component analysis (MCA) algorithm is presented inthis paper. MCA was developed based on sparse representation of signals. This algorithmassumes that each signal is a linear combination of several morphologically distinct compo-nents. In the proposed method...

quality assessment. Thenovelty of the proposed method lies in the use of Morphological Component Analysis (MCA) algorithmto discriminate between normal and pathological retinal structures. To this end, first a pre-screeningalgorithm is used to assess...

of Morphological Component Analysis (MCA) algorithm to separate lesions from

normal retinal structures to facilitate the detection process. In the first stage, vessels are

separated from lesions using the MCA algorithm with appropriate dictionaries...
