EM specimens often contain 3-dimensional information that is lost during micrography on a single photographic film. Two images of one specimen at appropriate orientations give a stereo view, but complex structures composed of multiple objects of graded density that superimpose in each projection are often difficult to decipher in stereo. Several analytical methods for 3-D reconstruction from multiple images of a serially tilted specimen are available, but they are all time-consuming and computationally intense.

Operational Modes

The HB5 STEM instrument at ASU has been modified previously to include an efficient two-dimensional detector incorporating an optical analyser device and also a digital system for the recording of multiple images. The detector system was built to explore a wide range of possibilities including in-line electron holography, the observation and recording of diffraction patterns from very small specimen regions (having diameters as small as 3Å) and the formation of both bright field and dark field images by detection of various portions of the diffraction pattern. Experience in the use of this system has shown that sane of its capabilities are unique and valuable. For other purposes it appears that, while the principles of the operational modes may be verified, the practical applications are limited by the details of the initial design.

Standard Practices

Dear readers,The year 2017 marks the 55th anniversary of the Journal of Information & Communications of the Ministry of Information and Communications, and the 18th anniversary of its scientific publication – the Research and Development on Information and Communication Technology (RD-ICT) journal. Again, the purpose of RD-ICT is to provide a forum for researchers and professionals to disseminate original and innovative ideas in the fields of information technology, communications and electronics in Vietnam and worldwide.Without kind support and invaluable contribution of readers and authors, and hard work of the anonymous reviewers and editors under the former editorship of Prof. Nguyễn Thúc Hải, Prof. Trần Văn Lộc and Prof. Nguyễn Cảnh Tuấn, RD-ICT would not be what it is today – a total of 37 issues in Vietnamese and 14 issues in English.To contribute to the development of research in Vietnam, toward standard practices, high quality and international visibility, RD-ICT has been taking measures by following current practices of prestigious international research journals. In this editorial, we would like to inform you some of the things we have been doing lately.Since June 2014, RD-ICT has applied online journal management and publishing, thanks to the well-known open-source Open Journal System of the Public Knowledge Project, which is used by thousands of online scientific journals worldwide. The editorial board of RD-ICT is currently being extended to include international prominent scientists, thus forming a team of international associate editors, under the complementary technical editorship of Prof. Đỗ Ngọc Minh (University of Illinois at Urbana-Champaign, United States), Prof. Nguyễn Hoàng Hà (University of Saskatchewan, Canada) and Prof. Nguyễn Linh Trung (Vietnam National University, Hanoi). Each submission is now assigned to an associate editor who then coordinates the review process and makes editorial decision.For improved paper quality in terms of organization and presentation, authors are guided to good practice of technical paper writing. In addition, accepted submissions are now copy-edited, by the corresponding associate editors, and laid out using LATEX.Apart from already being an open-access journal, RD-ICT is also looking into other measures to increase its visibility, such as all-English publishing, digital object identification, Google Scholar citation, and SCOPUS indexing.Taking the opportunity of informing the above changes, we would like to, again, express our sincere gratitude and appreciation to the readers, authors, reviewers and editors of RD-ICT, and to the leadership of the Ministry of Information and Communications and its predecessors – the Directorate General of Posts and Telecommunications, the Ministry of Post and Telecommunications – for their continued support and contribution to RD-ICT.We look forward to your comments and feedback for better developing the RD-ICT journal for Vietnam.Sincerely,Vũ Chí Kiên, Editor-in-ChiefĐỗ Ngọc Minh, Nguyễn Hoàng Hà, Nguyễn Linh Trung, Technical Editors-in-Chief

Detecting objects in a video stream is a typical problem in modern computer vision systems that are used in multiple areas. Object detection can be done on both static images and on frames of a video stream. Essentially, object detection means finding color and intensity non-uniformities which can be treated as physical objects. Beside that, the operations of finding coordinates, size and other characteristics of these non-uniformities that can be used to solve other computer vision related problems like object identification can be executed. In this paper, we study three algorithms which can be used to detect objects of different nature and are based on different approaches: detection of color non-uniformities, frame difference and feature detection. As the input data, we use a video stream which is obtained from a video camera or from an mp4 video file. Simulations and testing of the algoritms were done on a universal computer based on an open-source hardware, built on the Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC processor with frequency 1,5GHz. The software was created in Visual Studio 2019 using OpenCV 4 on Windows 10 and on a universal computer operated under Linux (Raspbian Buster OS) for an open-source hardware. In the paper, the methods under consideration are compared. The results of the paper can be used in research and development of modern computer vision systems used for different purposes.

