Estimation and Modeling of Actual Numerical Errors in Volume Rendering
In this paper we study the comprehensive effects on volume rendered images due to numerical errors caused by the use of finite precision for data representation and processing. To estimate actual error behavior we conduct a thorough study using a volume renderer implemented with arbitrary floating-point precision. Based on the experimental data we then model the impact of floating-point pipelin...
متن کاملBathymetry and Volume Estimation of Reservoirs using OLI Imagary
Nowadays using field depth measurement to estimate capacity of water reservoirs is a costly and time consuming method. In this regard, different multiple techniques of remote sensing method has been adopted. In this study, a radiation and reflection based model was introduced to estimating the bathymetry and water capacity of reservoir by images of OLI sensor. For this, at May 17, 2015 water de...
متن کاملinvestigation of possibility of landslide number and area estimation using determination area and volume frequency distribution (case study: mazandaran providence)
landslides are the major natural hazard, causing significant damage to properties, lives and engineering projects in all mountainous areas in the world. in order to estimate the role of the landslides in erosion processes and evaluation of their risks, it is necessary to quantify landslides. this quantifying can be performed by applying the probability distributions that show the landslide size ...
متن کاملcurve estimation modeling between area and volume of landslides in tajan river basin, north of iran
determining landslide size could be a difficult and expensive task. in this research, size parameters of 142 landslides recognized in tajan river basin, northern iran, have been assessed. the dataset was prepared through the extensive field surveys and using the satellite imagery available via google earth. dependence between landslides area (a-m2), volume (v-m3), and depth (d-m) was appointed ...
متن کاملvolume estimation of potatoes using image processing
volume estimation of most agricultural products using mathematical methods is not accurate because of their irregular shape. an alternative method is image processing, which can be used in continuous sorting machines. the objective of this study is to find a practical method for volume estimation of potatoes using image processing. fifty potatoes (marfona variety) were selected as experimental ...
