So far, analysis and classification of urine cells number has become an important topic for medical diagnosis of some diseases. Therefore, in this study, we suggest a new technique based on Adaptive Discrete Wavelet Entropy Energy and Neural Network Classifier (ADWEENN) for Recognition of Urine Cells from Microscopic Images Independent of Rotation and Scaling. Some digital image processing methods such as noise reduction, contrast enhancement, segmentation, and morphological process are used for feature extraction stage of this ADWEENN in this study. Nowadays, the image processing and pattern recognition topics have come into prominence. The image processing concludes operation and design of systems that recognize patterns in data sets. In the past years, very difficulty in classification of microscopic images was the deficiency of enough methods to characterize. Lately, it is seen that, multi-resolution image analysis methods such as Gabor filters, discrete wavelet decompositions are superior to other classic methods for analysis of these microscopic images. In this study, the structure of the ADWEENN method composes of four stages. These are preprocessing stage, feature extraction stage, classification stage and testing stage. The Discrete Wavelet Transform (DWT) and adaptive wavelet entropy and energy is used for adaptive feature extraction in feature extraction stage to strengthen the premium features of the Artificial Neural Network (ANN) classifier in this study. Efficiency of the developed ADWEENN method was tested showing that an avarage of 97.58% recognition succes was obtained.
到目前为止,尿液细胞数量的分析和分类已成为某些疾病医学诊断的重要课题。因此,在本研究中,我们提出了一种基于自适应离散小波熵能量和神经网络分类器(ADWEENN)的新技术,用于从微观图像中识别尿液细胞,且不受旋转和缩放的影响。本研究在ADWEENN的特征提取阶段使用了一些数字图像处理方法,如降噪、对比度增强、分割和形态学处理。如今,图像处理和模式识别主题备受关注。图像处理包括识别数据集中模式的系统的操作和设计。在过去几年中,微观图像分类的一个很大困难是缺乏足够的特征表征方法。最近可以看到,诸如Gabor滤波器、离散小波分解等多分辨率图像分析方法在分析这些微观图像方面优于其他经典方法。在本研究中,ADWEENN方法的结构由四个阶段组成。这些阶段是预处理阶段、特征提取阶段、分类阶段和测试阶段。在特征提取阶段使用离散小波变换(DWT)以及自适应小波熵和能量进行自适应特征提取,以增强人工神经网络(ANN)分类器的优质特征。所开发的ADWEENN方法的效率经过测试,结果显示平均识别成功率达到了97.58%。
