Convert WHITE pixels in a binary image to a given greyscale.

 

function call:

[out_img1]=vsg('BinGrey',in_img1,num1);

 

Arguments:

in_img1 input image, 3 channel RGB, 1 channel greyscale or binary image, or DICOM image.

num1 – an integer or double specifying the output value of input white regions.

 

Description:

Converts a binary image to a user defined grey scale grey.

out_img1 – An image which has dimensions the same as the input image. The output pixel values are set to num1 if the corresponding input pixels are white.

 

Example:

img=openimage('lake.jpg');

h=figure;image(uint8(img));set(h,'Name','Input image');

[out_img1] = vsg('Threshold',img,100);

h=figure; image(uint8(out_img1));set(h,'Name','Threshold image');

[out_img1]=vsg('BinGrey',out_img1,200);

h=figure; image(uint8(out_img1));set(h,'Name','Grey image');

 

Notes:

1. For DICOM images, the function operates on all slices separately.

2. For RGB images, the function operates on all colour planes separately.
