimation for Analysis Synthesis Coding
3D Image Analysis and Synthesis, pp. 61–66,Erlangen, November 1996. In this paper we present two methods to improve the accuracy of three-dimensional motion estimation in analysis synthesis coding by using illumination models. A Lambertian and a reflectance map approach are given which are both computationally efficient. Experiments on real images show that the mean squared error between synthe...
