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