WebNow, assuming that you want to modify one of those mentioned coefficients, you need to be familiar with the usage of wavedec2. This function puts all coefficients one after the other in one row. Here is my post about working with MATLAB's wavelet toolbox. "Example 5" demonstrates how wavedec2 stores coefficients. WebWhen X represents an indexed image, X, as well as the output arrays cA,cH,cV, and cD are m-by-n matrices. When X represents a truecolor image, it is an m-by-n-by-3 array, where each m-by-n matrix represents a red, green, or blue color plane concatenated along the third dimension. The size of vector C and the size of matrix S depend on the type of analyzed …
