Abstract

There are numerous governmental, social, business, and educational associations that manage large number of handwritten documents. As time proceeded, the content in the handwritten document gets blurred and that cannot be readable. In order to make that text visible and accessible, Document Image Analysis (DIA) is used.  The previous work deals with the pair wise similarities between word-separators as well as unary properties in the document. But there is a failure case, when both the inter and intra word gap is same. Then structured SVM fails to work. The proposed system uses Independent Component Analysis (ICA) algorithm, which transforms multivariate data so as to make its essential structure more visible or more accessible, thus facilitating the analysis of the data. Here the Tamil handwritten document is taken into consideration since the local language is Tamil.

Abstract

Synchronous circuit designs face many challenges such as clock skew, clock jitter and power consumption. Asynchronous clockless circuit design is a solution to these clock issues. Asynchronous circuits have merits of low power, anti-interference, high robustness, and module reusability due to its clockless nature. NULL Convention Logic (NCL) is one of the promising candidates for asynchronous circuit design paradigms. NCL circuits are said to be correct-by-construction and delay insensitive circuits. In this paper, a new methodology for mapping multi-rail logic expressions to NULL convention logic (NCL) gate library is proposed to reduce area and delay of NCL circuits when compared to the existing algorithm.
