Xác định số lượng rầy nâu trưởng thành dựa trên đặc trưng sift bằng phương pháp cải tiến

Abstract

Currently, the identification of objects on rice pests can be identified by many- different methods. However, the accuracy rate is not high. Therefore, the objective is to increase the rate of identification of adult brown plant hoppers (BPH). In this research, we propose some new adjustments in the method of determining the number of plant hoppers that have been proposed [17]. Based on the proposed model, the number of BPH in different stages of rice development, such as rice tillering, booting to flowering and grain. At the same time, it is possible to distinguish between adult brown plant hoppers and others with some adjustments that are proportional to the results obtained. This result can server as a basis for improving efficiencythe density of brown plan hopper on rice growth, support for business forecasting, pest BPH on rice.
