Abstract: A portable terminal and a method for editing an image are provided, which make the image that a user wants displayed on the portable terminal. A method for editing an image is as follows. If the image processed as the mosaic image is selected, the selected image is divided into the block image(330). The divided block image color mean value is produced. It determines whether the high position mosaic image for producing the mosaic image is selected or not. In the selected high position mosaic image, the mosaic image corresponding to the calculated color mean value is searched(350). The block image is replaced with the searched mosaic image and the mosaic image is indicated(355,360).

Abstract: A feature-preserving simplification method of 3D(three-dimensional) mesh data is provided to simplify a complicated 3D mesh model to a user desired level, and reduce time and costs by reducing a manual operation of a designer in a 3D geometry model. 3D mesh data is received from a 3D range scanning system(S100). An approximated surface is generated for points of 3D mesh data by using MLS(Moving Least Squares) approximation technique(S110). Curvatures and curvature differentiation values for each point on the surface are calculated(S120). A ridge point is searched by measuring zero-crossing of a curvature differentiation at a Delaunay edge, namely, neighbor information obtained by connecting each point(S130). Zero-crossing is measured by using a third-order or fourth-order differentiation value to extract feature points(S140). A ridge point is randomly selected and connected to a nearby ridge point, which is repeatedly performed to generate a ridge line(S150). An unnecessary feature line is removed from the ridge lines, namely, from feature lines(S160). An edge and a quadric error metric are calculated with respect to the feature lines and feature-preserved(S170,S180).

Abstract: A high-speed image processing method based on a graphics accelerator and an apparatus thereof are provided to assign an input texture and an output texture equally in at least one FBO to use an output result as input data without an additional process, thereby shortening a process time and reducing the usage of a memory. A pixel shader(30) of a GPU(Graphic Processing Unit) receives and processes texture data(302) of 32-bit floating-point data, and has at least one FBO(Frame Buffer Object)(333). An input image, an image processing target, is loaded to a video memory as the texture data. The pixel shader performs a specific algorithm for image processing for the input image, and outputs a result to at least one FBO as the texture data. An application performs rectangular rendering matching the entire screen and performs the binding of the contents of the FBOs to a texture. Finally, the image processing result performed by the pixel shader is rendered to a viewport. Floating-point data generated in image processing is represented by assigning the type of input and output textures to the type of a 32-bit real number.
