Blood vessels in ocular fundus are the only one to be observed from outside human body. Screening fundus examination has a beneficial effect on early detection of diseases such as glaucoma. Ophthalmologists observe blood vessels, retina and optic disk in fundus images to diagnose the diseases. Our purpose is to develop a computer-aided diagnosis (CAD) system to detect abnormalities in color retinal images. The shape of optic disk is known and used to assess the progress of glaucoma. In this study, a new method of automatic extraction of optic disk and blood vessels in color retinal images is proposed. The blood vessels were extracted by using mathematical morphology operator from the green component of the RGB value of color retinal images. Next, the blood vessels were erased from the image and then erased pixels were interpolated by using the RGB values of pixels in surrounding region. The optic disk was located by P-tile method with the blood vessels erased image. Moreover, creation of the pseudo stereogram was attempted using the region extracted by the each extraction processing. |
