Linear transformation image processing
NettetIn the context of solving linear equations we have introduced the notion of a vector and a matrix. The result is a compact notation for representing linear equations, A~x =~b. Multiplying both sides by the matrix inverse A−1 yields the desired solution to the linear equations: A−1A~x = A−1~b I~x = A−1~b ~x = A−1~b (23) NettetChapter 24: Linear Image Processing. Linear image processing is based on the same two techniques as conventional DSP: convolution and Fourier analysis.Convolution is …

NettetB = imwarp (A,tform) transforms the numeric, logical, or categorical image A according to the geometric transformation tform. The function returns the transformed image in B. B = imwarp (A,D) transforms image A according to the displacement field D.

Linear image processing is based on the same two techniques as conventional DSP: convolution and Fourier analysis. Convolution is the more important of these two, since images have their information encoded in the spatial domain rather than the frequency domain. Linear filtering can improve images in many ...
