read.image {SAFARI}

Read a Binary Image

Description

This function reads a reconstructed binary image, possibly, produced from an X-Ray, CT scan, MRI, etc. and processed by standard image processing algorithms. The image is then preprocessed to facilitate the procedure in the binary.segmentation function.

Usage

read.image(file, invert = FALSE)

Arguments

file

a character string that specifies the image to read.

invert

a logical value that indicates if the B/W colors should be inverted.

Details

The binary image is preprocessed as follows:

• Check if image contains multiple color channels, non-binary, or empty.

• Invert black and white colors (optional).

• Ensure image is truly binary by converting all values greater than zero to 1.

• Expand the border around the image with 0s.

• Rotating the image, if it is not stored as an RData file.

Value

An integer matrix that represents the preprocessed image.
