Nettet17. mar. 2024 · Point processing in spatial domain. All the processing done on the pixel values. Point processing operations take the form –. s = T ( r ) Here, T is referred to as a grey level transformation function or a point processing operation, s refers to the processed image pixel value and r refers to the original image pixel value. 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)
