Digital image matting is the process of softly fetching foreground objects from an image. It has become a widely used application for editing the images and to give special effect in the film production industry. Reducing the cost in film making, giving special effect in movies and editing the images are the main motivations for matting. This paper provides a concise review of various approaches for solving matting problem. These approaches can be broadly categorized into two categories: Trimap-based and Scribble-based matting approaches. This paper also provides strengths and weaknesses of various approaches coming under these categories. Finally, the paper concludes with the comparative analysis of all approaches reviewed under both the categories.

The main characteristics of graphic information compression methods with losses and without losses (RLE, LZW, Huffman's method, DEFLATE, JBIG, JPEG, JPEG 2000, Lossless JPEG, fractal and Wawelet) are analyzed in the article. Effective transmission and storage of images in railway communication systems is an important task now. Because large images require large storage resources. This task has become very important in recent years, as the problems of information transmission by telecommunication channels of the transport infrastructure have become urgent. There is also a great need for video conferencing, where the task is to effectively compress video data - because the greater the amount of data, the greater the cost of transmitting information, respectively. Therefore, the use of image compression methods that reduce the file size is the solution to this task. The study highlights the advantages and disadvantages of compression methods. The comparative analysis the basic possibilities of compression methods of graphic information is carried out. The relevance lies in the efficient transfer and storage of graphical information, as big data requires large resources for storage. The practical significance lies in solving the problem of effectively reducing the data size by applying known compression methods.

Rachmawati AK, Anandito RBK, Manuhara GJ. 2010. Extraction and characterization of pectin on green cincau (Premna oblongifolia) in edible film production. Biofarmasi 8: 1-10. The use of green cincau pectin was presumed to influence the result of edible film characteristics, i.e. thickness, solvability, elongation, tensile strength, and water vapour transmission (WVTR). The aims in this research were: (i) to find out the chemical characteristics of green cincau pectin on the physical (thickness and solvability) and mechanical properties (elongation and tensile strength), (ii) to determine the edible film inhibition of green cincau pectin against the water vapour transmission rate, and (iii) to find out the edible film capability in inhibiting the weight loss on green grape by wrapping and coating method. The five major steps in this research were material preparation (making green cincau powder and pectin extraction), the characterization of extraction result pectin, making edible film, edible film characterization, and edible film application. This research used a completely randomized design with twice replications in edible film making for each treatment concentration and twice replication for edible film characteristic testing in each edible film making replication. Variance analysis was used to analyze data, if there was a significant difference, it will be continued with a Duncan Multiple Range Test at a significance level of 0.05. The yield of green cincau powder and pectin were 27.5% and 15.2%, respectively. The extraction result pectin consisted of 5.09% water, 11.06% protein, 0.35% fat, 28.5% ash, 55.00% carbohydrate (by different), and 12.15% crude fiber. The increasing of pectin concentration tends to increase the thickness and tensile strength, but reduced the water vapour transmission rate. The lowest water vapour transmission rate occurred at the edible film with 30% pectin concentration. Its water vapour transmission rate was 0.317 g.mm/m2.hour. The green grape weight loss with a wrapping method was 0.0212 g/hour, and the green grape weight loss with a coating method was 0.0634 g/hour.

Academic research pertaining to the marketing of film industry has identified advertising, film-making, and star power as the important factors influencing a movie’s market performance. Prior research, however, has not investigated the joint influences of these factors. The current study has extended previous research by analyzing the investment decision of studios or investors. In order to analyze the optimal film investment decision in advertising, film-making, and stars power, this paper develops a goodwill model and system dynamic (SD) model, which allow us to disentangle the effects of advertising, film-making, and star power on film market performance. The results show that the film producer should increasingly lay emphasis on investing in advertising to absorb moviegoers’ attention. Then the film producer should focus on investing in film-making when film quality has a great impact on the movie's reputation and audience's viewing decision. Furthermore, the film producer should pay more attention to the higher cost-performance stars who have more reasonable remuneration, better acting skills, and bigger box-office guarantee. Moreover, the numerical analysis reveals that rational audience contribute more than fans to a movie's box-office and bankable stars contribute more than high-profile stars to a movie's returns. Through SD simulation analysis, the film series yields higher profits than new theme movies although the cost of investment is the same.

The aim of this study is to realize an analysis of public-private partnerships (PPPs) in Albania. Our focus will mainly be the PPPs in the energy sector. Public-private partnerships contracts have experienced a significant increase in the last decades in Albania. They have had a great impact on public finances of the country, this is why they have often been “attacked” for the negative impact that they might have on the actual and especially the future of the country. We will work to make a comparative analysis of the cost and benefits that Albania has had from signing these contracts. We will also work to analyze the management of these public-private partnerships during the pandemics, which will be helpful to reveal the possible difficulties that the government might have in managing them. Something that has inspired us to make a deeper analysis of them is related to the energy crises that the country has experienced in the last years. We want to “dig” deeper in order to see if these PPPs are really worth it or not. Is it worth or it brings a burden for the actual and future generations of Albania?

Today, agricultural sector develops in many areas. So, we have decided to make a project that can bring facileness by using the developing technology. We aimed to harvest the olives easily to work in these agricultural areas with a mechanical machine. We knew that there are many olive trees in our country and that people spend a lot of time collecting olives in these trees and they work costly. Therefore, we decided to design a machine that would also protect the environment by reducing the cost that would lead to saving. We met with many people and companies who went to the machine production industry and made studies in this field. Based on this information, we have decided to make a mechanism that works with shaking tree branch thanks to the gear system. As a result of our work, we think that this mechanism will be operated in a healthy manner and ready for production. The mechanism requires 159.2 N.m of torque, 1620 N force and 1 ~1.7 kW of manpower.

What was the potential for the development of a Scottish film industry? Current histories largely ignore the contribution of Scotland to British film production, focusing on a few amateur attempts at narrative film-making. In this chapter, Caroline Merz offers a richer and more complex view of Scotland’s incursion into film production,. Using a case-study approach, it details a production history of Rob Roy, produced by a Scottish company, United Films, in 1911, indicating the experience on which it drew, placing it in the context of other successful British feature films such as Beerbohm’s Henry VIII, and noting both its success in Australia and New Zealand and its relative failure on the home market faced with competition from other English-language production companies.
