Rapeseed pests will result in a rapeseed production reduction. The accurate identification of rapeseed pests is the foundation for the optimal opportunity for treatment and the use of pesticide pertinently. Manual recognition is labour-intensive and strong subjective. This paper propsed a image recognition method of rapeseed pests based on the color characteristics. The GrabCut algorithm is adopted to segment the foreground from the image of the pets. The noise with small area is filtered out. The benchmark images is obtained from the minimum enclosing rectangle of the rapeseed pests. Two types of color feature description of pests is adopt, one is the three order color moments of the normalized H/S channel; the other is the cross matching index calculated by the reverse projection of the color histogram. A multi-dimensional vector, which is used to train the random forest classifier, is extracted from the color feature of the benchmark image. The recognition results can be obtained by inputing the color features of the image to be detected to the random forest classifier and training.The experiment showed that the proposed method may identify five kinds of rapeseed accurately such as erythema, cabbage caterpillar, colaphellus bowringii baly, flea beetle and aphid with the recognition rate of 96%.

Abstrak - Proses identifikasi atau pengenalan biji-bijian merupakan aspek penting dalam dunia industri pengolahan pangan. Sebuah industri pangan berskala besar, proses pencampuran beberapa macam biji-bijian dalam pengolahan sebuah produk pangan sangat memperhatikan ketepatan dalam memilih bahan agar tidak terjadi kesalahan dalam proses produksi karena berpengaruh pada hasil akhir dari sebuah produksi. Agar tidak terjadi kesalahan yang fatal, diperlukan sebuah proses identifikasi dari bahan yang digunakan. Dengan sebuah sensor (intelligent camera) yang digunakan dari hasil sebuah proses identifikasi maka sebuah proses produksi produk pangan dapat berjalan dengan baik dan tidak terjadi kesalahan dalam pencampuran bahan. Proses pengidentifikasian terhadap beberapa varian biji-bijian dapat dilakukan dengan cara mengekstraksi fitur dari citra (image) dengan menganalisa melalui parameter warna, bentuk dan tekstur serta melakukan proses pengklasifikasian untuk mengukur tingkat keakuratan.  Penelitian ini melakukan identifikasi terhadap varian biji-bijian (padi, jagung, kacang tanah dan kedelai) dengan melakukan ekstraksi fitur warna menggunakan RGB dan HSV, ekstraksi fitur bentuk menggunakan Morphological Threshold dan ekstraksi fitur tekstur menggunakan Grey Level Co-occurrence Matrix (GLCM) dan Local Binary Pattern (LBP). Untuk proses pengklasifikasian, peneliti menggunakan metode Random Forest Classifier (RF) untuk mendapatkan tingkat akurasi yang tinggi dengan batasan-batasan yang mempengaruhi keakuratan dalam proses pengklasifikasian untuk dikembangkan dalam proses selanjutnya. Peneliti menggunakan tools MATLAB R2015b untuk proses identifikasi mulai dari proses ekstraksi fitur sampai proses klasifikasnya. Berdasarkan hasil pengujian yang dilakukan didapatkan tingkat akurasi sebesar 99.8 %. Dapat disimpulkan bahwa pengambilan dataset berupa gambar atau image biji-bijian yang diteliti dapat dijadikan patokan untuk pengidentifikasian dan dapat dikembangkan dalam proses selanjutnya.

The importance of automatic pollen recognition has been examined in several areas ranging from paleoclimate studies to some daily practice such as pollen hypersensitivity forecasting. This paper attempts to present an automatic 3D pollen image recognition method based on convolutional neural network. To achieve this purpose, high feature dimensions and complex posture transformation should be taken into account. Therefore, this work focuses on a three-part novel approach: constructing spatial local key points to obtain local stable points of pollen images, computing orientational local binary pattern using local stable points as the inputs, and identifying the pollen grains using convolutional neural network as the classifier. Experiments are performed on two standard pollen image datasets: Confocal-E dataset and Pollenmonitor dataset. It is concluded that the proposed approach can effectively extract the features of pollen images and is robust to posture transformation, slight occlusion, and pollution.

AbstractWe sought to evaluate the utility of radiomics for Amide Proton Transfer weighted (APTw) imaging by assessing its value in differentiating brain metastases from high- and low grade glial brain tumors. We retrospectively identified 48 treatment-naïve patients (10 WHO grade 2, 1 WHO grade 3, 10 WHO grade 4 primary glial brain tumors and 27 metastases) with either primary glial brain tumors or metastases who had undergone APTw MR imaging. After image analysis with radiomics feature extraction and post-processing, machine learning algorithms (multilayer perceptron machine learning algorithm; random forest classifier) with stratified tenfold cross validation were trained on features and were used to differentiate the brain neoplasms. The multilayer perceptron achieved an AUC of 0.836 (receiver operating characteristic curve) in differentiating primary glial brain tumors from metastases. The random forest classifier achieved an AUC of 0.868 in differentiating WHO grade 4 from WHO grade 2/3 primary glial brain tumors. For the differentiation of WHO grade 4 tumors from grade 2/3 tumors and metastases an average AUC of 0.797 was achieved. Our results indicate that the use of radiomics for APTw imaging is feasible and the differentiation of primary glial brain tumors from metastases is achievable with a high degree of accuracy.
