In present days remote sensing is most used application in many sectors. This remote sensing uses different images like multispectral, hyper spectral or ultra spectral. The remote sensing image classification is one of the significant method to classify image. In this state we classify the maximum likelihood classification with fuzzy logic. In this we experimenting fuzzy logic like spatial, spe...
In this paper a new fuzzy method for 2D texture classification is proposed. A fuzzy rule base system is designed based on computed Geometric Moments (GMs), which are rotation, scale and translation invariant, for each texture class. Although GMs are applied to classify texture, utilizing fuzzy inference system (FIS) to make decision, develops much more robust classifier. Where GMs are inputs an...
: ناحیه فضای رونویسی داخلی(its) به طور گسترده در سطوح مختلف تاکسونومیکی در مطالعات فیلوژنی استفاده می شود. سه گونه از جنس ribes در جنگل های ارسباران شناخته شده است. روابط فیلوژنی بین این سه گونه r. biebersteinii، r. oriental،r. uva-crispa روشن نشده است. در این مطالعه، روابط فیلوژنی مبتنی بر صفات موفولوژیکی (رنگ میوه،کرکدار بودن برگ،خار در شاخه و ....) و توالی نوکلئوتیدی nrdna its ، این گونه ها ...
This paper presents classification of various land cover types from the raw satellite image using supervised classifiers and performances of the classifiers are analyzed. Geo coded and Geo-referenced remote sensed images from Survey of India, Government of India Topographical maps are used. Prior to classification, Training process to assemble a set of statistics describing spectral response pa...
Text Classification is an important research field in information retrieval and text mining. The main task in text classification is to assign text documents in predefined categories based on documents’ contents and labeled-training samples. Since word detection is a difficult and time consuming task in Persian language, Bayesian text classifier is an appropriate approach to deal with different...
Maximum likelihood and neural classifiers are two typical techniques in image classification. This paper investigates how to adapt these approaches to hyperspectral imaging for the classification of five kinds of Chinese tea samples, using visible light hyperspectral spectroscopy rather than near-infrared. After removal of unnecessary parts from each imaged tea sample using a morphological crop...
