Analysis and Detection of Cholesterol by Wavelets based and ANN Classification

Now a day's according to the fact that excess Cholesterol is one of the most prevalent diseases of human body system. Further determination of the exact location of Cholesterol in the body is a big challenge. As of now, there seems to be no scientific tool which precisely determines the presence of cholesterol. However, Mammography has drawbacks which yields 34% false negative rate which is too high. This has been overcome by digital mammography but has limitations regarding the x-ray exposure. Moreover, Image cannot be altered and film processing is slow. CAD based techniques provides increase in Cholesterol detection rate by 7.62%. Nevertheless, image segmentation in CAD based technique has advantage over spatial intensity but estimating the proper prior distribution remains a challenge. There are many Methods of medical imaging viz., magnetic resonance imaging (MRI), x-ray computed tomography (CT), ultrasound imaging (US) etc that can examine different parameters of human body. The detection of cholesterol is crucial for the doctor to determine the status of the Cholesterols and also to visualize any abnormalities present in the Cholesterol. The detection of abnormalities of Cholesterol inside the body is a main field of study in medical research using bio-medical image processing. Due to some abnormalities (speckle noise) in ultrasound or MRI images or US or CT and artefacts, wrong diagnosis may happen by analysing the scanned image. Therefore in this proposed work the main focus is to design the algorithm based on level set segmentation, wavelets filters and artificial neural network (ANN) architecture for detection of Cholesterol in real time using biomedical images with the help of MATLAB with maximum accuracy of 98.8%.
