4.1 Design Patterns This chapter will outline the design patterns used in the proposed system. The architect Christopher Alexander argued that design patterns provide common solutions for common problems in programming. In other word, for any problem occurring in our system several times, the core point is to provide an...

3.1 Graphical User Interface Mocks Up Figure 3.1.1 gives an overview of the navigation functionality of the proposed system while Figure 3.1.2 is a screenshot of main graphical user interface. The user can decide to change the background from black to white or from white to black. Figure 3.1.1: Navigation...

2.1 Overview In this chapter, I mainly start with some researches about the potential blob detection techniques and tools, like LoG (Laplacian of Gaussians) for the smoothing and filtering of images, Hough Transform for the parameterized detection, the simplest blob detection technique SimpleBlobDetection and the integrated development library OpenCV. 2.2...
