    Sammanfattning : Context- Vision is one of the five elementary physiologial senses. Vision is enabled via the eye, a very delicate sense organ which is highly susceptible to damage which results in loss of vision. The damage comes in the form of injuries or diseases such as diabetic retinopathy and glaucoma. LÄS MER

  7. 5. Detection of Pathological Lesions in High Resolution Retinal Images

    Master-uppsats, Tekniska högskolan; Medicinsk informatik

    Författare :Frida Rosander; [2013]
    Nyckelord :;

    Sammanfattning : High resolution retinal cameras with adaptive optics makes it possible to image small structures in the eye, such as photoreceptors and nerve bres, as well as blood vessels. Adaptive optics was rst developed to reduce blur in stellar images, but has later been used to correct for ocular aberrations in order to achieved higher resolution in retinal images. LÄS MER
