Development of e-nose herb recognition system based on artificial intelligence techniques

Herbs are useful for various applications especially in nutraceutical products and botanical medicine. In normal practice, the herbs identification is done mainly by botanists. However, it is difficult for botanists to recognize herbs based on aroma for the species under the same family. Thereupon,...
