Provided are a method for extracting a correlation to generate 3D motion data, and a motion capture system and method using the extracting method to easily compose a humanoid character on a real background image. Cameras for motion capture are installed in a real background capture location (such as an outdoor location or in a studio), and the correlation between motion capture fixed cameras and a moving camera for capturing a real background image is obtained to capture 3D motion data prior to performing motion capture for integrating a humanoid character, so that even when there is interaction between a 3D figure and an actual prop such as a chair or table within the captured space, a humanoid character can easily be composed with the real background.

A method of extracting line segments from a subject image includes calculating a gradient image and a direction image of respective edge pixels in a canny edge image obtained from the subject image, calculating a primary line passing arbitrary two pixels selected among the edge pixels, selecting candidate line segment pixels through performing an incremental pixel extension from a midpoint of the two pixels forming the primary line, and extracting the line segments by checking whether the candidate line segment pixels are connected to each another.

Provided is an apparatus and method for detecting a horizon which is necessary to detect a camera movement when compositing sea images in a marker-free sea-image camera tracking system. In the method, an ROI is selected near a horizon in a still image of the moving image of the sea, and each maximum point corresponding to the maximum brightness difference is detected from brightness differences between two pixels of each pair having two symmetrical pixels in each column of the ROI. The horizon is detected through a line-fitting using the maximum points. Therefore, the result of horizon detection can be very stable and a horizon can be easily detected in a sea scene having hundreds of frames.

Provided is a method of manufacturing a thin film magnetic head. In particular, a method of manufacturing a thin film magnetic head is provided in which a flow process of a photoresist is applied to separate a hard magnetic layer and a metal multi-layer and a photoresist is used to insulate an upper electrode from a lower electrode in manufacturing a magnetic reproduction device, thereby simplifying and optimizing a manufacturing process and significantly reducing a manufacturing time.
