Region-based Super-Resolution Aided Facial Feature Extraction from Low-resolution Video Sequences
No full textFacial feature extraction is a fundamental problem in image processing. Correct extraction of features is essential for the success of many applications. Typical feature extraction algorithms fail for low resolution images which do not contain sufficient facial detail. In this paper, a region-based super-resolution aided facial feature extraction method for low resolution video sequences is described. The region based approach makes use of segmented faces as the region of interest whereby a significant reduction in computational burden of the super-resolution algorithm is achieved. The results indicate that the region-based super-resolution aided extraction algorithm provides significant performance improvement in terms of correct detection in accurately locating the facial feature points

In this paper, a region-based super-resolution aided facial feature extraction method for low resolution video sequences is described.

The results indicate that the region-based super-resolution aided facial feature extraction algorithm provides significant performance improvement in terms of correctly detecting the location of the facial feature points. There are 6.4 fold reductions in the computational cost
Puisi: Ramadan merintis celik kewangan / Mustafa Kamal Mat
No full textPuisi ini mengangkat tema Ramadan sebagai masa muhasabah diri dan memperbaiki amalan, khususnya dalam aspek pengurusan kewangan. Ia menekankan pentingnya menjauhi sikap boros, merancang belanjawan dengan bijak, serta mencatat setiap aliran kewangan untuk mencapai kestabilan dan kebebasan kewangan. Pendidikan kewangan turut ditekankan sebagai asas penting dalam membina kehidupan yang terancang dan positif, di mana kefahaman terhadap risiko dan keutamaan simpanan mampu mengurangkan beban masalah kewangan
Selectivity for dimers in pentene oligomerization over acid zeolites
No full textThe reactions of 1-pentene over acid zeolites were investigated in the liquid phase at 473 K. The primary reactions were isomerization, dimerization, and subsequent cracking of dimers. Zeolites consisting of only 10-membered (MFI) or 12-membered rings (FAU, BEA) behaved similarly, with dimerization and subsequent cracking products observed. Zeolites possessing 8-membered ring pores (MOR, FER) showed very different selectivity from each other and from other zeolites. MOR showed almost complete conversion of C10 olefins, such that hexene and butene from cracking were the dominant products. FER showed high activity and selectivity for dimerization, with very small amounts of cracking products observed.Peer reviewe
How Does Macroeconomic and Socio-Political Index Affect the Real Gdp Per Qualified Worker? Evidence From Turkic Republics
No full textCelik, Esref Ugur/0000-0001-9090-9346; Erdal, Fehmi Buğra/0000-0002-9485-5290; Kucuker, Mustafa Can/0000-0002-1504-0270; Omay, Tolga/0000-0003-0263-2258In this study, we concentrated on the socioeconomic factors affecting the level of real GDP per qualified worker. For this purpose, we have used the macroeconomic and socio-political performance index for Turkic Republics. By using these newly established indices, determinants of the level of real GDP per qualified worker are analyzed for the first time in the literature. From the empirical investigation, we found that certain threshold levels significantly affect the real GDP level per qualified worker. Therefore, the policymakers of these countries should seriously consider these threshold levels for macroeconomic and socio-political performance index for conducting a well-organized policy for the prosperity of their countries
Book review: French-language road cinema: borders, diasporas, migration and 'New Europe' by Michael Gott
No full textAs road movies have become more prominent in European cinema, in French-Language Road Cinema: Borders, Diasporas, Migration and ‘New Europe’ author Michael Gott analyses a corpus of French-language films that utilise the road to explore the complexity of mobility, borders and identity in contemporary Europe. Ipek Celik Rappas welcomes this as a thoughtful, timely and exciting book that will be an indispensable guide for researchers in European film and mobility studies
Comparative content, biological and anticancer activities of Heracleum humile extracts obtained by ultrasound-assisted extraction method
No full textAs the safety and effectiveness of synthetic drugs remain in doubt, researchers are trying to develop natural medicines from medicinal plants. Herein, ethyl acetate, methanol and water extracts from the Heracleum humile plant were obtained by an ultrasonic-assisted extraction process and the aim was to evaluate some biological effects of the extracts due to the limited data on the pharmacological properties of Heracleum humile in the literature. Weak antibacterial activity was observed on tested bacterial species. The minimum inhibitory concentration and the minimum bactericidal concentration values ranged from 250 to 500 μg/mL. In addition, cytotoxic activity was determined using the MTT test. The strongest findings were determined for ethyl acetate extract on the MDA-MB-231 cell line at the 48th hour (IC50:97.94 μg/mL), followed by the MCF-7 cell line at the 24th hour (IC50:103.9 μg/mL). All extracts of Heracleum humile contained mainly flavonoids, phenolic acids and their derivatives, i.e., well-known compounds that possess numerous biological activities such as antioxidant, anti-inflammatory, anticancer, antimicrobial etc. The study results could provide important information that Heracleum humile could be a potential candidate as a natural enzyme inhibitor. It can be concluded that these extracts could be useful in the elementary step of improving novel plant-derived multifunctional pharmaceuticals
Device and method for processing a digital video
No full textThe present invention provides a device for processing a digital video, wherein the device comprises a video analyzing unit configured to segment multimedia data of an input digital video to audial data and a plurality of video segments, and determine a video content information for each video segment by analyzing the audial data and frames of the video segment; a determination unit configured to detect at least one surface in a video segment, and select an advertisement image from a database for the detected surface, based on a semantic similarity between meta-data of the advertisement image and the determined video content information of the corresponding video segment; and a processing unit configured to generate an output video, by embedding the selected advertisement image from the database on the detected surface
