| Abstract: | Chlorophyll content and distribution in plant's leaves is an important index in estimation of plant nutrition information.In the present work,chlorophyll content and distribution in tea plant's leaves were measured by hyperspectral imaging technique.First,hyperspectral image data were captured from tea plant's leaves;then seven kinds of algorithms were used to extract the characteristic parameters from hyperspectral image;finally,seven fitted models were developed using the characteristics vectors and the r... |
