Embodiment 1
[0114] The OCT image layer segmentation method based on random forest and compound activity curve in this embodiment includes:
[0115] like figure 1 As shown, training the OCT image features to train the random forest classifier, when training the random forest classifier, the central serous retinopathy retinal OCT image is divided into 8 regions; region 1: nerve fiber layer; region 2: ganglion cell layer Area 3: inner plexiform layer; area 4: inner core layer; area 5: outer plexiform layer; area 6: outer nuclear layer + outer membrane + sample area; area 7: ellipsoid area + outer photoreceptor node layer + interlaced Area + retinal pigment epithelium / Bruch; area 8 (class 8): vitreous + choroid; the upper surface layer of area 1 Surface1, the upper surface of area 2 Surface2... The upper surface of area 8, Surface1 is referred to as SF1, the same is Surface2 SF2 for short...Surface8 is abbreviated as SF8. For details, see figure 1 shown.

Embodiment 2
[0125] This embodiment is based on the OCT image layer segmentation method of random forest and compound activity curve. On the basis of Embodiment 1, the obtained OCT image feature training random forest classifier specifically includes:
[0126] The central serous retinopathy retinal OCT image was segmented into 8 regions; region 1: nerve fiber layer; region 2: ganglion cell layer; region 3: inner plexiform layer; region 4: inner nuclear layer; region 5: outer plexiform layer layer; area 6: outer nuclear layer + outer membrane + sample area; area 7: ellipsoid area + outer photoreceptor nodal layer + interlaced area + retinal pigment epithelium / Bruch; area 8 (class8): vitreous + choroid; area The upper surface layer of 1, Surface1, the upper surface of area 2, Surface2... The upper surface of area 8, Surface1 is referred to as SF1, and similarly Surface2 is referred to as SF2...Surface8 is referred to as SF8 for details. figure 1 The specific division shown is not limited t...
