The presence of yawning would be indicated by a black blob in the mouth region of the binary image. The features extracted for yawning detection are the histogram values taken from the vertical projection The occlusions on the driver's face may be many, such as mouth covered by hand while yawning; wearing As per the assumptions made in section 3.2, the proposed system detects yawning when the driver's face is 	./cache/work_o6apwsmoubhl7pn66lgybiegnu.pdf	./txt/work_o6apwsmoubhl7pn66lgybiegnu.txt
