A new automatic parameter setting method of a simplified PCNN for image segmentation

, : A new automatic parameter setting method of a simplified PCNN for image segmentation. IEEE Transactions on Neural Networks 22(6): 880-892

An automatic parameter setting method of a simplified pulse coupled neural network (SPCNN) is proposed here. Our method successfully determines all the adjustable parameters in SPCNN and does not need any training and trials as required by previous methods. In order to achieve this goal, we try to derive the general formulae of dynamic threshold and internal activity of the SPCNN according to the dynamic properties of neurons, and then deduce the sub-intensity range expression of each segment based on the general formulae. Besides, we extract information from an input image, such as the standard deviation and the optimal histogram threshold of the image, and attempt to build a direct relation between the dynamic properties of neurons and the static properties of each input image. Finally, the experimental segmentation results of the gray natural images from the Berkeley Segmentation Dataset, rather than synthetic images, prove the validity and efficiency of our proposed automatic parameter setting method of SPCNN.

Muscle atrophy in catabolic conditions (e.g., diabetes, kidney failure) results from accelerated protein degradation (PD) by the ubiquitin-proteasome (Ub-P) system. Insulin resistance may be a signal for increased PD because: 1) insulin suppresses...
