In this study, improved path tracking control algorithm based on pure pursuit algorithm is newly proposed by using improved lane detection algorithm through real time post-processing with interpolation methodology. Since the original pure pursuit works well only at speeds below 20 km/h, the look-ahead distance is implemented as a sigmoid function to work well at an average speed of 45 km/h to improve tracking performance. In addition, a smoothing filter was added to reduce the steering angle vibration of the original algorithm, and the stability of the steering angle was improved. The post-processing algorithm presented has implemented more robust lane recognition system using real-time pre/post processing method with deep learning and estimated interpolation. Real time processing is more cost-effective than the method using lots of computing resources and building abundant datasets for improving the performance of deep learning networks. Therefore, this paper also presents improved lane detection performance by using the final results with naive computer vision codes and pre/post processing. Firstly, the pre-processing was newly designed for real-time processing and robust recognition performance of augmentation. Secondly, the post-processing was designed to detect lanes by receiving the segmentation results based on the estimated interpolation in consideration of the properties of the continuous lanes. Consequently, experimental results by utilizing driving guidance line information from processing parts show that the improved lane detection algorithm is effective to minimize the lateral offset error in the diverse maneuvering roads.

As one of the most important issues in computer vision and image processing, online object tracking plays a key role in numerous areas of research and in many real applications. In this study, we present a novel tracking method based on the proposed structured sparse representation model, in which the tracked object is assumed to be sparsely represented by a set of object and background templates. The contributions of this work are threefold. First, the structure information of all the candidate samples is utilized by a joint sparse representation model, where the representation coefficients of these candidates are promoted to share the same sparse patterns. This representation model can be effectively solved by the simultaneous orthogonal matching pursuit method. In addition, we develop a tracking algorithm based on the proposed representation model, a discriminative candidate selection scheme, and a simple model updating method. Finally, we conduct numerous experiments on several challenging video clips to evaluate the proposed tracker in comparison with various state-of-the-art tracking algorithms. Both qualitative and quantitative evaluations on a number of challenging video clips show that our tracker achieves better performance than the other state-of-the-art methods.

This study was aimed to make clear fashion is an expression art displaying not only functional or commercial aspects, but creative functions as an artistic work by analyzing Art Mode and its values, and to help develop more creative design by combining fashion with art. In terms of method, relevant documents, precedent studies, and the works announced in domestic and foreign fashion collections, such as Vogue, Fashion News, Gap, and Collections from 2000 to 2009. According to the findings, artistic works were used by the Art Mode in modern fashion. The respect of artists was expressed using historic famous painting works or current works in various fields, designers' individuality was shown by directly applying work messages to clothes, and fashion design was converted into a tool to communicate the messages like artistic works. Second, the various styles, using the formative character of modern art styles from animalism to modern abstractism, showed the creativity of design, transformed art into the art that enables to see the image of modern art, and presented the possibility of developing into a newer creative design through the application of numerous art styles and the transformation of ideas. Third, the collaboration with artists was used. Fashion designers or fashion brands tried to change the images of works or brands in partnership with artists or to increase differentiated images. The future direction of fashion is a pursuit of new form and content to express fashion, not simply to use artistic works. It is expected that such pursuit will lead to more creative and artistic fashion design.

The cold image of digital culture and its realistic limits force modern people to yearn for an emotional world characterized by a warm humanity. The kind of digital technology that appeals to such a human emotion is accepted as a new digital concept in the 21st century. The purpose of this study was to examine the characteristics of emotionality, which was a new trend in digital culture, and to discuss its form and meaning in fashion sector. It's basically meant to figure out a major trend in the 21st century's digital culture, to delve into its relationship with fashion reflecting sociocultural phenomena, and ultimately to describe in which direction future fashion would be led. Emotionality was highlighted as a reaction against an absolute pursuit of speed and cold digital technology. Emotionality of digital culture in fashion design were inserting of funology, Zen-based design and development of a clothing mixture. The emphasis of emotionality in digital culture is a new sociocultural trend that stresses the recovery of human nature. As futurologists predict that a human-centered and humanistic culture will reappear in the 21st century, fashion also will be in pursuit of human-oriented design.
