An approach has been proposed for automatic adaptive subtitle coloring using fuzzy logic-based algorithm. This system changes\r\nthe color of the video subtitle/caption to ââ?¬Å?pleasantââ?¬Â color according to color harmony and the visual perception of the image\r\nbackground colors. In the fuzzy analyzer unit, using RGB histograms of background image, the R, G, and B values for the color\r\nof the subtitle/caption are computed using fixed fuzzy IF-THEN rules fully driven from the color harmony theories to satisfy\r\ncomplementary color and subtitle-background color harmony conditions. A real-time hardware structure has been proposed for\r\nimplementation of the front-end processing unit as well as the fuzzy analyzer unit....
We explore how judgment aggregation and belief merging in the framework of fuzzy logic can help resolve the ââ?¬Å?Doctrinal Paradox.ââ?¬Â\r\nWe also illustrate the use of fuzzy aggregation functions in social choice theory....
This paper presents a methodology to integrate a fuzzy coprocessor described in VHDL (VHSIC Hardware Description Language)\r\nto a soft processor embedded into an FPGA, which increases the throughput of the whole system, since the controller uses\r\nparallelism at the circuitry level for high-speed-demanding applications, the rest of the application can be written in C/C++.\r\nWe used the ARM 32-bit soft processor, which allows sequential and parallel programming. The FLC coprocessor incorporates a\r\ntuning method that allows to manipulate the system response. We show experimental results using a fuzzy PD+I controller as the\r\nembedded coprocessor....
The purpose of this paper is to study theory of two different kinds of a-layer order-preserving operator space, namely, ?a-opos and\r\n?*\r\na ()-opos. The former kind of space is formed by a-layer function in L-fuzzy order-preserving operator space. The later kind\r\nof space is derived by local a-remote neighborhood function, which is related with ?a-opos and a-ideal. We study characteristic\r\nproperties of the two kinds of spaces, respectively, and give some applications to show the intimate relations under two different\r\n?*\r\na ()-oposs....
The relations between rough sets and algebraic systems have been already considered by many mathematicians, and rough sets\r\nhave been studied in various kinds of algebraic systems. This paper concerns a relationship between rough sets and ternary\r\nsemihypergroups. We introduce the notion of rough hyperideals and rough bi-hyperideals in ternary semihypergroups. We\r\nalso study fuzzy, rough, and rough fuzzy ternary subsemihypergroups (left hyperideals, right hyperideals, lateral hyperideals,\r\nhyperideals, and bi-hyperideals) of ternary semihypergroups...
