Syntax: maskedmean(input image, output image, ignored value, print to log, square root)

Calculates mean of all pixels in the input image, but skips specific value in the calculation. The output is a 1x1x1 image.

This command can be used in the distributed processing mode. Use distribute command to change processing mode from local to distributed.

## Arguments¶

### input image [input]¶

Data type: uint8 image, uint16 image, uint32 image, uint64 image, int8 image, int16 image, int32 image, int64 image, float32 image

Input image.

### output image [output]¶

Data type: float32 image

Output image.

### ignored value [input]¶

Data type: real

This value is ignored in the calculation.

### square root [input]¶

Data type: boolean

Default value: False

Set to true to take square root of the pixel values before calculating mean. This is a hack currently needed in distributed thickness map calculation. If set to true, the input image will contain its square root at output, except in distributed processing where it will retain its old value.
