سنجنده‌های دوقلوی MSI سنتینل‌-2، از لحاظ توان تفکیک مکانی، شباهت بسیاری به سنجندة OLI لندست 8 دارند که آژانس فضایی اروپا، با هدف افزایش داده‌های ادامه‌دار برای پایش سطح زمین، آنها را فضا پرتاب کرد. در این مطالعه، قابلیت داده‌ها واحدهای سنگی و دگرسانی، محدودة کانسار فسفات اسفوردی، ارزیابی تلفیق‌شده، مقایسه شد. بارزکردن منطقه، روش بسط عدم همبستگی استفاده به‌منظور مقایسه‌های آماری، اجرای ماشین برد...

The notion of missing at random (MAR) plays a central role in the theory underlying current methods for handling missing data. However the standard definition of MAR is difficult to interpret in practice. In this paper, we assume the missing data model is represented as a directed acyclic graph that not only encodes the dependencies among the variables but also explicitly portrays the causal me...

In the present paper, the theoretical background of multivariate autoregressive modelling (MAR) is explained. The motivation for MAR modelling is the need to study the linear relationships between signals. In biomedical engineering, MAR modelling is used especially in the analysis of cardiovascular dynamics and electroencephalographic signals, because it allows determination of physiologically ...

In this paper, we propose an adaptive predictive coding method based on image segmentation for lossless compression. MAR (Multiplicative Autoregressive) predictive coding is an efficient lossless compression scheme. Predictors of the MAR model can be adapted to changes in the local image statistics due to its local image processing. However, the performance of the MAR method is reduced when app...
