Automated and accurate classification of brain MRI is such important that leads us to present a new robust classification technique for analyzing magnetic response images. The proposed method consists of three stages, namely, feature extraction, dimensionality reduction, and classification. We use gray level co-occurrence matrix (GLCM) to extract features from brain MRI and for selecting the be...
اکثر الگوریتم های طبقه بندی داده های سنجش از دور بر اساس ویژگی ها و اطلاعات طیفی پیکسل ها عمل می کنند. این مسئله باعث نادیده گرفتن اطلاعات مکانی مفید قابل استخراج از این تصاویر، مانند؛ بافت تصاویر می شود. استفاده هم زمان از بافت و اطلاعات طیفی مبحثی است که به آن کمتر پرداخته شده است. در این پژوهش تاثیر استفاده از بافت تصویر تک باند سنجنده ali بر دقت طبقه بندی تصاویر ابرطیفی سنجنده هایپریون در...
In modern textile industry, Tissue online Automatic Inspection (TAI) is becoming an attractive alternative to Human Vision Inspection (HVI). HVI needs a high level of attention nevertheless leading to low performance in terms of tissue inspection. Based on the co-occurrence matrix and its statistical features, as an approach for defects textile identification in the digital image, TAI can poten...
INTRODUCTION The goals of this study were (i) to compare the prevalence of focal knee abnormalities, the mean cartilage T2 relaxation time, and the spatial distribution of cartilage magnetic resonance (MR) T2 relaxation times between subjects with and without risk factors for Osteoarthritis (OA), (ii) to determine the relationship between MR cartilage T2 parameters, age and cartilage morphology...
Traditional spectral classification of remote sensing data applied on per pixel basis ignores the potentially useful spatial information between the values of proximate pixels. Although spatial information extraction has been greatly explored, there have been limited attempts to enhance classification by combining spectral and spatial information. This improvement would arise from the hypothesi...
