Choose a web site to get translated content where available and see local events and offers. This matlab function each mesh line segment and face has a constant color determined by the color value at the endpoint of the segment or the corner of the. The lighting command sets the facelighting and edgelighting properties of surfaces and patches appropriately for the graphics object. The surf, mesh, pcolor, fill, fill3, surface, and patch functions create graphics objects that are affected by light sources. It started out as a matrix programming language where linear algebra programming was simple. Lighting is an effective means to enhance the visibility of surface shape and to provide a threedimensional perspective to your visualization. Face detection is the process of identifying one or more human faces in images or videos. We support both hardware and software based applications on face recognition for students from various disciplines. This face detection using matlab program can be used to detect a face, eyes and upper body on pressing the corresponding buttons.
Ok so matlab has its own lighting model that you can use to add ambientdirectional light sources within a 3d space e. A matlab based face recognition system using image processing and neural networks. Project presentation on face detection using matlab 7. Matlab provides several commands that enable you to position light sources and adjust the characteristics of lit objects. This tutorial gives you aggressively a gentle introduction of matlab programming language. In order for the lighting command to have any effects, however, you must create a lighting object by using the light function.
