Automated Counting Axons in Optic Nerves using Hough Transformation

چکیده

I developed an algorithm to count the number of axons in optic nerves automatically using Hough Transformation to detect axon edges. Due to the low quality of nerve images, a pre-process is required using Gaussian filter.

Quantifying optic nerve axons in a cat glaucoma model by a semi-automated targeted counting method

PURPOSE To describe and validate a semi-automated targeted sampling (SATS) method for quantifying optic nerve axons in a feline glaucoma model. METHODS Optic nerve cross sections were obtained from 15 cats, nine with mild to severe glaucoma and six with normal eyes. Optic nerves were dissected, fixed in paraformaldehyde and glutaraldehyde, and processed for light microscopy by resin embedding...

A Hole-filling Algorithm for Automated Axon Counting

This paper presents an algorithm for the automated counting of axons in microscope images of cross-sections of the optic nerve. The approach uses a hole-filling algorithm to identify closed bundles in the image. Six images in which axons were labeled by a trained observer (TO) were used as test data for the algorithm. Results show that the algorithm counted the axons with an average relative er...

Histomorphogenesis of cranial nerves in Huso huso larvae

In this study the cranial nerves development of H. huso are explained from 1 to 54-days-old (1, 3, 6, 15, 21 and 54 days). Despite all the researches on fish brain, there are no study on nerves evolution on H. huso during their larvae life. For this research 40 samples of larvae H. husowere obtained (from each age, about six samples were selected). The specimens were ...

GABA Immunopositive axons in the optic nerve and optic tract of Macaque Monkeys

Using an antibody to gamma-aminobutyric acid (GABA), we examined the optic nerves and optic tracts from macaque monkeys at the light and electron microscopic levels to determine if there is a possible inhibitory projection from the retina to the brain. All of the monkeys (n = 5) had GABA immunopositive axons that were evenly distributed in their optic nerves. These immunopositive axons were sli...

The number and diameter distribution of axons in the monkey optic nerve.

Using an automated image analysis system, cross-sections from optic nerves of 17 normal cynomolgus monkeys were examined. The number of nerve fibers, their density, and the distribution of their diameters for whole nerves and for various regions of the nerve cross-section were estimated. The mean total number of fibers in the optic nerve was 1.2 million. The mean diameter of axons was 0.8 micro...
