Abstract

The invention discloses an OCT blood vessel image dislocation correction method. The method comprises the steps of preprocessing blood vessels; performing shift correction on an image based on a Fourier formula and a Euclidean distance transformation formula; and removing noise through a coherent denoising method. Dislocation correction is carried out on a blood vessel image, related noise is suppressed, the quality of retinal blood vessel imaging data is improved, and the correction algorithm is high in efficiency, excellent in image quality, high in robustness and high in efficiency; the method can be used for blood vessel image dislocation correction.

Description

technical field [0001] The invention relates to the technical field of optical image processing, in particular to a method for correcting OCT blood vessel image misalignment. Background technique [0002] In the field of medicine and biological research, the pathological mechanism of many microvascular function parameters is often studied, and the clinical diagnosis is made through the characteristics of microvessels. Medical images are widely used in medical diagnosis as an important auxiliary tool for analyzing the pathological mechanism of microvascular function parameters. However, medical image processing and analysis has always been a research hotspot and difficulty in the field of digital image processing, and the slow development of medical image research has become an important factor restricting the development of medicine. [0003] With the growth of the population base, the sharp transformation of the population structure towards aging, and the widespread use of...
