Adaptive Thresholding Technique for Retinal Vessel Segmentation Based on GLCM-Energy Information

Figure 10

Adaptive thresholding using different ASM range information on STARE database. (a) STARE database ground truth. (b) Segmented retinal vessel by Hoover [4]. (c) Segmented vessel through adaptive thresholding using minimum ASM mid-range threshold value for the grayscale intensity image. (d) Segmented vessel through adaptive thresholding using maximum ASM mid-range threshold value for the grayscale intensity image. (e) Segmented vessel through adaptive thresholding using mean ASM mid-range threshold value for the grayscale intensity image. (f) Segmented vessel through adaptive thresholding using minimum ASM mid-range threshold value for the Green Channel. (g) Segmented vessel through adaptive thresholding using maximum ASM mid-range threshold value for the Green Channel. (h) Segmented vessel through adaptive thresholding using mean ASM mid-range threshold value for the Green Channel.
