The Importance Of Quantitative Method In Research

It is very important to find the appropriate literature related to the research before starting it. It will be useful to know the previous articles related to research and their results. This will help us in understanding existing techniques and their drawbacks in a better way, so that we can improvise those techniques or overcome the drawbacks with new techniques in our research.

There are two types of research 1) Qualitative Method and 2) Quantitative Method

In our research, we are implementing the quantitative method.

Quantitative Method:

Quantitative method is a method where data can be reduced to numbers or numerical values which is known as numerical analysis. The researcher needs to have a proper plan and data should be collected according to it. The main goal of this method is to develop and employ mathematical models, hypothesis related to our research. %the concerned phenomena%\cite{ashley}. Quantitative method has the following steps:

\begin{enumerate}

\item Develop theories and hypothesis for the expected results.

\item Develop methods for measuring the data.

\item Data collection

\item Data analysis and extraction of results

\item Application of results.

\end{enumerate}

Data collection:

In order to separate the finger vein sample from background, we have to trace each column of finger vein sample to find the outer bound of the finger using the method presented in [10] [<-v1]. This method will detect both upper and lower bounds of the finger vein. Next, we determine the center of finger vein by calculating the midpoint with upper and lower bounds. We then find the rotation and translation parameters based on the attained finger vein sample by matching it to the original image reference axis [3]
