Title:
METHOD AND DEVICE FOR QUICKLY DIVIDING OPTICAL COHERENCE TOMOGRAPHY IMAGE
Document Type and Number:
WIPO Patent Application WO/2020/140380
Kind Code:
A1
Abstract:
A method and device for quickly dividing an optical coherence tomography image, a computer device, and a computer-readable storage medium. The method for quickly dividing an optical coherence tomography image comprises: extracting from pixels of the optical coherence tomography image eigenvalues related to the pixels to acquire the eigenvalues representing the features of the pixels (202), the extracted eigenvalues comprising at least one of an intensity gradient of the pixels, a multiscale intensity mean of the pixels, and an angle eigenvalue extracted from the pixels; inputting the extracted eigenvalues into a Sparse Bayesian classification model comprising relevant values of boundary-corresponding image eigenvalues, and acquiring probability data of the image eigenvalues being pertinent to boundary features of different image areas (204); and acquiring, on the basis of the acquired probability data of different pixels in a set image area, the boundaries of the different image areas that the set image area comprises (206).
