Abstract
A laser scanning ophthalmoscope obtains images of a retina. An image is processed by (i) mapping an image along a one dimensional slice; (ii) computing a wavelet scalogram of the slice; (iii) mapping ridge features from the wavelet scalogram; repeating steps (i), (ii) and (iii) for one or more mapped image slices. The mapped ridge features from the slices are superimposed. Textural information is derived from the superimposed mapped ridge features. The analysis can be tuned to detect various textural features, for example to detect image artifacts, or for retinal pathology classification.
