Improved Covering Blanket method for Choroidal Neovascularization (CNV) texture quantification

The proliferation of blood vessels originating from the choroid area causing a rupture in the Bruch membrane hooked on the sub-retinal pigment epithelium (sub-RPE) leads to Choroidal Neovascularization (CNV). The need for texture analysis and quantification rises due to the prediction of prevalence of CNV in near future. Improvement to conventional Covering Blanket method gave us better results for both fractal features; Fractal dimension and fractal signature. Most important of all is that the end results are obtained are superior for ε=4. This decrement in ε iteration gives efficient time complexity with respect to existing solution by Blanket method. Image dataset of about 15 subjects is used for textural quantification of 43 images; supplied by two ophthalmologists. The obtained results show high accuracy with discrimination rate of 98% using Blanket method within less ε iteration.
