Abstract
The concept of overlapped block digital filtering is extended to two-dimensional (2D) case. The shift-invariant conditions of 2D overlapped block digital filters are derived. Fast algorithms based on short-length linear convolution algorithms and DFT are then derived. These algorithms are computationally efficient and highly parallel.
