Application: Image processing method, image processing apparatus, and recording medium (Patent ID: US20230419451A1)
The patent filed by Topcon Corp describes a method for processing optical coherence tomography (OCT) images to reduce birefringence-derived artifacts. The method involves acquiring multiple images using different polarization conditions and then generating a mean image by averaging these images to reduce artifacts. The averaging process includes summation averaging to create an arithmetic mean image with reduced birefringence-derived artifacts and speckle noise. Additionally, the patent discusses the use of machine learning to generate a model based on the arithmetic mean image for further artifact reduction.
Furthermore, the patent details the use of redundant data collection techniques in OCT scans to improve image quality. This includes using intersecting partial patterns or repeating scans targeting the same region of the sample. The patent also describes an apparatus for processing OCT images, which includes an image acquiring unit with an OCT scanner and a processor for generating the mean image with reduced artifacts. Additionally, a computer-readable recording medium containing a program for processing OCT images is discussed, which involves acquiring images with different polarization conditions and generating a mean image to reduce birefringence-derived artifacts. Overall, the patent presents a comprehensive method and system for improving the quality of OCT images through polarization-based processing and averaging techniques.
