Removing labels in scikit-image

I have labeled an binary image enter image description here

imageLabels = morphology.label(imageBinary, background=255)

However when I check the number of labels, I get 535 elements. 

print(len(imageLabels))

As a solution for this I thought about using measure.regionprops in order to remove the labels with a small pixel area. How would you guys approach this? I have tried the following, but for one reason or another the new array is no longer seen as a correct label element.

i=0
for labelprop in measure.regionprops(imageLabels):
    if (labelprop.area > 100):
        imageLabels_keep.append(imageLabels[i])
    i=i+1

I think morphology.remove_small_objects(image, min_px_size) does what you're looking for. Here's an example that uses that function:
