Abstract:
Smart-Kameras sind ein elementarer Bestandteil in der industriellen Fertigung. Jedoch veraltet deren Datenverarbeitungshardware schnell, während die Optik langlebig ist. Um Bildanalysealgorithmen mit erhöhtem Ressourcenbedarf trotz Limitierung der Smart-Kamera in Fertigungsanlagen flexibel integrieren zu können, werden in diesem Beitrag die Möglichkeiten diskutiert, wie solche Systeme mit Ressourcen in der Cloud erweiterbar sind. Es wird eine Systemarchitektur und deren Umsetzung vorgestellt, die konstante, wie auch schwankende Bildverarbeitungskapazitäten in der Cloud skalierbar erschließen.

Abstract:
Technologia optyki adaptywnej (AO, adaptive optics) stała się w ostatnim czasie cennym narzędziem diagnostycznym w badaniach nad mikrostrukturą i funkcją siatkówki. Wykorzystując światło z zakresu bliskiej podczerwieni, kamera optyki adaptywnej umożliwia nieinwazyjne obrazowanie fotoreceptorów (głównie czopków), ściany i światła naczyń siatkówki, włókien nerwowych oraz struktur blaszki sitowej, które trudno uwidocznić za pomocą innych, stosowanych obecnie technik. Technologia AO może dostarczyć informacji o patologicznych zmianach w siatkówce, nawet gdy brakuje jakichkolwiek odchyleń od normy w obrazowych badaniach strukturalnych lub funkcjonalnych. Obecnie aparat rtx1TM (Imagine Eyes, Francja) jest jedynym urządzeniem z kamerą optyki adaptywnej dopuszczonym do badań okulistycznych w wielu krajach. W niniejszym artykule przedstawiamy krótki przegląd rozwoju technologii optyki adaptywnej oraz stale zmieniające się możliwości jej zastosowania w diagnostyce okulistycznej.

Abstract:
The topic of this paper is an evaluation of developed sensor intended for navigation aid of unmanned aerial vehicles (UAVs). Its operation is based on processing images acquired with a thermal camera operating in the long-wave infrared band (LWIR) placed underneath a vehicle’s chassis. The vehicle’s spatial displacement is determined by analyzing movement of characteristic thermal radiation points (ground, forest, buildings, etc.) in pictures acquired by the thermal camera. Magnitude and direction of displacement is obtained by processing the stream of consecutive pictures with optical-flow based algorithm in real time. Radiation distribution analysis allows to calculate camera’s self-translation vector. Advantages of measuring translation based on thermal image analysis is lack of drift effect, resistance to magnetic field variations, low susceptibility to electromagnetic interference and change in weather conditions as compared to traditional inertial navigation sensors. As opposed to visible light situational awareness sensors, it offers operation in complete darkness (harsh weather, nights and indoors).The topic of this paper is an evaluation of developed sensor intended for navigation aid of unmanned aerial vehicles (UAVs).

Abstract:
Plat Nomor Kendaraan merupakan identitas bagi setiap kendaraan bermotor yang terdaftar oleh pemerintah Indonesia. Proses identifikasi plat nomor diawali dengan pembambilan gambar kendaraan dengan kamera. Gambar akan di resize untuk menyamakan ukuran citra dan crop untuk memisahkan antara plat nomor dengan bagian kendaraan lainnya menggunakan algoritma Perspective Transform, setelah itu di crop kembali untuk memisahkan antara kode wilayah, kode registrasi dan kode seri wilayah, lalu setiap karakter akan dikenali menggunakan metode Optical Character Recognition (OCR) berdasarkan citra karakter hasil crop. Terdapat proses character error handling untuk meningkatkan tingkat akurasi identifikasi pada karakter plat nomor. Plat nomor Indonesia yang diujikan terbagi menjadi 4 kategori yaitu Plat Standar Mobil, Plat Kustom Mobil, Plat Tidak Standar dan Plat Motor. Resolusi kamera terbaik menggunakan resolusi 1280x720 piksel dan menghasilkan rata-rata waktu uji 6,51 detik. Persentase kebenaran identifikasi karakter terbesar untuk plat standar sebesar 100% pada nilai lux 20~39 dan nilai lux 70~99, sedangkan untuk plat nomor kustom persentase kebenaran identifikasi karakter terbesar sebesar 58% pada nilai lux 90~140. Sedangkan untuk plat tidak standar tidak ada persentase kebenaran identifikasi karakter terbesar menghasilkan persentase 0% pada semua nilai lux yang diujikan. Untuk plat nomor motor persentase kebenaran identifikasi karakter terbesar sebesar 8% pada nilai lux 150~199. Sehingga dapat ditarik kesimpulan bahwa plat nomor standar menjadi rekomendasi yang tepat bagi setiap kendaraan bermotor yang ada di Indonesia.

