A novel fuzzy clustering method based on chaos immune evolutionary algorithm (CIEFCM) is presented to solve fuzzy edge detection problems in image processing. In CIEFCM, a tiny disturbance is added to a filial generation group using a chaos variable and the disturbance amplitude is adjusted step by step, which greatly improves the colony diversity of the immune evolution algorithm (IEA). The experimental results show that the method not only can correctly detect the fuzzy edge and exiguous edge but can evidently improve the searching efficiency of fuzzy clustering algorithm based on IEA.

Three-dimensional (3D) image reconstruction technologies can reveal previously hidden microstructures in human tissue. However, the lack of ideal, non-destructive cross-sectional imaging techniques is still a problem. Despite some drawbacks, histological sectioning remains one of the most powerful methods for accurate high-resolution representation of tissue structures. Computer technologies can produce 3D representations of interesting human tissue and organs that have been serial-sectioned, dyed or stained, imaged, and segmented for 3D visualization. 3D reconstruction also has great potential in the fields of tissue engineering and 3D printing. This article outlines the most common methods for 3D tissue section reconstruction. We describe the most important academic concepts in this field, and provide critical explanations and comparisons. We also note key steps in the reconstruction procedures, and highlight recent progress in the development of new reconstruction methods.

提出了一种基于嵌入式位平面的静止连续色调图像的无损图像压缩方法:通过将1幅图像分割成两类位平面(基础层和增强层)使得该图像具有了位平面的可测量性,并且通过利用平面与平面以及每个平面中各像素之间的相关性减少冗余,从而获得优秀的压缩性能;与其他压缩算法的比较表明,基于嵌入式位平面的无损图像压缩算法由于具有位平面可测量性而体现了巨大的优越性。

At an early immature growth stage of citrus, a hyperspectral camera of 369–1042 nm was employed to acquire 30 hyperspectral images in order to detect immature green fruit within citrus trees under natural illumination conditions. First, successive projections algorithm (SPA) were implemented to select 677, 804, 563, 962, and 405 nm wavebands and to construct multispectral images from the original hyperspectral images for further processing. Then, histogram threshold segmentation using NDVI of 804 and 677 nm was implemented to remove image backgrounds. Three slope parameters, calculated from the pairs 405 and 563 nm, 563 and 677 nm, and 804 and 962 nm were used to construct a classifier to identify the potential citrus fruit. Then, a marker-controlled watershed segmentation based on wavelet transform was applied to obtain potential fruit areas. Finally, a green fruit detection model was constructed according to Grey Level Co-occurrence Matrix (GLCM) texture features of the independent areas. Three supervised classifiers, logistic regression, random forest and support vector machine (SVM) were developed using texture features. The detection accuracies were 79%, 75%, and 86% for the logistic regression, random forest, and SVM models, respectively. The developed algorithm showed a great potential for identifying immature green citrus for an early yield estimation.

在现代交通系统中,道路作为车辆和行人使用频率最高的民用基础设施之一,其服役状况和使用寿命直接影响通行体验和效率。因此,在路面发生不可逆损伤之前进行路面健康监测和及时养护,对于保障公共交通服务质量以及通行安全至关重要。通过路面结构动力响应监测和路面状况评估可有效表征路面损伤状况。埋入式传感器、图像处理和机器学习是目前常用的三种路面结构动力响应监测技术和分析方法。本文综述了近年来上述三种技术在路面工程中的应用现状,并阐述了这些技术在未来路面工程监测与分析中的发展方向。

在大型化工厂中,输送液体的管道的泄漏是一个重要的问题。管道的破损不仅会影响工厂的正常运行,同时也增加了维护成本。此外,还会使操作人员的生命安全受到威胁。因此,管道泄漏的检测与定位是维护和状态监测中的关键任务。近年来,大型工厂利用红外(IR)相机进行泄漏检测。红外相机可捕捉温度比周围环境温度高(或低)的液体泄漏。本文针对化工厂中的管道泄漏,提出了一种基于红外视频数据和机器视觉技术的检测与定位方法。由于所提出的方法是以视觉技术为基础,无需考虑泄漏液体的物理性质,因此其适用于任何类型的液体(水、油等)泄漏检测。在本方法中,首先对后续帧进行减影和分块处理,然后对每一分块进行主成分分析,提取特征;接着将分块内所有减影帧都转换为特征向量(作为块分类的依据),根据特征向量,采用k-最近邻算法将块分为正常(无泄漏)和异常(泄漏)两类;最后在各异常块上确定泄漏的位置。本文使用了两种不同格式的数据集(由红外相机拍摄的实验室工厂演示装置的视频图像组成)对上述方法进行评估。结果表明,本文提出的利用红外视频进行管道泄漏检测与定位的方法前景可观,具有较高的检测精度以及合理的检测时间。本文最后讨论了该方法在工厂进行实际推广的可能性及局限性。
