BWREMOVE Removes objects in binary image.
BW3 = BWREMOVE(BW1,BW2) returns a binary image BW3 where the objects from the mask image that overlap the seed image are removed. Both the seed BW1 and the mask BW2 images can have multiple blobs.
[BW3, BW4] = BWREMOVE(BW1,BW2) returns the binary image BW4 which contains the removed blob(s).
The input images BW1 and BW2 can be logical or any numeric type and must be 2-D and nonsparse. The output images BW3 and BW4 are logical.
BW1 = imread('text.png');
BW2 = zeros(size(BW1));
BW2(34,126) = 1;
BW3 = bwremove(BW1,BW2);
