Linear transformation in image processing
Nettettransformation). Algorithms to perform efficient forward and inverse DRT transformation and for primitive translation and rotation in DRT space were presentedin[11]. Nettet6. des. 2015 · Linear transformation includes simple identity and negative transformation. Identity transformation has been discussed in our tutorial of image transformation, but a brief description of this transformation has been given here. Identity transition is shown by a straight line.
