Pemodelan Wajah 3D Melalui Pendeteksian Fitur Wajah 2D Menggunakan Teknik Morphing<br>3D MODELS OF FACIAL FEATURES WITH THE DETECTION OF 2D FACES USING MORPHING TECHNIQUES

ABSTRAKSI: Face recognition atau pengenalan wajah adalah salah satu teknologi biometrik yang telah banyak diaplikasikan dalam sistem security selain pengenalan retina mata, pengenalan sidik jari dan iris mata. Dalam aplikasinya sendiri pengenalan wajah menggunakan sebuah kamera untuk menangkap wajah seseorang kemudian dibandingkan dengan wajah yang sebelumnya telah disimpan di dalam database tertentu. Pada saat ini penggunaan grafika komputer memiliki peranan yang besar terutama pada grafik 3D. Yang dimaksud obyek 3D adalah setiap titik yang membentuk obyek akan diproses memiliki 3 sumbu koordinat. Pada tugas akhir ini telah dibuat model wajah 3D melalui pembacaan model yang dihasilkan oleh software stlread, kemudian dilakukan pemilihan vertex dan face untuk membentuk model baru (wajah). Setelah itu pendeteksian lokasi fitur wajah dilakukan dengan menyesuaikan letak titik – titik fitur wajah terhadap wajah input, kemudian melakukan proses sampling warna dan pembacaan hasil sampling warna sehingga diperoleh model 3D yang sesuai input. Dalam tugas akhir ini, telah dilakukan survey MOS terhadap 30 responden dengan dua kategori yaitu pergeseran dan penskalaan terhadap dua sumbu koordinat yaitu x dan y serta ukuran dimensi yang berbeda -beda dari lima jenis citra input. Citra input pria dan wanita yang masing – masing mewakili dua citra untuk pria dan tiga citra untuk wanita. Hasil MOS menunjukkan nilai rata – rata kualitas pemodelan yang dihasilkan untuk ukuran dimensi 400 x 400 pixel adalah baik dan 233 x 368 pixel bernilai cukup dengan tingkat akurasi berdasarkan hasil MOS dari 30 responden adalah 82.1% untuk 400 x 400 pixel dan 63.5% untuk 233 x 368 pixel.Kata Kunci : objek 2D, objek 3D, sampling warna, vertex, faceABSTRACT: Face recognition is a biometric technology which have a lot of application in system security besides of retina, fingerprint recognition and slice eye. In the application of face recognition use a camera to catch a face and then compared to face previously have been kept in certain database. Today, a grafika computer using a big role especially 3D graph. 3D object is a dot forming obyek will be processed to own 3 axis of coordinates. this final project have been made a face 3D models by software stlread,and then election vertex and face to forming a new models. Afterwards the location fitur face detection accomodatedly is arrest point - dot fitur face to input face, then do a read and colour sampling process that obtained of 3D models. In this final project have been done by MOS to 30 responder with two category that is scale and friction to two axis of coordinates that is x and y and also the size measure different dimension to type the different input. woman and man Input image which deputize two image for the man and three image for the woman. With result of dimension 400 x 400 pixel is good and 233 x 368 pixel is enough. . Result MOS from 30 responder is 82.1% to 400 x 400 pixel and 63.5% to 233 x 368 pixel.Keyword: 2D Object, 3D Object, color sampling, vertex, fac

Preparation and Characterization of Chitosan/Reduced Graphene Oxide Film as a Sensing Material

Sensing materials are crucial in a wide range of fields, including environmental monitoring, healthcare, security, and industrial applications. By leveraging their specific properties, sensing materials enable the development of innovative sensing devices and systems for improved detection, monitoring, and control of various parameters in our environment. This study aimed to prepare the chitosan/reduced graphene oxide film as sensing materials using a simple casting method. The reduced graphene oxide (rGO) was mixed with chitosan (CS), consisting of a concentration ratio of 200, 250, 300, 350, and 400 ppm. Three characterizations were used to describe the formed CS/rGO films, namely, Fourier transform infrared (FTIR), X-ray diffraction (XRD), and cyclic voltammetry (CV). FTIR and XRD analysis results were successfully performed, which showed that the process of loading of rGO and the film fabrication occurred in the physical interaction. The CV test also showed that the CS/rGO modified electrode has high sensitivity in PBH pH 7 and can be applied as a sensing material

Postharvest Quality of Kiwifruit (Actinidia chinensis) after X-ray Irradiation Quarantine Treatment

The quality of two kiwifruit varieties [Actinidia chinensis var. deliciosa, ‘Hayward’ (green-fleshed), and Actinidia chinensis var. chinensis, ‘Zesy002’ (gold-fleshed)] was determined after X-ray irradiation at doses suitable for disinfestation of quarantine pests. Fruit were treated with irradiation doses of 0, 200, 400, 600, or 800 Gy and stored for 14 days at 2 °C. Irradiation did not affect soluble solids content, respiration rate, or taste. Minimal softening occurred to ‘Zesy002’ treated with irradiation doses of 400 or 800 Gy. No visible radiation injury, scald, or discoloration was observed. Irradiation treatment of kiwifruit at doses ≤800 Gy would ensure visual, compositional, and sensory quality while providing quarantine security

Breaking a chaos-based secure communication scheme designed by an improved modulation method

Recently Bu and Wang [Chaos, Solitons & Fractals 19 (2004) 919] proposed a simple modulation method aiming to improve the security of chaos-based secure communications against return-map-based attacks. Soon this modulation method was independently cryptanalyzed by Chee et al. [Chaos, Solitons & Fractals 21 (2004) 1129], Wu et al. [Chaos, Solitons & Fractals 22 (2004) 367], and \'{A}lvarez et al. [Chaos, Solitons & Fractals, accepted (2004), arXiv:nlin.CD/0406065] via different attacks. As an enhancement to the Bu-Wang method, an improving scheme was suggested by Wu et al. by removing the relationship between the modulating function and the zero-points. The present paper points out that the improved scheme proposed by Wu et al. is still insecure against a new attack. Compared with the existing attacks, the proposed attack is more powerful and can also break the original Bu-Wang scheme. Furthermore, it is pointed out that the security of the modulation-based schemes is not so satisfactory from a pure cryptographical point of view. The synchronization performance of this class of modulation-based schemes is also discussed.Comment: elsart.cls, 18 pages, 9 figure

Memory-Based High-Level Synthesis Optimizations Security Exploration on the Power Side-Channel

High-level synthesis (HLS) allows hardware designers to think algorithmically and not worry about low-level, cycle-by-cycle details. This provides the ability to quickly explore the architectural design space and tradeoffs between resource utilization and performance. Unfortunately, security evaluation is not a standard part of the HLS design flow. In this article, we aim to understand the effects of memory-based HLS optimizations on power side-channel leakage. We use Xilinx Vivado HLS to develop different cryptographic cores, implement them on a Spartan-6 FPGA, and collect power traces. We evaluate the designs with respect to resource utilization, performance, and information leakage through power consumption. We have two important observations and contributions. First, the choice of resource optimization directive results in different levels of side-channel vulnerabilities. Second, the partitioning optimization directive can greatly compromise the hardware cryptographic system through power side-channel leakage due to the deployment of memory control logic. We describe an evaluation procedure for power side-channel leakage and use it to make best-effort recommendations about how to design more secure architectures in the cryptographic domain
