PCNN has rapidly developed as a new tape of artificial neural network since 90s of the 20th century. PCNN's neuron model is an artificial neural model obtained by simulating visual neural activity, so this neural network model has biology research background. Due to in the environment of weak connection, PCNN has the features as scale invariance, rotation invariant, signal strength invariance, signal distortion invariant and especially it can change two-dimensional spatial variables into one-dimensional tim...
