Tiivistelmä
More images are produced than ever before. Images are used for many different purposes and most often it is preferred to have an image that is as high-quality as possible. In addition to the fact that a high-quality image might be more pleasant to look at, it also helps in analyzing the image. One challenge in imaging is images being out of focus. One solution for this problem is to take many images of the same scene with different parts in focus and to combine these images into one sharp image with the help of multi-focus image fusion. In an ideal case this leads into one image that is completely in focus, removing the need for inspecting different parts from multiple images. Image fusion is a common operation in optical microscopy but less common with images that are produced with an electron microscope.
In this bachelor’s thesis a graphical user interface was created using the MATLAB App Designer for an algorithm that performs multi-focus image fusion and depth estimation for 3D-ren dering for electron microscope images. While developing the app, user-friendliness was considered so that the use of the application would be possible even without instructions.
In the theory part of the thesis, we first go through the fundamentals of how electron microscopes work with the focus on scanning electron microscope, since it was used for producing the test data for this thesis. Next the image fusion, depth estimation for 3D-rendering and image segmentation that are used in the thesis are examined. After the theory part, the application’s software development and design choices are discussed. Lastly in the results part of the thesis the final state of the application and how to use it is shown and image fusion and 3D-point cloud examples that were made using the application are shown.
The application’s development project reached its goal, and the developed application works as a base for possible further development. These further developments could be towards adding new features and improvements to the user-friendliness.
