This system includes ? (1) the diameter of each spots and the distance between each spots on the die surface had to be known before the detection process, (2) a sort of template matching was repeated to Site URL List 1|]# classify dice and all spots associated to each die. In addition, an electromechanical dice gambling machine [3] was established to detect dice location based on contactless electronic ID keys and a scanner. As machine vision was not provided during the recognition process, the suspicion of cheating cannot be eliminated.Because of the above-mentioned issues, a novel auto-recognition system is proposed to estimate the location of each die and the score of dice accurately and effectively in the games Inhibitors,Modulators,Libraries using machine vision techniques.
In this paper, the modified unsupervised Inhibitors,Modulators,Libraries grey clustering algorithm is proposed to establish an auto-recognition system for several dice in the games. The grey clustering algorithm was primarily based on the grey theory Inhibitors,Modulators,Libraries [5-10]. The aims of grey theory are to provide relational analysis, predication, decision, control, and clustering data for the grey system. The grey theory Inhibitors,Modulators,Libraries has been applied to research in industry, social system, ecological system, environmental system, education, business management, and traffic control. The grey clustering algorithm is an essential topic in grey system theory. Hsu et al. [11] proposed a system to predict variations of stock market using the grey clustering method. Yang et al.
[12] applied a grey prediction model Inhibitors,Modulators,Libraries to predict the recovery rate of vegetation Inhibitors,Modulators,Libraries according to the satellite images of landslide caused by an earthquake.
The object of the present study is to automatically recognize the score of dice. Brefeldin_A This study develops an iterative calculation that is suitable for dice identification, and is organized as follows: an image acquisition system, an image processing method, the proposed modified unsupervised grey clustering algorithm, and an auto-recognition system for dice are Inhibitors,Modulators,Libraries presented in Section 2. Experimental results are summarized in Section 3. Section 4 contains conclusions about the proposed system.2.?Materials and Methods2.1. Image acquisitionIn order to obtain online images for auto-recognition, a machine vision system was being developed.
This system kinase inhibitor Axitinib includes a CCD (coupled-charge device) monochrome camera (WAT-902B, Watec Inc) with a zoom lens, a frame Inhibitors,Modulators,Libraries grabber (Meteor, Matrox Inc), and a personal computer (Intel Pentium 4 processor 2.
4 GHz). Visual Basic 6.0 programming is linked to grab the monochrome images of 640��480 pixels and perform Dacomitinib the image processing. The CCD camera was employed for image acquisition with a light intensity of 4150 lx and F4.0 opening selleck Belinostat (iris diaphragm). The images are stored in the hard drive as tagged image file format (TIF).2.2. Image processing and modified grey clustering algorithmSegmenting the spot images of dice is an important procedure in the classification process.
