Python split_filter Beispiele

Beispiel #1

Datei: test_gen_violajones_opt.py Projekt: visionsystems/BLIP

def test_split_filter_invalid_blocksize():
	''' test blocksize argument handling '''
	h = HaarFeature([((0, 0, 5, 5), -1)], False, 0.01, 0.2, 0.8)
	try:
		res = gen_code.split_filter(h, (1,1), (4,5)) # blocksizes for w and h should be equal
	except InvalidBlocksizeException:
		assert True # this exception should be raised
		return
	assert False # should never get here

Beispiel #2

	''' test correctness of split_filter '''

	ref = [((0, 0, 3, 3), -1), ((0, 3, 3, 2), -1), ((3, 0, 2, 3), -1), ((3, 3, 2, 2), -1)]
