فضای سبز شهری در مناطق گوناگون جهان جزء ضروریات روزمره و جذابیت های محلی است. انتخاب گونه های مقاوم به خشکی برای کاشت در فضای سبز شهری در مناطق خشک و نیمه خشک به منظور ایجاد تنوع امری ضروری است. یکی از آزمایش های مهم سازگاری، به منظور معرفی گیاهان در مناطق جدید، بررسی ظهورشناسی گونه هاست. هدف اصلی این تحقیق شناسایی خصیصه های ظهورشناسی گونۀ بلوط به دو روش توصیفی و با استفاده از سری زمانی عکس برد...

The biophysical properties of a crop are good indicator potential stress conditions. However, these visible cannot indicate areas exhibiting non-visible stress, e.g., early water or nutrient stress. In this research, maize including canopy height and Leaf Area Index (LAI), estimated using drone-based RGB images, were used to identify stressed in the farm. First, APSIM process-based model was si...

The consolidation of unmanned aerial vehicle (UAV) photogrammetric techniques for campaigns with high and medium observation scales has triggered the development new application areas. Most these vehicles are equipped common visible-band sensors capable mapping areas interest at various spatial resolutions. It is often necessary to identify vegetated masking purposes during postprocessing phase...

Sedimentation in reservoirs is a prerequisite for sustainable water management. The Dez dam is very important the country because of its role in electricity frequency adjustment. The main objective of this research is to identify the sources of sediment in the catchment using satellite images, GIS and hydro-geological information. For this purpose, the lab results of sediments mineralogy reveal...

Space situational awareness (SSA) system requires recognition of space objects that are varied in sizes, shapes, and types. The images challenging because several factors such as illumination noise thus make the task complex. Image fusion is an important area image processing for various applications including RGB-D sensor fusion, remote sensing, medical diagnostics, infrared visible fusion. Re...

We present BV photometry of the Sculptor dwarf galaxy to V = 22. These data give evidence for a bimodality in Sculptor’s metallicity distribution based on a discontinuity in the luminosities of horizontal branch (HB) stars and by the presence of two distinct red giant branch (RGB) bumps. A consistent picture of the evolved stars in Sculptor is given by the presence of (1) a metal-poor populatio...

In this paper we propose a multispectral image compression based on lossy to lossless coding, suitable for both spectral and color reproduction. The proposed method divides a multispectral image data into two groups, RGB and residual. The RGB component is extracted from the multispectral image, for example, by using the XYZ Color Matching Functions, a color conversion matrix, and a gamma curve....

This paper studies the problem of RGB-D object recognition. Inspired by the great success of deep convolutional neural networks (DCNN) in AI, researchers have tried to apply it to improve the performance of RGB-D object recognition. However, DCNN always requires a large-scale annotated dataset to supervise its training. Manually labeling such a large RGB-D dataset is expensive and time consumin...
