Table 2 Comparison of image homogeneity of different age group before and after the anisotropic diffusion processing

From: An artifacts removal post-processing for epiphyseal region-of-interest (EROI) localization in automated bone age assessment (BAA)

  1. This table tabulates the homogeneity value of hand radiograph before and after the anisotropic diffusion. 100 test images are chosen: the test image chosen randomly from each group age of children with different shapes and sizes. The homogeneity is based on the gray level co-occurrence matrix; it illustrates the texture of the resultant image: higher value indicates higher degree of smoothness and vice versa.
