This study intended to analyze the transition of design of Korean soccer player's uniform according to development of the society and changes in formative elements, and examine features inside them by considering designs of soccer player's uniform by ages ranging from the introduction of soccer up to now. Results of the study are summed up below. First, as a result of analyzing designs of soccer player's uniforms from 1920 to 2002 Korea-Japan WorldCup based on formative elements of the style of dress. \circled1 it is shown that basic shape has been kept but changes in only color. cutting, trimming, logo and symbol have existed. \circled2 Colors of the uniforms have been different according to ages but red, blue and white colors have been used most and sometimes black was employed. so it is known that colors in the Korean national emblem have been all used. \circled3 In the beginning of the uniform there was a limitation in its design due to absence of functional materials but now highly-sensitive textile products and highly-functional textile materials guaranteeing optimal condition and highest activity of a soccer player have been utilized in various ways. \circled4 It is known that symbols modelling the image of Korea have been used in diverse ways but effected much by directions toward images pursued by designers of sponsors. Second, the meanings represented by designs of the uniforms are classified into a degree of symbolizing Korea, tradition, superiority and dynamics. That is to say, \circled1as colors and symbols coming from the emblem have been used in the uniforms. they have symbolized one nation and possessed the meaning representing even Korean national spirit. \circled2As traditional colouring and symbols have been used in the uniforms, they have shown the Korean sense of a beauty. \circled3 Colors, tones and designs overwhelming the mood of play have been used in the uniforms, so that they have played a role in making players of other team flinch mentally and making Korean players gain an advantage over them. \circled4 Thanks to strong symbols or comparative effects of colors. they have shown the dynamics representing power and energy.

In this paper, we develop an algorithm of soccer image sequences mosaicing using reverse affine transform. The continuous mosaic images of soccer ground field allows the user/viewer to view a “wide picture” of the player’s actions The first step of our algorithm is to automatic detection and tracking player, ball and some lines such as center circle, sideline, penalty line and so on. For this purpose, we use the ground field extraction algorithm using color information and player and line detection algorithm using four P-rules and two L-rules. The second step is Affine transform to map the points from image to model coordinate using predefined and pre-detected four points. General Affine transformation has many holes in target image. In order to delete these holes, we use reverse Affine transform. We tested our method in real image sequence and the experimental results are given.

To create a more realistic soccer game derived from TV images, we are developing an image synthesis system that generates 3D image sequence from TV images. We propose the method for the team and the pose recognition of players in TV images. The representation includes camera calibration method, team recognition method and pose recognition method. To find the location of a player on the field, a field model is constructed and a player's field position is transformed by 4-feature points. To recognize the team information of players, we compute RGB mean values and standard deviations of a player in TV images. Finally, to recognize pose of a player, this system computes the velocity and the ratio of player(height/width). Experimental results are included to evaluate the performance of the team and the pose recognition.
