In order to improve the citrus grading accuracy, fractal dimensions which characterize the color and shape features of citrus fruit were analyzed. Samples were from Citrus unshiu Marc.cv.unbergii Nakai. For each sample, images from peduncle, calyx and two opposite sides were collected. These four images were cut, removed backgrounds, and converted from RGB space to HSI one, then by the following methods,...
Extension neural network is a new method based on Extenics and neural networks, it is full use of the Extension of qualitative and quantitative description of the advantages, but also consider the parallel structure characteristics, of neural network. This article describes the extension theory and neural network fusion extension neural network structure and introduce ENN algorithm based on genetic...
To discuss application value of BP neural network to recognizing gastric cancer cell. Object and Method: 510 cells are selected from 308 patients, in which 210 gastric adenocarcinoma cells and 300 non-cancer gastric cells are extracted. Ten morphological parameters of every cell are measured. These data are randomly divided into two groups-training data (A) and test data (B). A three-layer BP neural...
