ABSTRACT
The 3D image gives the experience of the invisible dimension of the 2D image. Many researchers work for a display that projects 3D images in a way that makes them visible from all angles and does not require extra accessories. In this paper, we propose an algorithm to construct a 3D image form a 2D image. In which two major techniques are utilized namely segmentation and displacement map. Segmentation technique is used to classify foreground and background objects which plays an important role in 3D imaging. Our focus is only on the foreground of an image because that relates and enhances the overall composition of an image. Displacement map technique is used for constructing the 3D perception of foreground object that will mimic the quality predictions of 3D perception.
Keywords: 2D image, 3D image, segmentation, displacement map
In an image, objects low or directly in front of us are perceived as closest to us and are in the foreground. They are larger, clearer, and brighter than those "behind" them. Objects at a medium distance are perceived as mid-ground; they are in the middle of the frame. Objects farthest from us, in the background, are usually higher in the picture; they seem less clear, and their colors are less intense than those in both the foreground and middle ground.
To understand an image, the first step is to identify foreground and background so that we can focus on an interested object. In computer vision application, object detection is fundamental and most important steps for video analysis[9]. Therefore, in 3D modeling, foreground and background have its own importance. 3D modeling is a technology through which three-dimensional models of any given object can be created. The product design process has become easy with 3D modeling as we can create three-dimensional models virtually for any object no matter how gigantic or micro it is. This very fact helps to create an exquisite design for any product (e.g. orthodontic diagnosis)[4].
3D means three-dimensional, that is, something that has a width, height, and depth (length). Our physical environment is three-dimensional and we move around in 3D every day[7]. Humans are able to perceive the spatial relationship between objects just by looking at them because we have 3D perception, also...
