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

--mask mask
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
