Comparision of some models for estimation of reflectance of hypericum leaves under stress conditions
Temizel, Kadir Ersin; Odabas, Mehmet Serhat; Senyer, Nurettin; Kayhan, Gokhan; Bajwa, Sreekala Gopalapillai; Caliskan, Omer; Ergun, Erhan (De Gruyter Open Ltd, 2014)Lack of water resources and high water salinity levels are among the most important growth-restricting factors for plants species of the world. This research investigates the effect of irrigation levels and salinity on ... -
Determination of Reflectance Values of Hypericum'S Leaves Under Stress Conditions Using Adaptive Network Based Fuzzy Inference System
Odabas, Mehmet Serhat; Temizel, Kadir Ersin; Caliskan, Omer; Senyer, Nurettin; Kayhan, Gokhan; Ergun, Erhan (Acad Sciences Czech Republic, Inst Computer Science, 2014)The effects of water stress and salt levels on hypericum's leaves were examined on greenhouse-grown plants of Hypericum perforatum L. by spectral reflectance. Salt levels and irrigation levels were applied 0, 1, 2.5 and 4 ... -
The Estimation of Adult and Nymph Stages of Aphis Fabae (Hemiptera: Aphididae) Using Artificial Neural Network
Saruhan, Islam; Senyer, Nurettin; Ayvaz, Tamer; Kayhan, Gokhan; Ergun, Erhan; Odabas, Mehmet Serhat; Akca, Izzet (Amer Entomol Soc, 2015)In this research, the estimation of adult and nymph stages and adult of Aphis fabae was investigated using artificial neural network. Determining A. fabae nymph stages is difficult. Morphometric study of different parts ... -
Estimation of Chlorophyll Concentration Index at Leaves using Artificial Neural Networks
Odabas, Mehmet Serhat; Senyer, Nurettin; Kayhan, Gokhan; Ergun, Erhan (World Scientific Publ Co Pte Ltd, 2017)In this study, the effectiveness of an SPAD-502 portable chlorophyll (Chl) meter was evaluated for estimating the Chl contents in leaves of some medicinal and aromatic plants. To predict the individual chlorophyll concentration ... -
Symmetrical Triangular Switching Fuzzy Filter with Four Directional Average Value Center for the Removal of Salt and Pepper Noise
Altinisik, Pelin; Ergun, Erhan (Ieee, 2015)In this study, a filter is proposed in order to remove the salt and pepper noise in images. This filter is named as symmetrical triangular switching fuzzy filter with four directional average value center (TSFDAV). TSFDAV ... -
