Abstract
In this article, we construct two-dimensional continuous/smooth local sinusoidal bases (also called Malvar wavelets) defined on L-shaped reg ions. With this construction, one is able to construct local sinusoida l bases and lapped orthogonal transforms (LOT) on arbitrarily shaped r egions. This work is motivated from and useful in object-based video c oding, where a segmented moving object may have arbitrary shape and bl ock transform coding of this object is needed.
