background extraction always uses all frames

[mihsamusev]

Independent on the "Frame count box" in background tab background subtraction uses all the original frames for background extraction, even though the extractor is initialized with the correct desired frame count:

	def extractBackground(self, method, **kwargs):
	self.bg_extractor = BackgroundExtractor(**kwargs)
	self.bg_extractor.extract(self._originalFrames)
	self.originalBgFrame = self.bg_extractor.get_background()

Lines 17 to 24 in c75c11d

	def extract(self, frames):
	rangeImgs = []
	newSizes = []
	# Prepare range images
	for f in frames:
	newSize, rangeImg = self.reshape2scanlines(f.distance)
	rangeImgs.append(rangeImg)
	newSizes.append(newSize[0])
