Abstract: Disclosed is a method (100) for correcting artifacts in Optical Coherence Tomography (OCT) images. The method involves acquiring an OCT image and subsequently transforming it from a Cartesian coordinate system to a polar coordinate system via polar reconstruction, generating a reconstructed polar OCT image. This image is then segmented into RED, GREEN, BLUE color channels. Fourier transformation is applied to each channel, transitioning them into their frequency domain representations. A custom frequency mask is utilized on these images, filtering out artifact-related frequencies. Following this, an inverse Fourier transformation is executed, reverting the images back to their Cartesian format. These images are then combined to produce a reconstituted OCT image. Further, this reconstituted image is merged with the original OCT image, resulting in an OCT image that is substantially free from artifacts.

Abstract: Disclosed in the embodiments of the present application are a data storage method and apparatus, a device, and a non-transitory readable storage medium. According to the embodiments of the present application, F parity blocks occupying blank storage areas are added to a RAID system, which not only increases error tolerance but also eliminates the need for additional parity disks. During data storage, corresponding original check codes are solved according to an original encoding method, and additional check codes located on the parity blocks are solved simultaneously. Thus, it is possible to recover more erroneous data based on the original check codes and the additional check codes. When an error occurs in a disk in which any block in a stripe is located and data loss occurs in other blocks of the same stripe, the corresponding data can still be recovered.
