leaf classification using cnn

The developed CNN model in this paper has an excellent performance on image classification of the training set and the test set, which is consistent with the previous research. LeCun, Y., Boser, B., Denker, J. S., Henderson, D., Howard, R. E., Hubbard, W., & Jackel, L. D. (1989). The image-based plant classification has become the most important and hopeful method for botanical taxonomy (Goëau, Bonnet, & Joly, 2016). ... We used format string and regex together. Deconvolutional networks (DNs) were employed to comprehend the principle of CNN regarding plant identification. For example, the accuracy rate of the model on training sets is about 99% while the accuracy rate on test sets is merely approximately 70%. Two class labels for Tree1 and Tree2 are generated by using 2-way softmax which is fed by the output of the last fully-connected layer. The superscription l denotes the layer l, and the subscription i denotes the hidden units i in the layer l. According to Figure 5b, the values are changed as the equation (4) after the process of dropout: where ‘*’ represents the element-wise product, r^((l)) denotes a vector of independent Bernoulli random variables whose element in this vector has probability p of being 1, and y ̃^((l)) is the element-wise product of r^((l)) and y^((l)) (Srivastava et al., 2014). Therefore, plant categorisation becomes increasingly significant in the field of computer vision (Lee, Chang, Chan, & Remagnino, 2016). Since the leaves contain useful features for recognising various types of plants, so these features can be extracted and applied by automatic image recognition algorithms to classify plant species. Overfitting is a significant problem in deep learning, which refers to the deep learning model that cannot perform well on the test sets because it is over-tuned to the training sets. Also, tree leaf is an important characteristic for tree identification. Even though there are code patterns for image classification, none of them showcase how to use CNN to classify images using Keras libraries. The resolution of each image is 544 × 960. Classification of Marvel characters using CNN along with code. presented at the meeting of the 2013 IEEE International Conference on Image Processing, Melbourne, VIC, Australia. Many organisations process application forms, such as loan applications, from it's customers. Rishang Prashnani. The research question of this project is how to use CNNs to identify tree leaves. These two species of trees are labelled as Tree1 and Tree2 in this paper. The method is based on the use of the Otsu method to isolate the leaf from its background and the chlorophyll histogram to de-tect discolorations caused by the lace bug. Constructs a two-dimensional pooling layer using the max-pooling algorithm. A deep CNN can achieve record-breaking results on a very challenging dataset like imageNet by using supervised-learning methods (Krizhevsky, Sutskever, & Hinton, 2012). Also, the image should only contain the leaf for improving the accuracy rate. Myanmar is an agricultural country and then crop production is one of the major sources of earning. The accuracy rates and loss of this developed CNN model for identifying Tree1 and Tree2 are illustrated in Figure 3 and Figure 4, respectively. 3 0 obj However, the image-processing method for leaf identification of this application is not based on CNN which has been proven to be the most effective approach for 2D-image recognition. Plant study is crucial for the development of agriculture, pharmaceutics, climate study (Cope, Corney, Clark, Remagnino, & Wilkin, 2012).

This paper proposes a five-layer CNN model for leaf classification by utilising the Keras which is a high-level neural networks API. The architecture of the plant leaf image classification algorithm is based on a recent proposal by Medela et al. Three sets of features are also provided per image: a shape contiguous descriptor, an interior texture histogram, and a fine-scale margin histogram. Glorot, X., & Bengio, Y. The developed model can classify two species of tree leaves with about 100% accuracy rate on the proposed test set. A mobile application has the ability to identify plant species effectively through plant-leaf images (Kumar et al., 2012). Therefore, the image- classification algorithm of this mobile application is an area for improving image-recognition algorithms of this system. The farmer will be notified about the disease and from here, one can do a further procedure to solve the disease. More specifically, the pictures of leaves will be taken in the real environment, so that the background of the image will be the real tree instead of pure colour. 145, pp. From long time ago, people have already learned to identify different kinds of plants by examining their leaves. presented at the meeting of the CLEF 2016-Conference and Labs of the Evaluation forum, Évora, Portugal. The dataset consists approximately 1,584 images of leaf specimens (16 samples each of 99 species) which have been converted to binary black leaves against white backgrounds. Srivastava, N., Hinton, G. E., Krizhevsky, A., Sutskever, I., & Salakhutdinov, R. (2014). (2012). The developed model can classify two species of tree leaves with about 100% accuracy rate on the proposed test set. The future studies will be concentrated on three aspects.
