BUT I CAN SHOW YOU THAT MATHS IS IMPORTANT IN CRIME DETECTION MEDICINE FINDING LANDMINES AND MANY OTHER CAREERS!!!!!!!!! Slide 3: Maths and crime: Deblurring a number plate A short crime story Burglar robs a bank Escapes in a getaway car Pursued by police Nasa Slide 4: GOOD NEWS Police take a photo BAD NEWS Photo is blurred Slide 5: SOLUTION Find a model of the blurring process Original image f Blurred image h Blurring formula Inverting the formula we can get rid the blur BUT need to know the blurring function g Blurring function g Slide 6: An example of Image Processing Inversion formula h(x) f(x) Maths is widely used in the forensic service!! Slide 7: HOW MATHS WILL GET YOU ON TV PICTURES AND IMAGES ARE ALL AROUND US TV DVD COMPUTER GRAPHICS SPECIAL EFFECTS IMAGES ARE STORED AS NUMBERS USING THESE NUMBERS WE CAN PROCESS THE PICTURES BY USING MATHEMATICS Slide 8: SOME APPLICATIONS PRODUCING THE PICTURES IN THE FIRST PLACE TRANSMITTING THE PICTURES WITHOUT MISTAKES Lots of mathematicians work in IT and mobile phone companies Galois Lots of mathematicians work in computer graphics, computer games and Hollywood Slide 9: MATHS AND MEDICINE Modern medicine has been transformed by methods of seeing Inside you without cutting you open! Ultra sound: sound waves MRI: magnetism CAT scans: X rays ALL USE MATHS TO WORK!! Slide 10: Modern CAT scanner CAT scanners work by casting many shadows with X-rays and using maths to assemble these into a picture Lots of mathematicians work in medicine Slide 11: Some interesting mathematical facts Over 70% of all jobs require maths On average maths graduates earn more than any other profession Many degrees require maths including statistics, physics, engineering, economics, chemistry, medicine, IT, computer games, computer science, social-science, psychology, fashion design, business studies, accountancy, actuarial studies, electronics, aeronautics, cryptography, .. Without maths we would have no TV, mobile phones, Internet, credit cards, computer games, CDs, Radar, aeroplanes, DNA profiling, … Maths is vital working out your mortgage payments, APR calculations, family budget Florence Nightingale was a mathematician Slide 13: FINALE: USING MATHS TO FIND ANTI-PERSONEL LAND MINES Land mines are hidden in foliage and triggered by trip wires Land mines are well hidden .. we can use maths to find them Slide 14: Find the trip wires in this picture Slide 15: Digital picture of foliage is taken by camera on a long pole Image intensity f(x,y) • • • • Trip wires are like X-Rays Radon transform x y f(x,y) R(ρ,θ) Points of high intensity in R correspond to trip wires θ ρ Isolate points and transform back to find the wires Slide 16: Mathematics finds the land mines!
