چکیده

Image data set from a multi-spectral animal imaging system is used to address two issues: (a) registering the oscillation in optical coherence tomography (OCT) images due mouse eye movement and (b) suppressing shadow region under thick vessels/structures. Several classical AI-based algorithms combination are tested for each task see their compatibility with combined system. Hybridization of AI flow followed by Homography transformation shown be working (correlation value>0.7) registration. Resnet50 backbone better than famous U-net model detection loss value 0.9. A simple-to-implement analytical equation brightness manipulation 1% increment mean pixel values 77% decrease number zeros. The proposed allows formulating constraint optimization problem using controlling factor {\alpha} minimization zeros, standard deviation maximizing value. For Layer segmentation, used. AI-Pipeline consists CNN, Optical flow, RCNN, model, models sequence. thickness estimation process has 6% error as compared manual annotated data.

Retinal layer segmentation of macular OCT images using boundary classification

Optical coherence tomography (OCT) has proven to be an essential imaging modality for ophthalmology and is proving to be very important in neurology. OCT enables high resolution imaging of the retina, both at the optic nerve head and the macula. Macular retinal layer thicknesses provide useful diagnostic information and have been shown to correlate well with measures of disease severity in seve...

Multicenter reliability of semiautomatic retinal layer segmentation using OCT

Objective To evaluate the inter-rater reliability of semiautomated segmentation of spectral domain optical coherence tomography (OCT) macular volume scans. Methods Macular OCT volume scans of left eyes from 17 subjects (8 patients with MS and 9 healthy controls) were automatically segmented by Heidelberg Eye Explorer (v1.9.3.0) beta-software (Spectralis Viewing Module v6.0.0.7), followed by m...

Segmentation of retinal OCT images using a random forest classifier

Optical coherence tomography (OCT) has become one of the most common tools for diagnosis of retinal abnormalities. Both retinal morphology and layer thickness can provide important information to aid in the differential diagnosis of these abnormalities. Automatic segmentation methods are essential to providing these thickness measurements since the manual delineation of each layer is cumbersome...

Probabilistic intra-retinal layer segmentation in 3-D OCT images using global shape regularization

With the introduction of spectral-domain optical coherence tomography (OCT), resulting in a significant increase in acquisition speed, the fast and accurate segmentation of 3-D OCT scans has become evermore important. This paper presents a novel probabilistic approach, that models the appearance of retinal layers as well as the global shape variations of layer boundaries. Given an OCT scan, the...

Segmentation of Retinal Nerve Fiber Layer in Optical Coherence Tomography (OCT) Images using Statistical Region Merging Technique for Glaucoma Screening

The Retinal Nerve Fiber Layer thickness is one of the main clinical parameter used to diagnose glaucoma eye disease. The thickness of the RNFL decreases as the intraocular pressure inside the eye increases. Decrease in RNFL thickness or damages to RNFL due to high intraocular pressure leads to Glaucoma. The present work provides a technique for the segmentation of Retinal Nerve Fiber Layer (RNF...
