چکیده

Edge detection is a very important preprocess for image processing research, we can decide the information about position, contours or size of the object by the features of image edge that detected by edge detection, and approach of pattern recognition and information retrial. But in general the edge detection methods, are required to manually select the parameters of an ideal edge to detect the edge, this method is not efficient. This study used special gray-level conversion and Crimmins Speckle Removal as pre-treatment, and use of the Contextual-Hopfield Neural Network methods to unsupervised-learning methods to solve the problem manually select the parameters. Finally the use of voting to select the ideal edge imaging tests to assess the parameters of this study without the accuracy. The experiment proved that the method of unsupervised detection results can be similar to the edge of the ideal results.

Contextual Hopfield Neural Networks for Medical Image Edge Detection

Outlining of boundaries of organs and tumors in CT and MRI images are prerequisite in medical applications. In this paper, a single layer Hopfield neural network called Contextual Hopfield Neural Network (CHNN) is presented for finding the edges of CT and MRI images. Different from the conventional 2-D Hopfield neural networks, the CHNN maps the two-dimensional Hopfield network at the original ...

Comparison of Hopfield Neural Network and Fuzzy Clustering in Segmenting Sputum Color Images for Lung Cancer Diagnosis

The analysis of sputum taken from patients can be an extremely valuable technique for an early detection diagnosis of lung cancer. There is a great need for an automated system which can provide accurate analysis of the morphology of the sputum cells on a microscope slide, or diagnose their color digital image using special software. In this work, we compare two unsupervised segmentation method...
