Skin diseases have a serious impact on people’s life and health. Current research proposes an efficient approach to identify singular type of skin diseases. It is necessary to develop automatic methods in order to increase the accuracy of diagnosis for multitype skin diseases. In this paper, three type skin diseases such as herpes, dermatitis, and psoriasis skin disease could be identified by a new recognition method. Initially, skin images were preprocessed to remove noise and irrelevant background by filtering and transformation. Then the method of grey-level co-occurrence matrix (GLCM) was introduced to segment images of skin disease. The texture and color features of different skin disease images could be obtained accurately. Finally, by using the support vector machine (SVM) classification method, three types of skin diseases were identified. The experimental results demonstrate the effectiveness and feasibility of the proposed method.

The Ideal

Many researchers have so far used machine vision and digital image processing for grabbing images of machined surfaces, improving their quality by pre-processing and then analysed them for evaluation of surface finish with a reasonable success. An attempt has been made in this work to capture the images of the surfaces with varying inclinations covering both the sides. The ideal orientation of the surface (flat and horizontal) is found by observing the variation in optical roughness parameters estimated from the grey level co-occurrence matrix as the angle of inclination changes. It is observed that the variation of roughness parameters with respect to angle of inclination also depends on the surface roughness of the component. The optical roughness values obtained by machine vision approach are then subsequently compared with the conventional Ra as obtained by stylus method and the analysis is presented.

In this paper we have studied the GLCM approach as an improvement over SWT-DCT method for feature extraction for CMFD. We have carefully studied the previously used methods and also studied the SWT-DCT method for improvement in features. We have proposed a method for the use of GLCM instead of SWT-DCT method for feature extraction which will improve the results of CMFD method used in the base work framework.

Abstrak. Pada penelitian ini akan membahas bagaimana cara mengklasifikasikan beberapa jenis rempah berdasarkan algoritma Naïve Bayes dengan menggunakan ekstraksi ciri warna RGB dan tekstur GLCM. Tahapan dalam proses klasifikasi citra digital pada penelitian ini yaitu praproses citra, segmentasi, ekstraksi ciri, klasifikasi dan uji performa Proses yang dilakukan pada penelitian ini adalah mengubah RGB to Grayscale untuk mendapatkan citra abunya, setelah mengubah citra menjadi Grayscale. Setelah melakukan image enhancement, citra di segmentasi dengan thresholding menggunakan metode Otsu. Setelah mendapatkan hasil dari segmentasi dilakukan RoI (Region of Interest) yang menghasilkan perkalian pixel. Setelah itu dilakukan ekstraksi ciri dengan menggunakan GLCM (Grey Level Co-occurrence Matrix) dan ekstraksi fitur RGB (Red, green, blue) yang di ekstrak ke dalam GLCM. Setelah mendapatkan hasil dari ekstraksi ciri maka dilakukan klasifikasi menggunakan algoritma Naïve Bayes. Tahapan terakhir pada penelitian ini adalah uji performa menggunakan K-fold cross validation dengan K=10 dan mendapatkan hasil akurasi sebesar 52%. Kata Kunci: Rempah-rempah, Naïve Bsayes, RGB, GLCM.
