At the beginning the subject describes a principle of imaging systems using transfer functions. Image sensor can be seen also as an imaging system and this subject includes description of various types of image sensors. A signal generated by sensor could be processed by several statistical methods. Interest of this subject lies in the area of wavelet transform utilization and multidimensional signal modeling. Hence, there will be mentioned several denoising methods based on thresholding of wavelet coefficients and image compression algorithms will be chosen. Above mentioned algorithms and principles will be practised on real image data in MATLAB.
