The application of optimal transputer architecture to concurrent processing in the implementation of vision processing algorithms
Repetitive low level image processing transformations can be performed at high speeds by SIMD arrays, DSP and dedicated VLSI devices. These strategies cannot be adppted with more complex and time consuming data dependent algorithms. A flexible and programmable component must be used, and the use of …
