Overall model performance and determinants of estimation accuracy
نویسندگان
چکیده
At the level of the data input (i), the resolution that the FAPs provide for a given set of potential prey species (i.e., separation of distributions in FAP space), as well as their co-linearity in FAP space will be major determinants of accuracy. Furthermore, the accuracy of conversion coefficients will bear strongly on the model’s ability to estimate correct diet proportions (Iverson et al., 2004). In the following, we will illustrate the respective effect of each of these factors using simulations.

The effect of topography on the radiance record in satellite image, probably reduce the accuracy of algorithem impliementation on the images . Therefore, to reduce the effect of topography, various correction models based on interaction between light and object needs to be defined. This research introduces lombertin correction model (Cosine model) and non_lombertin correction model (mineart and...
متن کاملPerformance evaluation of EPM and MPSIAC Models for determination of Erosion Status of Shahriari Watershed
Soil erosion is one of the most important environmental issues in developing countries, including Iran that there is inaccurate information about its amount and distribution. For this purpose, the accuracy and distribution of erosion classes obtained from EPM and MPSIAC models as compared to BLM as ground truth values were evaluated in Shahriari watershed. First, the required data and informati...

Rainfall-runoff models are used in the field of hydrology and runoff estimation for many years, but despite existing numerous models, the regular release of new models shows that there is still not a model that can provide sophisticated estimations with high accuracy and performance. In order to achieve the best results, modeling and identification of factors affecting the output of the model i...
متن کاملCamera Arrangement in Visual 3D Systems using Iso-disparity Model to Enhance Depth Estimation Accuracy
In this paper we address the problem of automatic arrangement of cameras in a 3D system to enhance the performance of depth acquisition procedure. Lacking ground truth or a priori information, a measure of uncertainty is required to assess the quality of reconstruction. The mathematical model of iso-disparity surfaces provides an efficient way to estimate the depth estimation uncertainty which ...
