ABSTRAK

Pada citra medis identifikasi dari tepi objek atau daerah yang diinginkan dapat menyediakan informasi yang berguna untuk diagnosis dan perawatan penyakit. Proses segmentasi yang terlibat dapat dilakukan secara manual tetapi sangat bergantung pada keahlian pengguna. Tingkat akurasi segmentasi yang dihasilkan metode manual juga rendah karena pengaruh intra- dan inter-observer. Oleh karena itu dibutuhkan metode segmentasi secara otomatis. Dalam tugas akhir ini diimplementasikan sebuah metode segmentasi citra medis dengan deteksi tepi kontur berbasis pelacakan target secara dinamis. Jalur pada tepi objek dihasilkan melalui deteksi tepi dengan menerapkan sembilan operator arah. Selanjutnya target-target di sepanjang jalur tepi objek dalam citra dilacak dengan menggunakan teknik modified edge-following.Dari percobaan yang dilakukan terhadap citra Magnetic Resonance dan Dental Panoramic Radiograph metode ini mampu melakukan segmentasi objek dengan cukup baik. Metode ini juga memiliki keunggulan dimana keseluruhan proses segmentasi dilakukan secara otomatis.


ABSTRACT

In medical images identification of object boundary or region of interest can provide useful information for diagnosis and treatment of disease. The segmentation process involved can be done manually but very dependent on user expertise. The resulting accuracy of manual segmentation method is also low because of the influence of intra-and inter-observer. Therefore automatic segmentation method is needed. In this final project medical image segmentation using edge contour detection algorithm based on dynamic target tracking is implemented. Path on objects edge is generated through edge detection by applying nine directional operators. Subsequently targets along the path on objects edge in the image is tracked using the modified edge-following technique. From experiments performed on Magnetic Resonance and Dental Panoramic Radiograph images this method is able to segment objects properly. This method also has advantage in which the whole segmentation process is performed automatically.
