A digit-serial architecture for gray-scale morphological filtering
L. Lucke, Chaitali Chakrabarti · IEEE Transactions on Image Processing · 1995
We present a digit-serial architecture for gray-scale morphological operations that operate on radix-2 redundant numbers. We present new implementations for a redundant number adder and a maximum unit that are used in the morphological dilation unit. These new designs have areas comparable to 2's complement implementations but have significantly smaller latencies.
