2. Yu-Yun Chou,Yi-Jean Chu 2 Outline Introduction Approach Fuzzy Application Comment fuzzy application

3. Yu-Yun Chou,Yi-Jean Chu 3 Introduction To characterize and categorize of video sequences The characterization of video sequences Frame Based-Dynamic & Static video analyze Mosaic Based-Static video analyze The classification of video sequences Fuzzy Inferencing Examples-Cricket,Golf,Football Mosaic Based-Static video analyze

4. Yu-Yun Chou,Yi-Jean Chu 4 Frame Based Frame based The representation of video in terms of r-frames Original frames Current frameReference frame Original current frame-Encoded previous frame=Motion Vector(MV) Previous frame+MV

5. Yu-Yun Chou,Yi-Jean Chu 5 Mosaic Based Collection of overlapping images To put together with coordinate transforms relating the different image frame Mosaic

6. Yu-Yun Chou,Yi-Jean Chu 6 The classification of video sequences Extraction Content extraction form Mosaics Classification Using fuzzy Inferencing to classify the video sequences

7. Yu-Yun Chou,Yi-Jean Chu 7 Extraction RGB HSI Red,Green,Blue Hue,Saturation,Intensity

8. Yu-Yun Chou,Yi-Jean Chu 8 Classification To classify the video sequences Fuzzy Inferencing Fuzzy Attribute Fuzzy rule

9. Yu-Yun Chou,Yi-Jean Chu 9 Fuzzy Attribute Green Score Counting all the green color pixels having hue value near to 120 degrees Pitch Score Counting the color and the rectangular shape match of the image regions Player Score Counting the elliptical blob surrounded by green grass

10. Yu-Yun Chou,Yi-Jean Chu 10 Fuzzy Set Level Green-Score Small Medium High Pitch-Score Negligible Medium Large Man-Score Single Many

11. Yu-Yun Chou,Yi-Jean Chu 11 Fuzzy Rule AttributeGreen-Score(G);Pitch-Score(P);Man-Score(M) GolfIf (G is high) and (P is negligible) and (M is single) then the match may be a GOLF sequence If (G is medium) and (P is negligible) and (M is single) then the match may be a GOLF sequence FootballIf (G is high) and (P is negligible) and (M is many) then the match may be a FOOTBALL sequence If (G is medium) and (P is negligible) and (M is many) then the match may be a FOOTBALL sequence If (G is small) and (P is negligible) and (M is many) then the match may be a FOOTBALL sequence CricketIf (G is high) and (P is large) and (M is single) then the match may be a CRICKET sequence If (G is high) and (P is large) and (M is many) then the match may be a CRICKET sequence If (G is high) and (P is medium) and (M is single) then the match may be a CRICKET sequence If (G is high) and (P is medium) and (M is many) then the match may be a CRICKET sequence If (G is medium) and (P is large) and (M is many) then the match may be a CRICKET sequence

14. Yu-Yun Chou,Yi-Jean Chu 14 Comment The list of analyzing fuzzy application If not using fuzzy application Complex Classification Hard to computing Advantage Simple Classification Fast computation Disadvantage Increase in error rate The fuzzy application only suitable for extremely different motion
