Penelitian ini bertujuan untuk mengetahui tingkat akurasi model dengan variasi dataset yang kami berikan dan mendefinisikan masing-masing label objek non-shadow dan shadow merupakan metode yang digunakan untuk membedakan antara bayangan dan objeknya yang mirip. Pelatihan model dilakukan dengan fine-tuning Faster R-CNN pada kerangka kerja Pytorch menggunakan arsitektur ResNet50 sebagai rancangan dasar. Implementasi model untuk dapat mendeteksi bayangan diterapkan pada video perjalanan kendaraan otonom. Hasil penelitian menunjukkan bahwa dari kelima model yang dibuat, model P5 berhasil mendeteksi bayangan dengan rata-rata akurasi F1-score sebesar 46%. Kata-kata kunci: Bayangan, Deteksi, Faster R-CNN, R-CNN, ResNet50, Pytorch Abstract Shadow objects exhibit varying intensities and shapes, which can pose problems in autonomous vehicle vision systems. Shadows generated by trees, buildings, and other objects in the vicinity of the road can impact the performance of the recognition and tracking system. Thus, a shadow detection model is necessary to determine the location of shadows, which can be employed in studies related to shadow removal. This study aims to determine the accuracy level of the model with our given diverse dataset and defining distinct labels for non-shadow and shadow objects to differentiate between shadows and similar-looking objects. The model training was performed by fine-tuning Faster R-CNN on the PyTorch framework, utilizing ResNet50 as the backbone architecture. The implemented model aimed to detect shadows in videos of autonomous vehicle. The results indicated that out of the five models developed, P5 model successfully detected shadows with an average accuracy based on F1-score is 0.46%.

Abstract

Liver cirrhosis and nephrolithiasis are significant health problems with different pathophysiological mechanisms. Liver cirrhosis, the final stage of chronic liver disease, is characterized by fibrosis and regenerative nodules, leading to severe complications, including portal hypertension and liver failure. Nephrolithiasis, commonly known as kidney stones, is a common urological condition characterized by the formation of stones in the renal system. Although these conditions are distinct, metabolic and physiological changes in cirrhotic patients may predispose to nephrolithiasis. It was reported that a man came to the emergency room of RSUD Dr. Suhatman MARS with complaints of left-sided low back pain that had been felt for 1 week. The complaint was accompanied by shortness of breath which was getting worse over time. The patient also felt cough, headache, nausea, fatigue, urine slightly coloured like tea, weight loss. The patient has a history of untreated kidney stones. The patient has a history of hepatitis 31 years ago. The main objective of investigating the coexistence of liver cirrhosis and nephrolithiasis is to understand the relationship between these two conditions and to develop effective management strategies that can address their combined impact on patients.

Abstract

Identifikasi kayu salah satu kebutuhan untuk mendukung pemerintah dan kalangan bisnis kayu untuk melakukan perdagangan kayu secara legal. Keahlian khusus dan waktu yang cukup dibutuhkan untuk memproses identifikasi kayu di laboratorium. Beberapa metodologi penelitian sebelumnya, proses identifikasi kayu masih dengan cara menggabungkan sistem manual menggunakan anatomi DNA kayu. Sedangkan penggunaan sistem komputer diperoleh dari citra penampamg melintang kayu secara proses mikrokopis dan makroskopis. Saat ini, telah berkembang teknologi computer vision dan machine learning untuk mengidentifikasi berbagai jenis objek, salah satunya citra kayu. Penelitian ini berkontribusi dalam mengklasifikasi beberapa spesies kayu yang diperdagangkan menggunakan Deep Convolutional Neural Networks (DCNN). Kebaruan penelitian ini terletak pada arsitektur DCNN yang bernama Kayu7Net. Arsitektur Kayu7Net yang diusulkan memiliki tiga lapisan konvolusi terhadap tujuh spesies dataset citra kayu. Pengujian dengan merubah citra input menjadi berukuran 600×600, 300×300, dan 128×128 piksel serta masing-masing diulang pada epoch 50 dan 100. DCNN yang diusulkan menggunakan fungsi aktivasi ReLU dengan batch size 32. ReLU bersifat lebih konvergen dan cepat saat proses iterasi. Sedangkan Fully-Connected (FC) berjumlah 4 lapisan akan menghasilkan proses training yang lebih efisien. Hasil eksperimen memperlihatkan bahwa Kayu7Net yang diusulkan memiliki nilai akurasi sebesar 95,54%, precision sebesar 95,99%, recall sebesar 95,54%, specificity sebesar 99,26% dan terakhir, nilai F-measure sebesar 95,46%. Hasil ini menunjukkan bahwa arsitektur Kayu7Net lebih unggul sebesar 1,49% pada akurasi, 2,49% pada precision, dan 5,26% pada specificity dibandingkan penelitian sebelumnya. AbstractWood identification is one of the needs to support the government and the wood business community for a legally wood trading system. Special expertise and sufficient time are needed to process wood identification in the laboratory. Some previous research works show that the process of identifying wood combines a manual system using a wood DNA anatomy. While, the use of a computer system is obtained from the wood image of microscopic and macroscopic process. Recently, the latest technology has developed by using the machine learning and computer vision to identify many objects, the one of them is wood image. This research contributes to classify several the traded wood species by using Deep Convolutional Neural Networks (DCNN). The novelty of this research is in the DCNN architecture, namely Kayu7Net. The proposed of Kayu7Net Architecture has three convolution layers of the seven species wood image dataset. The testing changes the wood image input to 600×600, 300×300, and 128×128 pixel, respectively, and each of them repeated until 50 and 100 epoches, respectively. The proposed DCNN uses the ReLU activation function and batch size 32. The ReLU is more convergent and faster during the iteration process. Whereas, the 4 layers of Fully-Connected (FC) will produce a more efficient training process. The experimental results show that the proposed Kayu7Net has an accuracy value of 95.54%, a precision of 95.99%, a recall of 95.54%, a specificity of 99.26% and finally, an F-measure value of 95.46%. These results indicate that Kayu7Net is superior by 1.49% of accuracy, 2.49% of precision, and 5.26% of specificity compared to the previous work.
