Add random noise to the input images. Noise can be generated using uniform, gaussian or t-student distributions.
Parameters
--mode <mode
overwrite> where <mode> can be:
-
- $
--label <image_label
image> $-o, --output <output_file
> $--oroot <root
> $--save_metadata_stack <output_md
> $: Store the original image filename in the output metadata in column imageOriginal. $
: Preserve the columns from the input metadata. Some of the column values can be changed by the program. $``: Type of noise to add where <rand_mode> can be: - $
: Crop noise histogram below this value $
: Crop noise histogram above this value
Add noise to a single image, writing in different image:
xmipp_transform_add_noise -i cleanImage.spi --type gaussian 10 5 -o noisyGaussian.spiFollowing
cleanImage.spi
at left andnoisyGaussian.spi
at right: Add uniform noise to a volume, overriding input volume:xmipp_transform_add_noise -i g0ta.vol -uniform -0.1 0.1
