Abstract

Abstract Color blindness test is needed for some people who require to perform multiple tests when applying for a job or want to go to university. Test the color-blind person using tests Ishihara, Ishihara test using a sheet in which there are dots in various colors and sizes. The colored dots are arranged so as to form a circle. Because Ishihara sheet is often used, so that will cause discoloration on the sheet. Would cause color blindness test results less accurate. With the help of computers, the Ishihara sheet in manipulation using pseudocoloring. Ishihara sheet used as a digital image with RGB format and then to convert to his format, the format of this HIS hue value is shifted or replaced with other colors in accordance with the original image color contrast. After testing result, can provide a comparison between the original image with manipulation pseudocoloring Ishihara. Keywords : Ishihara, color blindness, RGB, HIS, pseudocoloring. Abstrak Tes buta warna sangat dibutuhkan bagi sebagian orang yang di haruskan untuk melakukan beberapa tes ketika melamar sebuah pekerjaan atau mau masuk Perguruan Tingggi. Menguji seseorang buta warna menggunakan tes Ishihara, tes Ishihara menggunakan lembaran yang didalamnya terdapat titik-titik dengan berbagai warna dan ukuran. Titik berwarna tersebut disusun sehingga membentuk lingkaran. Karena lembaran Ishihara ini sering digunakan, sehingga akan menyebabkan perubahan warna pada lembaran tersebut. Akan menyebabkan hasil tes buta warna kurang akurat. Dengan bantuan komputer, lembaran Ishihara tersebut di manipulasi menggunakan pseudocoloring. Lembaran Ishihara dijadikan citra digital dengan format RGB, kemudian di-konversikan ke format HIS, pada format HIS ini nilai hue digeser atau diganti dengan warna lain sesuai dengan kontras warna citra asli. Setelah dilakukan uji coba diperoleh hasil, dapat memberikan perbandingan antara citra asli Ishihara dengan manipulasi pseudocoloring. Kata kunci : Ishihara, buta warna, RGB, HIS, pseudocoloring.

Abstract

In general, monitoring of animal growth and health is done directly by farmers (invasive measurement methods) which can cause cows to be injured or experience stress. To avoid this, several studies have been conducted on non-invasive methods using image processing technology. In this study, we systematically reviewed several works of literature to identify and synthesize published articles on image processing technology and image processing applications related to weight estimation and individual cattle identification. Analysis of image processing technologies used for weight estimation and individual cattle identification is the main objective of this article. Articles were searched through several databases and studies that met the inclusion criteria were analyzed and used in the review. The studies were divided into three main themes: image processing technologies, applications using image processing, and image processing research on cattle growth and health. It can be concluded that deep learning approaches are increasingly being studied, tested and considered as a viable and promising approach to monitor cattle weight and health in several aspects

Abstract

Penelitian ini bertujuan untuk mengembangkan sistem pendeteksian benda terhalang yang efektif dan efisien menggunakan metode diagram Venn. Sistem ini dirancang untuk membedakan objek yang terhalang dan terdistorsi, yang sulit dideteksi oleh komputer. Metode diagram Venn membagi situasi pendeteksian menjadi empat kategori berdasarkan kondisi objek acuan, warna dominan, dan posisi dominan. Sistem menghasilkan pertanyaan yang efektif dan efisien berdasarkan kategori tersebut, menghasilkan rata-rata 2 hingga 3 pertanyaan untuk mendeteksi objek, dibandingkan dengan 4 hingga 5 pertanyaan yang dibutuhkan manusia. Hasil penelitian menunjukkan bahwa sistem pendeteksian benda terhalang dengan diagram Venn lebih efektif dan efisien dibandingkan dengan metode manual. Sistem ini dapat membantu meningkatkan akurasi dan kecepatan deteksi objek dalam berbagai aplikasi, seperti pengenalan gambar, robotika, dan augmented reality.

Abstract

Semi-active dampers reduce the effects of shock vibrations because they can operate at specific vibration frequencies at a lower cost than more complex active dampers.  PSMEID is one of the alternative methods developed in the semi-active damping system. PSMEID has been developed by adapting it by adding a PSMEID active time prediction system when an impact occurs. This research attempts to compare two types of PSMEID with active time prediction, where the position of each model offered has a different PSMEID mass position when applied to the landing gear damper of an Unmanned Aerial Vehicle (UAV). This comparison aims to give the user a choice among these optimal models suitable for use in multiple conditions. When simulated using the same parameter values, the PSMEID placed on the unsprung mass can reduce acceleration amplitude by up to 6.6 percent when the landing gear is dropped at 0.15 meters from the ground. The model that places the PSMEID on the sprung mass can help reduce the velocity amplitude up to 8.8 percent when dropped at a height of 0.05 meters, and the spring constant value of the PSMEID (KPS) is 1600 N/m. All these simulations show that the PSMEID should be activated just before the landing gear hits the runway surface (TB < TL).
