Query: Improving the Otsu Thresholding Method of Global Binarization Using Ring
  Theory for Ultrasonographies of Congestive Heart Failure   Ring Theory states that a ring is an algebraic structure where two binary
operations can be performed among the elements addition and multiplication.
Binarization is a method of image processing where values within pixels are
reduced to a scale from zero to one, with zero representing the most absence of
light and one representing the most presence of light. Currently, sonograms are
implemented in scanning for congestive heart failure. However, the renowned
Playboy Bunny symbol representing the ailment becomes increasingly difficult to
isolate due to surrounding organs and lower quality image productions. This
paper examines the Otsu thresholding method and incorporates new elements to
account for different image features meant to better isolate congestive heart
failure indicators in ultrasound images.
