3 Morphology Image Processing Daniel Novák , Prague Acknowledgments: José Neira Parra
4 Morphology - Morphology deals with form and structure - Mathematical morphology is a tool for extracting image components useful in: representation and description of region shape (e.g. boundaries) pre- or post-processing (filtering, thinning, etc.) - Based on set theory
5 Morphological Image Processing
6 Morphological Image Processing
7 Dilation & Erosion - The value of the output pixel is the maximum value of all the pixels in the input pixel's neighborhood. - Dilation: B is the structuring element in dilation. A B = { x [( Bˆ) x A] A} - The value of the output pixel is the minimum value of all the pixels in the input pixel's neighborhood. - Erosion: A B = { x ( B) A} x

17 Opening & Closing In essence, dilation expands an image and erosion shrinks it. Opening: generally smoothes the contour of an image, breaks isthmuses, eliminates protrusions. Closing: smoothes sections of contours, but it generally fuses breaks, holes, gaps, etc. - Opening of A by structuring element B: Closing: A B = ( A B) A B = ( A B) B B

28 Post-processing - Reduces the width of the ridges to one pixel - Skeletons, spikes - Filling holes, removing small breaks, eliminating bridges between ridges etc. - cleanskeleton: removespur, linkbreak, removebridge
29 Thinning enhance2ridgevalley.m imoutput = bwmorph(imcomplement(imreconstruct),'thin', 'Inf'); %thins the reconstructed image
30 Singularity and Core Detection - Poincare Method
31 Singularity and Core Detection - Poincare Method
32 Singularity and Core Detection - Poincare Method If we know the type of the fingerprint beforehand, false singularities can be eliminated by iteratively smoothing the image with the help of the following observation: Arch fingerprints do not contain singularities Left loop, right loop and tented arch fingerprints contain one loop and one delta Whorl fingerprints contain two loops and two deltas
33 Singularity and Core Detection - Methods based on local features Orientation histograms at local level (3x3) Irregularity Fp1 = findsingularitypoint(fp1); d ij = [r ij.cos2θ ij, r ij sin2 θ ij ]
34 Singularity and Core Detection - Partitioning based methods
35 Feature Extraction
36 Feature Extraction Errors
37 Non-linear distortion
38 Intra-variability
39 Fingerprint matching
40 MATCHING: Approaches - Correlation-based matching Superimpose images compare pixels - Minutiae-based matching Classical Technique Most popular Compare extracted minutiae - Ridge Feature-based matching Compare the structures of the ridges Everything else
41 Fingerprint Matching - Compare two given fingerprints T,I Return degree of similarity (0->1) Binary Yes/No - T -> template, acquired during enrollment - I -> Input - Either input images, or feature vectors (minutiae) extracted from them - Pressure and Skin condition Pressure, dryness, disease, sweat, dirt, grease, humidity - Noise Dirt on the sensor - Feature Extraction Errors - Many algorithms match high quality images - Challenge is in low-quality and partial matches - 20% of the problems (low quality) at FVC2000 caused 80% of the false non-matches - Many were correctly identified at FVC2002 though
42 Correlation-based Techniques - T and I are images - Sum of squared Differences SSD(T,I) = T-I 2 = (T-I) T (T-I) = T 2 + I 2 2T T I Difference between pixels - T 2 + I 2 are constant under transformation - Try to maximize correlation Minimizes difference CC(T,I) = T T I Can't be used because of displacement / rotation - I (Δx,Δy,θ) Maximizing Correlation Transformation of I Rotation around the origin by θ Translation by x,y - S(T,I) = max CC(T,I (Δx,Δy,θ) ) Try them all take max
43 Correlation Results
44 Minutiae-based Methods - Classical Technique - T, I are feature vectors of minutiae - Minutiae = (x,y,θ) - Two minutiae match if Euclidean distance < r 0 Difference between angles < θ 0 Tolerance Boxes - r 0 - θ 0
45 Formulation - M'' j = map(m' j ) Map applies a geometrical transformation - mm(m'' j, m i ) returns 1 if they match - Matching can be formulated as - P is an unknown function which pairs the minutiae Which minutiae in I corresponds to which in T: allign2
