This paper is aimed at embodying the optimal system for foreign workforce supply of nation in order to introduce qualified foreign workers at the age of eleven thousand foreigners. It is difficult to employ foreign workers qualified and it makes job rosters' confidence fall down which is the supplementary resources when selecting due to the insufficient job seekers' detailed information. Therefore, the moving control system should be added in current system to deal with these problems. For this, in this paper, we propose that the moving picture embedded system applies to the current EPS utilizing multimedia, network and database technologies as regards adding the function of the moving picture synthesis to recent system. It also suggests the advanced foreign employment control system related to the advanced system which makes employers to hire foreign workers satisfying their requirements and demand.

Recently, there are various studies underway on the deep learning-used image matting methods. Even in the field of photogrammetry, a process of extracting information about relics from images photographed is essential to produce a high-quality realistic model. Such a process requires a great deal of time and manpower, so chroma-key has been used for extraction so far. This method is low in accuracy of sub-classification, however, it is difficult to apply the existing method to high-quality realistic models. Thus, this study attempted to remove background information from high-resolution relic images by using prior background information and trained learning data and evaluate both qualitative and quantitative results of the relic images extracted. As a result, this proposed method with FBA(manual trimap) showed quantitatively better results, and even in the qualitative evaluation, it was high in accuracy of classification around relics. Accordingly, this study confirmed the applicability of the proposed method in the indoor relic photography since it showed high accuracy and fast processing speed by acquiring prior background information when classifying high-resolution relic images.
