Automated detection of nerve fiber layer defects on retinal fundus images using fully convolutional network for early diagnosis of glaucoma
Method : NFLD 分割
Dataset: Tajimi
Architecture: FCN-8s
Results: 最高 SE 98% , FP (5.42)
automated scheme for detection of a retinal nerve fiber layer defect(NFLD)
Method
Previous study
- multi-step detection : Gabor filtering , clustering and adaptive thresholding
- Problem :FP 多,method included too many rules
Deep convolutional neural network with fully convolutional layers
- end-to-end : DCNN ( FCN-8s)
- image
- Original color images ofabnormal cases,
- (b) original color images of both normal and abnormal cases,
- © ellipse-based polar transformed colorimages,
- (d) transformed G plane images,
- (e) transformed Gabor filtered color images,
- (f) transformed color halved images,
-
(g) transformed color halved images with different data augmentation.
rotation and intensity transformation for all
- add a softmax layer
Result
- 使用 normal and abnormal image 减少了 FP 但是也降低了 SE
- 虽然 绿色通道 对比度更高,但是用RGB图具有更高的灵敏度
- DCNN 通用性比 previous study 更好
- FROC ,最高SE 98% , FP (5.42)
Discussion
- 研究了 不同输入图像 ,结果的不同,主要是从输入数据这块 做了一些对比实验(个人感觉含金量不高)
- 研究了 FCN 在 眼底图中自动检测 NFLDs的应用