Abstract:
Keyboard, mouse, dan joystick merupakan perangkat keras yang sering digunakan untuk interaksi antara manusia dan komputer yang bersifat mekanis. Meskipun akurat, tetapi model interaksi yang dilakukan tidak bersifat alami sebagaimana manusia berinteraksi dengan sesamanya. Penggunaan peralatan-peralatan tersebut untuk mengoperasikannya membutuhkan adanya kontak langsung antara user dengan komputer. Dengan menggunakan visi komputer tidak membutuhkan kontak langsung pengguna dengan peralatan input, melainkan komputer menangkap gerakan pengguna melalui kamera video dan menginterpretasikannya. Gerakan yang diteliti disini adalah gerakan tangan. Kamera (webcam) merupakan alat yang digunakan untuk melakukan pengenalan tangan. Kamera ini digunakan sebagai sensor untuk mendeteksi pergerakan tangan. Pendeteksian gerakan tangan diimplementasikan dengan menggunakan library emguCV dan algoritma optical flow. Penerapan dari keakuratan aplikasi yang dibuat adalah dengan memainkan game pingpong. Uji coba menggunakan game pingpong sederhana dimana gerakannya kiri kanan atas bawah. Ketika kursor keatas otomatis bat pingpong keatas, dan seterusnya. Dari ujicoba penelitian dengan pencahayaan terang dimana resolusi webcame yang diuji coba 3 MP dan 1 MP, game pingpong lancar dimainkan sedangkan dengan pencahayaan redup, cursor lambat bergerak otomatis bat pingpong juga ikut lambat.Keyboard, mouse, and joystick are hardware devices that are often used for the interaction between humans and computers being mechanical. Although accurate, but the model of interactions is not naturally as humans interact with each other. The use of such equipment to operate it requires direct contact between user and computer. By using a computer vision does not require direct contact with the user input device, but a motion capture computer user via a video camera and interpreting them. Movements studied here is the movement of the hand. The camera (webcam) is a tool used to perform the introduction of the hand. These cameras are used as sensors to detect hand movements. The detection of hand movements implemented using emguCV library and optical flow algorithm. Implementation of the accuracy of the application is made is by playing Ping-Pong game. Test using a simple ping pong game in which the movement left top right bottom. When the cursor upwards automatically ping pong bat up, and so on. From research trials with bright lighting where webcam tested resolution of 3 MP and 1 MP, a Ping-Pong game played smoothly while the dim lighting, the slow-moving cursor automatically Ping-Pong bat also slow.

Abstract:
Presbyopia remains the last frontier for refractive surgeons. With increased demand for spectacle independence at all ages, ophthalmologists are exploring different approaches for presbyopia correction. The idea of adding synthetic material to the cornea for the management of presbyopia has come a long way since its inception. The Raindrop® (ReVision Optics®), KAMRA™ Inlays (AcuFocus™) and the Flexivue Microlens™ (Presbia™) are three very different inlays that attempt to reverse presbyopia through different mechanisms. The Raindrop changes the curvature of the anterior cornea in the plane of the pupil, the Kamra uses the principle of the pinhole to increase depth of focus, while the Flexivue is a refractive annular add lenticule that creates a paracentral zone for near vision. The decreased incidence of complications, ease of insertion, reversibility and potential applicability to patients with various refractive statuses make inlays a powerful addition to the armamentarium in the management of presbyopia.

Abstract:
This thesis deals with the study of parameters of diaphragm discharge in liquids. NaCl solution of different conductivity was used as a conductive medium. Conductivities were adjusted in the range from 220 to 1000 µS cm-1. Two diagnostic methods were used for the study of plasma parameters. The first one was employed in the laboratory of plasma chemistry at Faculty of Chemistry, Brno University of Technology, namely the optical emission spectroscopy. The second method used for plasma diagnostics was the time resolved ICCD camera at the Laboratoire de Physique des Plasmas at the École Polytechnique in Paris. The reactor for the diagnostics by optical emission spectroscopy had the volume of 4 l, and it was made of polycarbonate. PET diaphragm was placed in the barrier separating the cathode and the anode space. Electrodes were made of titanium coated with platinum. Electric power source supplied a constant DC voltage of maximum 5 kV and electric current up to 300 mA. Spectrometer Jobin Yvon TRIAX 550 with CCD detector was used during the experiments in order to measure overview spectra within the range from 200 to 900 nm as well as OH molecular spectra and Hß line spectra. All spectra were scanned in both discharge polarities, i.e. at the cathode and the anode part of reactor. The basic parameters of the discharge plasma were calculated from the spectra, that means rotational and electron temperature and electron density. Another part of experiment consisted of measurements by the ICCD camera iStar 734. Two types of reactors were used. The first one was the same as the reactor for the measurements by the optical emission spectroscopy. The second one was also made of polycarbonate, but the volume of conductive solution was 110 ml, only. HV electrodes made of stainless steel were placed in this reactor. Ceramic diaphragm (Shapal-MTM) was used in both reactors. Diaphragms had different thickness and diameter of holes. ICCD camera acquired photographs with details of processes of the bubbles generation and discharge operation (propagation of plasma channels), depending on solution conductivity, dimensions of the diaphragm, and with respect to the electrode part of the reactor.

This thesis deals with problematics of PTZ-camera re-calibration during movement. The objective of this work is to keep the camera in calibration mode from default status when the known positions of Vanishing Points are in the image. With their use during movement, which is changing with motion of the camera, their positions are kept with help of two implemented methods. The first method is based on the principle of homography, the second on the principle of cross ratio. The results show that both of these methods work especially for keeping the positions of First Vanishing Points. In the case of the Second Vanishing Points there appear various problems and the results are often quite inaccurate.
