Job: Local Filtering

Locally filter a refined map.

Description

Locally filter a refined map using a local resolution map. The Local Filtering job can:

• filter an input volume using a spatially adaptive filter, either using a lanczos (default) or gaussian kernel

• optionally apply global sharpening via a B-factor

• Run on the GPU (default) or CPU

• optionally filter only within a mask_refine input that is connected, to save time

The job is designed to work with the output of the Local Resolution Estimation job.

Input

• a single volume input containing

  • map_half_A

  • map_half_B

  • map_locres

  • mask_refine (optional)

Output

• a single volume output containing

  • map_filtered , the locally filtered, globally sharpened output map

Common Parameters

• B-factor for sharpening should be set to a negative value to sharpen

• Maximum resolution for sharpening should be set to a cutoff resolution to ensure that very high resolution Fourier components do not get over-sharpening resulting in a noisy output
