Abstract

Diabetic detinopathy (DR) is effect of diabetes mellitus to the human vision that is the major cause of blindness. Early diagnosis of DR is an important requirement in diabetes treatment. Retinal fundus image is commonly used to observe the diabetic retinopathy symptoms. It can present retinal features such as blood vessel and also capture the pathologies which may lead to DR. Blood vessel is one of retinal features which can show the retina pathologies. It can be extracted from retinal image by image processing with following stages: pre-processing, segmentation, and post-processing. This paper contains a review of public retinal image dataset and several methods from various conducted researches. All discussed methods are applicable to each researcher cases. There is no further analysis to conclude the best method which can be used for general cases. However, we suggest morphological and multiscale method that gives the best accuracy in segmentation.

Abstract

The radiology examination by computed tomography (CT) scan is an early detection of lung cancer to minimize the mortality rate. However, the assessment and diagnosis by an expert are subjective depending on the competence and experience of a radiologist. Hence, a digital image processing of CT scan is necessary as a tool to diagnose the lung cancer. This research proposes a morphological characteristics method for detecting lung cancer lesion density by using the histogram and GLCM (Gray Level Co-occurrence Matrices). The most well-known artificial neural network (ANN) architecture that is the multilayers perceptron (MLP), is used in classifying lung cancer lesion density of heterogeneous and homogeneous. Fifty CT scan images of lungs obtained from the Department of Radiology of RSUP Dr. Sardjito Hospital, Yogyakarta are used as the database. The results show that the proposed method achieved the accuracy of 98%, sensitivity of 96%, and specificity of 96%.

Abstract

Website pemerintah adalah alat promosi yang penting untuk tujuan wisata karena merupakan saluran informasi dalam memperkenalkan semua calon wisatawan sebagai dasar keputusan perjalanan dan pemilihan destinasi. Kabupaten Bantul telah menerapkan teknik promosi melalui website. Namun sayangnya, promosi dengan menggunakan website tersebut kurang maksimal dan kurang mendapat kepercayaan pengguna, terlihat dari tingkat kunjungan pengguna ke website Disbudpar Kabupaten Bantul yang tidak selalu mengalami peningkatan per bulannya. Tujuan penelitian adalah untuk mengetahui persepsi pengguna mengenai kualitas website dan tingkat kepercayaan dalam menggunakan website sebagai media promosi pariwisata. Hal tersebut diprediksi mendorong adopsi informasi dan terwujudnya viral marketing. Peneliti mengusulkan model tingkat kepercayaaan yang memberikan pengaruh terhadap terciptanya viral marketing berdasarkan model Filieri yang dimodifikasi. Populasi melibatkan masyarakat umum yang membutuhkan informasi tentang pariwisata di Bantul yang mempunyai media sosial. Sampel dengan menggunakan metode simple random sampling. Kuesioner digunakan untuk mengumpulkan data dengan menggunakan skala Likert dan dianalisis menggunakan SEM-PLS. Hasil penelitian menunjukkan bahwa kualitas informasi dan kualitas website yang dirasakan oleh pengguna terbukti meningkatkan kepercayaan pengguna terhadap website pariwisata. Kepercayaan pengguna terhadap website pariwisata juga terbukti meningkatkan niat pengguna untuk mengadopsi informasi pariwisata dan mendorong pengguna untuk melakukan kegiatan viral marketing. Penelitian juga memberikan hasil yang menarik bahwa kualitas layanan, kepuasan pengguna serta pengalaman dan kemampuan pengguna tidak terbukti secara signifikan terhadap kepercayaan pengguna website pariwisata.

Abstract

Based on data from World Health Organization, in 2015, there are 90% of deaths caused by malaria disease in Africa, Southeast Asia and countries of eastern Mediterranean. It makes the malaria become one of the most dangerous diseases that often leads to death. To support the diagnosis of malaria, early detection of plasmodium parasite is needed. Recently, malaria diagnosis process can be done with the help of computer, or often referred to as Computer Aided Diagnosis (CAD). By utilizing the digital image from the blood staining process, digital image processing can be performed to detect the presence of malaria parasite. There are 2 types of blood smear images that can be used in the malaria diagnosis process, namely, thin blood smear images and thick blood smear images. This paper provides a review of the techniques and methods used in the diagnosis of computer-assisted malaria using thick blood smear images as a diagnostic material.

Abstract

Malarial Retinopathy (MR) is indicated by retina alteration such as white dots occurrence which is caused by malaria. Leak detection is a key factor of MR’s early diagnosis. Inconsistent size and shape of the leakages with the colour contrast that relatively similar with the background. Leak detection’s algorithm is one of the most complex algorithms on the fundus image analysis field. Therefore, improving performance in the leakage detection is essential. This study focuses on automated leakage detection on fluorescein angiography (FA) images. The methods used in this study are vessel segmentation, saliency detection, phase stretch transform (PST), optic disk removal and leak detection to extract some features which then classified to correctly validate the leak. From 20 patient data large focal leak images with 31 leak points, 28 of them have been correctly detected. So, the experiment produced the accuracy and specificity of 0.98 and 0.9, respectively. With the proposed method of this study, there is a potential to enhance the knowledge on MR field in the future.
