2. Description of the Related Art
When a robot recognizes an object or a person in an indoor or outdoor environment, a technique for separating an input image into a front view and a background is important. In a recognition technique, an object may be erroneously recognized due to a feature point extracted from a place other than an object. Even when using a boundary-based recognition algorithm, a recognition rate is lowered due to misjudgment of an object boundary. Accordingly, accurate separation of an image into a front view and a background is important in a robot recognition technique.
There are various methods of separating a front view and a background of an image. A method of expressing an image using a Markov Random Field (MRF) model and minimizing energy using graph cut or Belief Propagation (BP) is generally used. To accurately separate a front view and a background, a predefined front view region and a predefined background region are necessary.
Algorithmic results for separating a front view and a background of the related art is not completely automated. A front view region and a background region are set by a user and the front view and the background of the image are separated based on the set regions.
In addition, in the algorithm for separating the front view and the background in the related art, recognition rate may be lowered due to background noise, edges, or patterns within the image.

It also is desirable that the die and components thereof be formed of inflexible fabric to enable the extrusion apparatus to have a relatively retentive functional life eliminating constant haunt and refilling of parts due to them being subject to the high internal atmospheric pressure and friction of the moving elastomeric stream. 
 Certain of the anterior art patent discourse above disclose an extrusion head which admit means of varying the stream of material through an bulge orifice to regulate the visibility of the extrusion material. However, none of these patents disclose the specific shape and use of a rigid metal die element having two opposed tapered surfaces, one of which regulates the size of the outer extrusion orifice and the other automatically compensates for pressure changes in the stream of elastomeric material adjacent the bulge orifice to supply a smooth, master varying out profile of a tubular extrudate as in applicants' apparatus and method acting steps jell forth below. 1. airfield
