detect_stripe
(listdata, snr)[source] Algorithm 4 in the paper. To locate stripe positions.
- Parameters
listdata (1D normalized array.) –
snr (Ratio (>1.0) used to detect stripe locations.) –
- Returns
listmask
- Return type
1D binary mask.
-
pre_process
()[source] This method is called immediately after base_pre_process().
-
process_frames
(data)[source] Apply algorithm 6, 5, and 3 in the paper to removal all types of stripes
-
remove_large_stripe
(matindex, sinogram, snr, size)[source] Algorithm 5 in the paper. To remove large stripes.
- Parameters
sinogram (2D array.) –
snr (Ratio (>1.0) used to detect stripe locations.) –
size (Window size of the median filter.) –
- Returns
sinogram
- Return type
stripe-removed sinogram.
-
remove_stripe_based_sorting
(matindex, sinogram, size)[source] Algorithm 3 in the paper. To remove partial and full stripes.
-
remove_unresponsive_and_fluctuating_stripe
(sinogram, snr, size)[source] Algorithm 6 in the paper. To remove unresponsive and fluctuating stripes.
- Parameters
sinogram (2D array.) –
snr (Ratio (>1.0) used to detect stripe locations.) –
size (Window size of the median filter.) –
- Returns
sinogram
- Return type
stripe-removed sinogram.
-
setup
()[source] This method is first to be called after the plugin has been created. It determines input/output datasets and plugin specific dataset information such as the pattern (e.g. sinogram/projection).
