ENAI 400 AUDIO AND IMAGE PROCESSING
This course deals with the digital processing of audio and image signals in time and frequency domains. The course covers the following topics:
Audio Concepts: audio transducers, analogue and digital audio signals, oversampling techniques, storage media
Audio Analysis: time and frequency domain, spectrograph
Audio Filtering: noise enhancement, special audio effects, echo, reverberation
Image Concepts: capturing devices, output devices, display systems, printers
Image Representation: spatial domain analysis, RGB, CMYK and Ycbcr, frequency domain analysis, 2D FFT and DCT
Image Interpolation: bilinear, bicubic, image assessment techniques
2D Filtering: FIR filters, smoothing and sharpening filters, edge detectors, median filters
Image Enhancement: Brightness and contrast improvement, color adjustment, noise smoothing
Image Restoration: image degradation, additive and multiplicative noise, Wiener filters, blurring, inverse filtering
Image Segmentations: point and line algorithms, thresholding, growing techniques
Image watermarking: robust and fragile watermarking, transform domain techniques
