Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with specific embodiments.

[0016] A plant blade identification method based on the Android platform, characterized in that, comprising the following steps:

[0017] (1) Utilize the image processing API of the Android platform to cut out the area of ​​interest in the image of the plant to be detected, and then perform step (2) if the stand-alone recognition is selected for the image of the area of ​​interest after the cropping, and step (4) if the network recognition is selected;

[0018] (2) Calculate the feature vector of the feature gradient histogram of the image of the region of interest, combine the K nearest neighbor node classifier and the support vector machine, use the database of the Android platform to classify and identify the image of the plant to be detected, and obtain the target plant to which the plant to be detected belongs type;

[0019] (3) Obtain the Euclidean distance between...

Abstract

The invention relates to a plant blade recognition method based on an Android platform. The method comprises: (1) performing tailoring of an interested area on an image of a plant to be detected, executing (2) if selecting stand-alone recognition, and executing (4) if selecting networking recognition; (2) in cooperation with a K nearest node classifier and a support vector machine, a database of the Android platform is used to perform classification recognition on the image of the plant to be detected; (3) getting the Euclidean distance of a feature description vector of the image of the plant to be detected and feature description vectors of all plant images in the database, taking the first five plant species with the smallest Euclidean distance, judging whether the obtained target plant species is among the five plant species, executing (5) if yes, and executing (4) otherwise; and (4) sending an interested image to a server side through an HTTP protocol. Compared with the prior art, the plant blade recognition method based on the Android platform processes images in real time and efficiently, and uses NDK and JNI technologies to remarkably improve the accuracy and the speed of recognition of classification.

Description

technical field [0001] The invention relates to the technical fields of digital image processing and pattern recognition, in particular to a plant leaf recognition method based on an Android platform. Background technique [0002] There are about 400,000 species of plants on the earth, and my country is the world's second largest resource bank of plant species. The classification and identification of plant species is an important basic work in botany research and agricultural production. It is the basis for human beings to understand plants, master the evolution of plants, understand the basic characteristics of plants and make use of them. It can be applied to the identification of crop diseases and insect pests and the monitoring of crop growth. At the same time, it is also closely related to fields such as agriculture, forestry, animal husbandry, sideline, fishery, and traditional Chinese medicine. Traditional plant taxonomy research generally requires manual measuremen...
