A method for recognizing a music score included in an image and various information included in the music score, which may be obtained through a camera provided in a mobile terminal without requiring a separate editing program. The method includes detecting a region with staff lines from the image including the music score; detecting a region with an accompaniment chord from the image by taking the region with the staff lines and a region with a musical note into consideration; extracting and removing the staff lines from the music score included in the image; recognizing the musical note by extracting the musical note from the image, from which the staff lines have been removed; recognizing the accompaniment chord by extracting the accompaniment chord from the image, from which the staff lines have been removed; and generating data for reproducing a sound source corresponding to the musical note and accompaniment chord.

A method for photographing a panoramic picture includes the steps of checking motion of a corresponding photographing apparatus compares currently input images and previous images in real time through a motion estimation technique employing exposure compensation. Respective images constituting a panoramic picture are photographed, and image photography information is checked that includes focus distance and optical magnification to calculate actual photography range distance of the images. A pre-set threshold is set in consideration of a calculated actual photography range distance of the images. The checked motion is confirmed as to whether the pre-set threshold has been reached, and photography time points of the respective images are determined. The respective images are photographed according to a manual mode or an automatic mode at the photography time point of the respective images.

A method for photographing a panoramic picture, and for identifying motion of a photographing apparatus to automatically photograph respective images of a panoramic picture. The method steps include: (a) obtaining a first image in response to a request for a panoramic picture photography; (b) identifying motion of a photographing apparatus having obtained the first image, by applying a motion estimation technique to currently input images; (c) automatically determining a photographing direction based on the identified motion of the photographing apparatus; (d) selectively applying a motion estimation technique for estimating motion in a horizontal direction or a vertical direction, according to the determined photographing direction, and identifying motion of the photographing apparatus; (e) judging photographing time points of respective images by identifying that the identified motion of the photographing apparatus has reached a preset threshold value for decision of the photographing time point; and (f) photographing images at the photographing time point of the respective images.

An apparatus and method for simplifying 3-Dimensional (3D) mesh data are disclosed. The method includes measuring discrete curvature at each point of received 3D mesh data, calculating an error based on distance-curvature error metrics including the discrete curvature, first sorting a low curvature one of the calculated error values in a heap in ascending order, selecting a minimum error among the calculated errors, determining if the minimum error is less than a threshold, contracting an edge if the selected minimum error is greater than the threshold, and recalculating an error of a surface neighboring to a surface on which the contracted edge belongs and re-sorting the calculated error values.

Disclosed is a method of extracting ridge and valley lines from three-dimensional point data, the method including the steps of: receiving undefined point data obtained from a three-dimensional scanning system; estimating a normal vector by principal component analysis so as to calculate a normal vector with regard to each received point; and on the basis of such information, creating a moving least squares (MLS) surface of points approximation with regard to each received point. Then, Delaunay edge is created by a Voronoi diagram with regard to each point from the created MLS surface of points; and ridge (or valley) points are extracted by measuring zero-crossing on each Delaunay edge. Ridges and valleys as lines are created by connecting the extracted ridge points in a principal curvature direction. The extraction of ridge and valley lines is used as a pre-processing step for creating three-dimensional points into mesh data, and is advantageous for identifying general model features.

A panoramic picture photographing method permits more accurate photographing of an image, particularly a panoramic image of a subject, without additional equipment, or separate devices and hardware. The method includes projecting an image, which is successively inputted in every predetermined unit of time, to an imaginary surface having a same focal distance in photographing each image constituting a panoramic picture to obtain a projected image; confirming movement of a corresponding photographing apparatus so that the projected image is compared with a previous image in real time by using a motion estimation technique, to which exposure correction has been applied; determining a photographing time point of each image by confirming the confirmed movement of the corresponding photographing apparatus according to a photographing direction has reached a predetermined critical value; and photographing each image at the photographing time point of each image according to a passive input or automatically.
