Sets all pixels of the input image which are less than the specified
threshold to black.
function call:
[out_img1]=vsg('GSCapThresh',in_img1,num1);
Arguments:
in_img1
input image, 3 channel
num1
– an integer or double specifying the threshold for the greyscale cap
threshold function.
Description:
out_img1
– An image which has dimensions the same as the input image. The output
pixel values are the input pixel values if they are larger than num1,
otherwise they are black.
Example:
img=openimage('crown.jpg');
h=figure;image(uint8(img));set(h,'Name','Input
image');
[out_img1]=vsg('GSCapThresh',img,100);
h=figure;image(uint8(out_img1));set(h,'Name','GSCapThresh');
Notes:
1. For DICOM images,
the function operates on all slices separately.
2. For
