Image acquisition and processing

• Introduction: examples of application of the image processing from several domains, medical applications, industry, HCI...
• Human vision fundamentals 
• Acquisition
• Definitions : the image processing chain
• Quantification : spatial, spectral and intensity color representation different acquisition modalities sensor,sensor+source,...
• Acquisition devices : CCD, CMOS, vidicon ultrasound light time-of-flight (TOF)
• Notions of compression : run-length-coding, hierarchical decomposition, Jpeg lossy compression
• Pre-processing - Histogram based image enhancement
• Linear filtering Fourier transform
• Fourier domain processing : e.g. interlaced image correction pattern matching
• Image restoration : Wiener filtering rank filter
• Morphomatematics definitions : ensemble, structuring element
• Basic operators : erosion, dilation, duality combined operators : opening, closing
• Hit-or-miss operator thinning and opening : skeleton, pruning,...
• Gray-level morphology watershed transform
• Segmentation/ object detection pixel based : threshold : optimal, Otsu
• Color segmentation border based: gradient, Laplacian, LoG
• Region based : split and merge, watershed(recall) mean-shift
• Hough transform
• Object description binary, image labelling, chain code, polygonal approximation, Fourier descriptors, invariant moments, convexity, fractal dimension, texture

Become familiar with basic numerical image processing

• be able to recognize image properties
• to apply basic filtering and denoising
• to segment an image using classical methods
• theoretical and practical skills are expected.
