AbstractThis paper proposes an aesthetic-driven evolutionary algorithm for user-centered design. The evolutionary algorithm is based on a genetic algorithm (GA). It is developed to work as an art form generator that enhances user's productivity and creativity through reproduction, evaluation, and selection. Users can input their preferences and guide the generating direction to the system. A two-step fitness function is developed to evaluate morphology and aesthetics of the generated art forms. Fractals created by an iterated function system are used for representing art forms in our process. Algorithmic aesthetics are developed based on the aesthetic measure theory, surveys of human preferences, and popular long-lasting symbols. The algorithmic aesthetics is used for evaluating aesthetics of art forms together with subjective nonquantifiable aspects, and placed in the fitness function. The GA basically creates two-dimensional art forms. However, any two-dimensional image can be included through the property of a condensation set of fractals. The proposed GA can increase design productivity by about 80%. Examples of jewelry designs and physical prototypes created by the proposed system are included.

A two-dimensional image matching method based on the improved Hausdorff distance and global harmony search optimization is presented in this paper. First, edges are extracted form the original images by the Canny edge detector. Then, a fitness function based on the improved Hausdorff distance is constructed. Finally the global harmony search optimization is adopted to optimize the fitness function. Experiments show that the proposed method is able to locate the object of interest globally and efficiently.

Why care about painting as an art? Does it offer to engage our aesthetic interest in ways that other art forms do not, or does it merely reproduce the aesthetic satisfactions they provide? Most paintings involve both marks on a surface, and something represented by those marks. Some attempts to say what is distinctive about painting concentrate on the former feature, understanding the art as an exploration of the two-dimensional picture plane. Others concentrate on the representational aspect, seeking to find something special about the things painting can represent, or the way in which it achieves this. The most promising approaches acknowledge both aspects, and do so as essential elements in the experiencewe have of painting. One such approach turns on the idea that the configurational aspect ‘inflects’ the representational, so that what we see in the picture itself somehow involves the marks from which the painting is composed. Another sees painting as offering aesthetic values found elsewhere, but in a distinctive form. Taking seriously the idea of our experience of painting also helps us to say something about a set of paintings we are otherwise in danger of ignoring - abstract works.

Business Placement Center membantu mengelola website alumni dalam memenuhi kebutuhan alumni salah satunya memberikan informasi mengenai lowongan pekerjaan. Website Alumni Amikom sudah memberikan informasi mengenai lowongan pekerjaan. Namun website alumni masih perlu ditambahkan fitur-fitur menu penunjang dalam mempermudah pencarian informasi pekerjaan yang sesuai keinginan pengguna. Penggunaan metode User Centered Design untuk mempermudah pengguna dalam menggunakan fasilitas yang ada pada website ketika mencari informasi lowongan pekerjaan dan pengguna berperan penting dalam setiap proses UCD. Dengan pendekatan User Centered Design diharapkan dapat menghasilkan tampilan dan fungsionalitas yang maksimal pada rancangan sistem yang dibangun sehingga sesuai dengan kebutuhan pengguna. Metode penelitian yang dilakukan yaitu observasi, wawancara dan kuesioner untuk mengetahui kebutuhan pengguna. Analisis dan perancangan menggunakan pendekatan User Centered Design dan implementasi perancangan sistem. Hasil penelitiannya adalah pengguna merasa nyaman dengan tampilan antarmuka website yang sudah dibangun, informasi yang disajikan mudah dipahami dan fitur-fitur menu sudah berhasil berjalansesuai fungsi.Business Placement Center help manage the website for the needs of alumnus one of them is to provide information on a vacancy. The alumnus website’s provides information about job vacancy. The website still need the support to facilitate the searching all the features the work in accordance with what the use. The method of user centered design to make it easy for users in the use of the existing facilities at the website while searching for information a vacancy and users play an important role in any proses UCD. User Centered Design approach is expected to produce the interface and functionality maximal built in the system so that in accordance with the need of users. Research methodology was by observation, interviews and quesionnaires to find out the need of users. Analysis and design using UCD approach and implementation of the system. The results of research is users feel comfortable with a display interface of website which have been built, the information is easily understood and menu features has been successfully run a function.

Digital imagery is a two-dimensional image process through a digital computer that is used to manipulate and modify images in various ways. Photos are examples of two-dimensional images that can be processed easily. Each photo in the form of a digital image can be processed through a specific software. In the water environment, the light factor greatly influences the results of the quality of the image obtained. With the deepening of underwater shooting, the results obtained will be the darker the quality of the underwater image. . uneven lighting and bluish tones. One of the factors that influence the recognition results in pattern recognition is the quality of the image that is inputted. The image acquired from the source does not always have good quality. The process of repairing digital images that experience interference in lighting. The lighting repair process uses homomorphic filtering and uses contrast striching and will compare the quality of both methods and test to prove the results of image quality between homomorphic filtering and contrast streching. Until later the results of both methods can be seen which is better. homomorphic filtering and contrast stretching can produce image improvements with pretty good performance.Keywords: Digital Image, Underwater Image, Homomorphic Filtering, Contrast Streching, Matlab R2010a

Digital imagery is a two-dimensional image process through a digital computer that is used to manipulate and modify images in various ways. Photos are examples of two-dimensional images that can be processed easily. Each photo in the form of a digital image can be processed through certain software devices. In the water environment, light factors greatly influence the results of image quality obtained. With the deepening of underwater shooting, the results obtained will be the darker the quality of the underwater image. Underwater imagery is widely used as an object in various activities such as underwater habitat mapping, underwater environment monitoring, underwater object search. Uneven lighting and colors that tend to be bluish and runny. One of the factors that influence the recognition results in pattern recognition is the quality of the image that is inputted. The image acquired from the source does not always have good quality. The process of improvement in digital images that experience interference in lighting and exposure to sunlight. The lighting repair process uses the retinex method and will compare the quality of the two methods later. Until later the results of both methods can be seen which is better. Retinex method can produce image improvement with high performance.Keywords: Digital Cintra, Underwater, Matlab Retinex Method
