I have a segmented image, it looks like this:
and I would like to further filter out some parts of the image by "excluding" the segments in the image that do not fit certain dimensions (I have the certain dimensions figured out already). How can I change the values of these segments that I would like exclude to 0 instead of 1?

An image is just a matrix in MATLAB. If you know the rows and columns in your image that correspond to segments you want to zero out, then use the colon notation to set portions of the matrix to zero:
A(rowStart:rowEnd,colStart:colEnd) = 0
