Data Independent Karhunen-Loéve Transform for Image and Video Coding

Transform coding plays an important role in image and video compression. The Karhunen-Loéve transform (KLT) is the optimal transform for its full decorrelation ability. However, there is no general algorithm that enables its fast computation since the KLT is data dependent. Instead, the discrete cos...
