WEEK 10: OVERVIEW CHAPTER 3 (METHODOLOGY)

Tuesday, 03 May 2022 

The most proposed previous methodology has been changed for better performance in this project analysis. Also, to define whether the brain of the MRI images has a tumor or not have to use the MATLAB app, not GUI, as previously method proposed. Below are the previous and new approaches to achieving the objectives of this project. 

Figure 1: Show the previous methods proposed. 

In previous methods, it comprises three stages: pre-processing, Image enhancement, and Image segmentation. For final results will display by the GUI app in MATLAB. This process will take time in Pre-processing by converting the image into greyscale by help with image enhancement. For GUI, MATLAB has advanced its features in using app designer than GUI for better analysis and results. 

Figure 2: Show the new approach in this project. 

New methods also include three stages: Anisotropic filtering, Image segmentation, and morphological operation. Anisotropic filtering is an alternate process to pre-processing and image enhancement by reducing noise in MRI images. While the morphological operation has been used to detect and specify the location of the presence of the tumor by that to achieve the objectives as stated. The results display using app designer in MATLAB to give a better perspective of the operations performance.
