Goal: Use line detection to find the line from the fingers

We perform data analysis on the finger recognition using Matlab Hough Peak function. It is the function that we use to detect lines in the picture data set. Our sample photo is the picture of finger showing number two with a yellow background. First, I choose the third matrix of the picture representing B color tone from RGB and eliminated background using Gaussian Method. The picture shown below is the result.

We then used the Hough Peak function to extract lines from the data set. The plot shown below is showing the most detected angle in the picture. We selected the ten peaks from the bin and chose only the lines that is longer than 100 pixels. Here is the result.
