BRAVIITHI ® is a sanskrit word which means “prediction”. BRAVIITHI ®’s mission is to detect diabetic retinopathy at an early stage, preventing the vision loss. Our software suite OKIO is named after “Occhio”, (eye in Italian).
OKIO is a powerful tool that makes use of innate characteristics of different features in the retina pre and post disease onset. We modelled them accordingly using shape, size, color, intensity, density, orientation and compactness attributes.
OKIO not only facilitates early diagnosis, but also provides sufficient information in discriminating artifacts, self-evaluating its predictions. We believe our tool fits these criteria and can have a significant impact on diabetic retinopathy disease handling standards globally.
In addition, OKIO has the capability of performing image quality assessment, thereby advising end-users of potential artifacts present in the image. OKIO suite is designed using simple and powerful mathematical concepts in image analysis, which preserve the innate knowledge source of the retinopathy specialization domain.
