Abstract
A method for carrying out morphic transformations with minimal memory accesses by using a two step convolving sequence to form an intermediate image. The components of the intermediate image are used in a recursive process to provide the desired final convolution. The word resulting from this convolution is then used to access a morphic transformation table in a second memory access for table hookup. The two step convolution requires a total of only two memory reads and two memory writes.
