چکیده

Three depth recovery methods are presented. The methods are based on focusing, zooming, and motion stereo, using a single camera. An introduction to the individual methods is given, followed by an analysis of the error functions. The analysis is used to determine whether the methods are applicable for integration into a single system, enabling recovery of exible and robust depth estimates. Experimental results are presented. The focus and zoom technique have been found to be of little use, due to restrictions within the methods. The motion stereo technique can be used as a single mean to obtain depth information , even in natural images. Using this method combined with conventional stereo will enable robust and exible depth recovery .

Effect of tillage and planting methods on soil physical properties, grain yield and milling recovery of rice (Oryza sativa L. cv. Hashemi)

To evaluate the effects of tillage and planting systems on soil physical properties, grain yied and its components, and milling recovery of rice (cv. Hashemi), an experiment was conducted at Rice Research Institute of Iran in 2017 and 2018 cropping seasons-using split plot arrangements in randomized complete block design with three replications. The experimental factors were; tillage methods (m...

An Investigation of Oil Spreading Coefficient in Carbonated Water+ Gas + Oil System: an Experimental Study in an Iranian Asphaltenic Oil Reservoir

To provide supplementary oil recovery after the primary and secondary processes, enhanced oil recovery (EOR) techniques are introduced. Carbonated water injection (CWI) as an EOR method can improve sweep efficiency and the risk of gas leakage. On the other hand, the interfacial tension (IFT) is one of the key factors which can affect fluid displacement during the process of CWI greatly. Therefo...

Spatial analysis of rural groundwater resources in order to identify critical zones (Case study: Mahidasht watershed in Kermanshah province, Iran)

Introduction According to the theoretical frameworks in the spatial analysis, every "structure" in space has a specific "function". To study phenomena and to identify the relationships between them, these two concepts are of particular importance, especially in the "structural-functional dynamism" approach. The basic premise of this approach is based on the existence of a link between the stru...

Microclimate Conditions and Space Use Variations

This paper is a part of study about the impact of the microclimate on the space use and the user’s behaviours. The purpose of our study is to get an in-depth understanding of how people use out door public spaces in different climatic conditions, how their behaviour and perception of the space change with the climatic variations. We have employed a multi-method approach which combines a “qualit...
