dc.description.abstract | In the aspect of biomedical diagnose, it still have to check the biomedical image one by one of the capsule endoscope. The reason is the typical capsule endoscope can just take the front images, all of the images have rarely relation between each other during the image taking. So the research purpose a new idea of capsule endoscope to get the ring field image, it is called ring field capsule endoscope. The capsule use a cone mirror to get the capsule side images, it not only can solve the problem that the typical capsule endoscope is difficult to get the dead spaces images in the intestines, but also can get the side images which have relation between each other, so we can use the images to recognize it, after connect all of the images we can project it to the cylindrical mode, restore three dimension ring field image.
This research use MATLAB software to process the images. First, we use the ring field capsule endoscope to do experiment and get ring field image, then process the images by two algorithm, they are Pearson correlation coefficient and mean absolute error respectively. We can find the two methods can find the same optimum location after computing, but the compute time is very difference. It can decrease the time to 4 second by using mean absolute error, but it can just decrease the time to 12 second by Pearson correlation coefficient. After connect all of the images we can project it to the cylindrical mode, and design the cylindrical radius decrease linearly to construct a three dimension view, and restore the real ring field image.
