This paper describes the shadow puppet play which is a modelling technique using OpenGL in order to produce realtime shadow image. Besides, the novelty of this paper is to improve the interaction of shadow puppet play by applying both the texture mapping and the blending technique. The integration of these methods gives the special lighting effects that are vital for the quality improvement of ...

Accurate, textured, 3D computer models of objects are of increasing interest in many disciplines, e.g. archeology. Laser scanners provide a very precise way of gathering data for such models; however, a number of steps are necessary before this new laser data can be imported into a computer model that is ready for rendering. This work discusses the processes undertaken to develop a simple to us...

In this paper, an extension to the traditional method for creating video textures is presented. By exploiting the symmetric properties of the frames in a given video sequence, a new endless video stream or video loop is generated by reversing video playback when appropriate. We aim at a larger set of possible input video’s for video texture creation, including captured motions containing no smo...

Surface Detail: We have discussed the use of lighting as a method of producing more realistic images. This is fine for smooth surfaces of uniform color (plaster walls, plastic cups, metallic objects), but many of the objects that we want to render have some complex surface finish that we would like to model. In theory, it is possible to try to model objects with complex surface finishes through...

We propose a new method for background modeling. Our method is based on the two complementary approaches. One uses the probability density function (PDF) to approximate background model. The PDF is estimated non-parametrically by using Parzen density estimation. Then, foreground object is detected based on the estimated PDF. The method is based on the evaluation of the local texture at pixel-le...

The 3D Morphable Face Model (3DMM)[1] has been used for over a decade for creating 3D models from single images of faces. This model is based on a PCA model of the 3D shape and texture generated from a limited number of 3D scans. The goal of fitting a 3DMM to an image is to find the model coefficients, the lighting and other imaging variables from which we can remodel that image as accurately a...

Creating realistic images has been a major focus in the study of computer graphics for much of its history. This eeort has led to mathematical models and algorithms that can compute predictive, or physically realistic, images from known camera positions and scene descriptions that include the geometry of objects, the reeectance of surfaces, and the lighting used to illuminate the scene. These i...
