متن کاملSupervised color constancy using a color chart
One of the key problems in machine vision is color constancy: the ability to match object colors in images taken under different colors of illumination. This is a difficult problem because the apparent color will depend upon the spectral reflectance function of the object and the spectral distribution function of the incident light, both of which are generally unknown. Methods to solve this pro...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولTiming and Rate of Phosphorus Application Influence Maize Phenology, Yield and Profitability in Northwest Pakistan
Phosphorus (P) is the second most important crop nutrient after nitrogen that increases productivity and profitability of maize (Zea mays L.) on P deficient soils in Northwest Pakistan. The objective of this study was to find the best level and time of P application for higher maize (cv. Azam) productivity and profitability. Field experiment was conducted at the Research Farm of Khyber Pakhtunk...
متن کاملexperiments on variable-mass threshing of rice in the tangential-longitudinal-flow combine harvester
the existing studies of threshing process of combine harvesters adopt the assumption of constant mass, which is contradictory to the phenomenon of separation of grains and short stalks in actual threshing process. therefore, the characteristics of threshing and separation are not accurately described. aiming at this problem, this study established the tangential-longitudinal threshing and separ...
