Constructing Benchmark Databases and Protocols for Medical Image Analysis: Diabetic Retinopathy

Algorithm 3

Strawman algorithm.

(1) Extract colour information (𝑟,𝑔,𝑏) of the lesion from the train set images (Section 3.4).

(2) Estimate 𝑝(𝑟,𝑔,𝑏∣lesion) from the extracted color information using a Gaussian

  mixture model determined by using the Figueiredo-Jain method [15, 16].

(3) Compute 𝑝(𝑟,𝑔,𝑏∣lesion) for every pixel in the test image (repeat step for every

  test image in the test set).

(4) Evaluate the performance (Section 4).
