AB The automatic location of the fovea is very useful for diagnosing retinal diseases. It isa complex problem for which diferent solutions have been proposed based on classicalimage processing and Deep Learning techniques. The method presented in this paper isbased on histograms that combine spatial and color information in such a way that thespatial coordinates are incorporated into conventional color histograms as an additionaldimension. The binarization of these histograms retains a considerable amount of relevantinformation from the original image, allowing them to be processed as if they were ordinary images. This approach to the problem results in a simple, fast and efective method forlocating the fovea. Diferent experiments have been carried out with three popular sets ofimages: Messidor, REFUGE1 and DIARETDB1, and a comparison was made with otherstate-of-the-art techniques. Our results show that the proposed method, despite its simplicity, is capable of surpassing many of these techniques.
