sharpness_estimate
Estimate image sharpness based on median gradient magnitude.
sharpness_estimate [options] <input>
DESCRIPTION
sharpness_estimate estimates the sharpness of a MINC volume by computing the median gradient magnitude across the image. Higher values indicate sharper images with well-defined edges, while lower values indicate blurry images. This metric is useful for quality control of MRI acquisitions and for evaluating the effects of denoising or blurring operations.
OPTIONS
--maskmask- Restrict the sharpness computation to voxels within the specified binary mask.
EXAMPLES
Estimate sharpness of a T1 volume:
sharpness_estimate t1.mnc
Estimate sharpness within a brain mask:
sharpness_estimate --mask brainmask.mnc t1.mnc
