In blind source separation (BSS) applications, the number of the signal sources is not known. When the number of the sensors is less than that of the signal sources, this problem is called over complete BSS' (OC-BSS), which is a difficult problem due to lack of information in observations. In this paper, a feedback approach and its learning algorithm are proposed for the OC-BSS. The number of the...
We have shown that the coding scheme can be applied to codes with a sum-product(SP) decoding algorithm \cite{kamabekatouMag}. We suppose that we use two different codes, and SC_{2}$, with different error correcting capabilities as constituent codes. Without loss of generality, we can assume that is stronger than and the rate of SC_{2}$, therefore, less than that of $C_{ 1 }$. From...
This paper describes a new method for object recognition from a stereo image. Namely, a combinatorial optimization method and a pattern recognition algorithm based on synergetics are applied to the identification of planes in a 3-D object and of plane figures, respectively. A plane is constructed by the combination of edges and the plane shape is recognized using synergetics.
