Abstract:
The Ethiopia Orthodox Tewahedo Church (EOTC) has its own icons the people used for
reverence. Currently, the Ethiopian Orthodox Tewahedo Church (EOTC) icons have mixed with
different western country icons due to the advancement of globalization and influences of
western cultures. In the previous several types of research can be done in the area of icon
classification and recognition by using image processing techniques. However, the Ethiopian
Orthodox Tewahedo Church (EOTC) icon detection is still a problem for the people who do not
know about the Ethiopia Orthodox Church dogma and doctrine. Most of the previous work
focuses on humans like face appearance icons based on Byzantine’s icon canon by considering
only texture, shape, and color. They used the handcrafted feature extraction techniques only. In
this thesis, we developed a model using a combination of the Gabor feature, Local feature, and
Conventional Neural Networks (CNN) together to extract the deep feature and the local feature
of the Ethiopian Orthodox Tewahedo Church icon by considering the most relevant feature of
EOTC icon like shape, position, angle of orientation, texture, and direction. To detect whether
the icon is Ethiopic or Non-Ethiopic we used Support Vector Machine (SVM). The datasets are
collected in the ancient Ethiopian Orthodox Tewahedo Church (EOTC and markets that are
found around Bahir Dar Ethiopia. We collected 746 Ethiopic icon images and 721 Non-Ethiopic
icon images with 512x512 image size. From the 1467 icon images 80% dataset to train the
model and 20% dataset to evaluate the performance of the model. Finally to evaluate the
performance of the model we used a Support Vector Machine (SVM) classifier. After evaluating
the model we achieved 90.06%, 86.73%, 84.69%, 85.03%, 92.51%, 93.54%, and 95.24%
accuracy for end-to-end CNN and CNN, HOG, and Gabor, CNN_HOG, CNN_Gabor, and
CNN_HOG_Gabor with an SVM classifier respectively.
