The paper describes a new method to segment ischemic stroke region on computed tomography (CT) images by utilizing joint features from mean, standard deviation, histogram, and gray level co-occurrence matrix methods. Presented unsupervised segmentation technique shows ability to segment ischemic stroke region.

Recently, texture-based features have been used for digitized historical document image segmentation. It has been proven that these methods work effectively with no a priori knowledge. Moreover, it has been shown that they are robust when they are applied on degraded documents under different noise levels and kinds. In this paper an approach of evaluating CIFED 2014, pp. 41–56, Nancy, 18-21 mar...

Recently, there has been an increase in the number of hazardous events, such as fire accidents. Monitoring systems that rely on human resources depend on people; hence, the performance of the system can be degraded when human operators are fatigued or tensed. It is easy to use fire alarm boxes; however, these are frequently activated by external factors such as temperature and humidity. We prop...

Normally, the artifacts are found in a fractured state and mixed randomly and the process of manual classification may requires a great deal of time and tedious work. Therefore, classifying these fragments is a challenging task, especially if the archaeological object consists of thousands of fragments. Hence, it is important to come up with a solution for the classification of the archaeologic...

The purpose of this work was to apply and test Haralick’s gray level co-occurrence matrix (GLCM) technique for automatic calculation and segmentation of the ischemic stroke volume from CT images. For this task, the 3nearest neighbors classifier was trained to perform stroke and non-stroke area classification. The segmentation and classification results were compared versus a manual segmentation...

A n-dimensional classification problem may be visualized in (n+1) dimensions using the class label as the (n + 1)th dimension. In such visualization, the class label provides a surface which is smooth in regions where classes are non-interlaced and rough in regions where classes are interlaced. The texture of the “class label surface” thus provides an intuitive measure of pattern classifiabilit...

background: lung cancer is one of the fatal cancers in iran while 12% of the mortalities are related to this cancer in the country. this active hospital-based study was undertaken to determine the occurrence of lung cancer in fars province, southern iran. methods: data including face-to-face interview with patients and a survey of their medical and demographic records in relation to all invasiv...

teratomas are emberyonal neoplasms derived from totipotential cells that contain tissue from at least two and more often three germ layers (ectoderm, enoderm and mesoderm) in the midline or paraxial location from brain to sacrococcygeal region. the primary objective of this study is to determine this rather common newborn and children teratomas in different areas of the body. the secondary obje...

Shale oil resources are important supplements for the gradually decreasing production from conventional reservoirs. Although exploitation and development of shale have achieved considerable progress in last decade, commercial extraction hydrocarbons shales is still difficult, especially lacustrine sedimentary basins China. One key points controlling successful systems understanding occurrence m...
