Abstract The study in this thesis was set to present different image segmentation tools that offer very promising approaches in image processing especially for medical imaging that helps in increasing the accuracy of computer aided diagnosing (CAD) systems. Accurate image segmentation will lead to increasing the success rate of detecting the liver cancerous lesions in its early stages for the purpose of treatment or surgery. Accurate segmentation needs integrating many tools and algorithms due to the intensity similarities between the liver tissues and the neighboring organ tissues, also the similarity in intensities of the liver cancer lesions and the liver tissues specially in the early stages of the disease, in addition to the problem of the presence of various lesions in diverged areas of one liver in advanced liver cancer cases. |