The Media

AbstrakImaji visual fotografi merupakan media rekam visual yang objektif dan representatifkebenarannya dalam merekam suatu realitas. Revolusi teknologi menyebabkan perubahandari teknologi fotografi analog sebagai salah satu media yang menyatakan kebenaran ataubukti dan sebagai media yang representatif kebenarannya ke teknologi digital yang dapatmemungkinkan untuk merekayasa gambar digital melalui perangkat lunak. Teknologi digitaltelah menjadikan kebenaran dalam sebuah foto tidak lagi absolut. Akhirnya fotografi sebagaialat perekam imaji yang representatif kebenarannya semakin diragukan. Karena semakin sulituntuk membedakan foto asli atau palsu, bahkan sebuah foto asli bisa saja dikatakan sebagaihasil manipulasi. Penciptaan imajinasi visual fotografi ini dihasilkan dari suatu olah daya pikirmanusia. Dalam proses tersebut dibutuhkan suatu kreativitas dari penggabungan imaji-imajisebelumnya atau sekarang ini untuk diimajinasikan. Pemaknaan akan bergeser dari imaji visualfotografi menjadi imaji visual fotografi yang baru. Proses artistik imajinasi visual ini diciptakandengan didasarkan pada artistik yang berdasarkan imajinasi, artistik berdasarkan imajinasi danartistik didasarkan pada kombinasi antara kenyataan dan imajinasi. Penciptaan Imajinasi visualfotografi merupakan daya untuk mengonstruksi ataau menggabungkan kembali dari berbagaiimaji-imaji atau foto- secara imajinatif dan kreatif dengan persepsi yang menyertainya untukmenjadi imaji baru yang utuh, logis, dan mungkin terjadi dengan menggunakan teknik danefek fotografi. Proses mengonstruksi membutuhkan suatu kemampuan berimajinasi untukmenggabungkan dan menyatukannya untuk menjadi satu kesatuan (unity) yang utuh dalam satupermukaan gambar/imaji secara ekspresif dan imajinatif melalui proses estetis yang kreatifberdasarkan ciri personal penciptanya. Dengan demikian, hasil dari proses konstruksi tersebutsudah tidak tampak lagi imaji sebelumnya dan pemaknaannya sudah bergeser menjadi karyaimaji dengan pemaknaan baru.AbstractImage to Photography Visual Imagination. Visual image of photography is a visual recordingmedia which is objective and representative in revealing the truth when recording a reality. Thetechnology revolution led to the change in photography, from analog photographic technologyas one of the media for promoting truth or evidence and as media representing truth to thedigital technology which allow people to manipulate digital images through software. Digitaltechnology has made the truth in a photograph is no longer absolute. In the end, photographyas an images recording tool representing truth is doubted. It is getting harder and moredifficult to distinguish the original or fake photo, even an original photo can be said as aresult of manipulation.The creation of visual imagination photography is produced by thepower of human thought. The process requires a creativity of merging the previous or recentimages to imagine. The meanings will be shifted from visual image photography into a newvisual image photography. Visual imagination of the artistic process is created on the basisof artistic imagination, artistic imagination and artistic are based on a combination of realityand imagination.The creation of visual photography imagination is a power to construct orrecombine from multiple images or pictures imaginatively and creatively with the perceptionto be a whole new image, logical, and may occur with the use of techniques and photographiceffects. The process of constructing requires an ability of imagining to combine and unitethem into a single unit as a unity which is intact on s single surface of the picture/image,expressively and imaginatively through an aesthetic creative process based on the personalcharacteristics of the creator. By doing so, the construction process will no longer visible onthe former image and the meaning will shift into an image with a new meaning.
