Conclusion

Agriculture plays a significant role in improving the economic condition of any country. The crop growth is reduced due to weeds. Earlier the weeds were detected manually, however it is a very expensive and time consuming process. Currently, weed detection is done by robotics, automatic sprayer and weed cutting are thus used. This kind of robotics… Continue reading Conclusion

Neural network classifier

The image data are trained through the convolution neural network. The input is given as the feature-​based image which separates the weed and plants in the segmented image. The convolution operation is performed on the matrix of pixels and trained through extracted features. The two layers involved are fully connected and pooling layers. The pooling layer… Continue reading Neural network classifier

Support vector machine classifier

The machine learning algorithm of SVM is supervised method and used for both regression and classification problems. In SVM algorithm, given plot of image data with n number of features each feature belongs to a particular dimension. Here the two classes are distinguished as weed and as plant. The SVM is a linear hyper plane… Continue reading Support vector machine classifier

Feature extraction

The structure represents texture-​based local properties of micro-​texture and macro textures represent the spatial texture of narrow properties. These properties are not similar between the image pixels. The statistical features based method builds relationship among the gray levels. One-​pixel based classifiers known as first order derivative and more than two pixels based classifier is known… Continue reading Feature extraction

Proposed interval type II intuitionistic fuzzy c means with spatial triangular fuzzy number

This algorithm decreases various uncertainties in histopathology images. It comprises the following steps: This proposed algorithm detects the weed from various crop images by selecting GLCM features from segmented image. Segmentation of the weed from crops and soil in the input image properly. These results are shown in Figure 3.3. The weed and crops in same… Continue reading Proposed interval type II intuitionistic fuzzy c means with spatial triangular fuzzy number

Image segmentation

Advanced fuzzy set theory is mostly used in real-​time applications such as medical, satellite and agricultural field (Rani and Amsini 2019). In 1975, Zadeh pioneered another advanced fuzzy set called type II fuzzy set. Obviously, membership functions were defined by an expert based on his or her knowledge. These fuzzy set theories were applied to… Continue reading Image segmentation

Image preprocessing

An image Z with M rows and N columns and its intensity level range is measured as a collection of fuzzy singletons. The intensity range is in between L, 0 to 1. The membership value μik with color intensity xn xm is considered. The contrast intensification operator was introduced by Zadeh in 1973. This operator is fully dependent… Continue reading Image preprocessing

Literature survey

An exhaustive research was done on several papers describing various methods adopted for weed detection. These papers were summarized as follows. Image processing techniques and machine vision are broadly used in various fields such as agriculture industry or for detection of an object. The images are mathematically represented as rows and columns with red. So,… Continue reading Literature survey
