The present invention provides a diaminopyrimidine derivative or its pharmaceutically acceptable salt, a process for the preparation thereof, a pharmaceutical composition comprising the same, and a use thereof. The diaminopyrimidine derivative or its pharmaceutically acceptable salt functions as a 5-HTreceptor agonist, and therefore can be usefully applied for preventing or treating dysfunction in gastrointestinal motility, one of the gastrointestinal diseases, such as gastroesophageal reflux disease (GERD), constipation, irritable bowel syndrome (IBS), dyspepsia, post-operative ileus, delayed gastric emptying, gastroparesis, intestinal pseudo-obstruction, drug-induced delayed transit, or diabetic gastric atony.

Diaminopyrimidine derivatives and processes for the preparation thereof

A method and apparatus for matching images are provided. The image matching method includes: obtaining a depth image and an intensity image of an object using a depth camera installed at a first position and a color image of the object using a color camera installed at a second position other than the first position; transforming the obtained depth image and intensity image into a depth image and an intensity image, respectively, that could be obtained if the object were photographed by a camera at the second position; and matching the transformed depth image and intensity image and the obtained color image. In this way, a depth image and intensity image obtained separately from a 2-dimensional (2D) color image can be accurately matched to the 2D color image, thereby allowing a reliable 3D image to be obtained.

Method and apparatus for matching color image and depth image

A method, medium, and apparatus processing depth information of a depth image. The apparatus adaptively presenting information on depth information includes a section determination unit determining which one of plural sections respective depth values for pixels of the 3D image fall within, with the plural sections being defined by a measured limit distance for the 3D image being parsed into the plural sections based on distance based depth resolution information, and an adaptive quantization unit to selectively quantize and represent each depth value based on a respective predefined quantization setting of the one section.

Method, medium, and apparatus representing adaptive information of 3D depth image

Provided is a rendering apparatus and method. After a rendering image is generated by forming a splat for each of points generated by projecting a model composed of a plurality of points, then a plurality of predetermined regions which extend over a boundary of the generated rendering image are selected for each splat forming the boundary of the rendering image, and a pixel value of each pixel included in each of the selected regions is corrected based on pixel values of the pixel and its surrounding pixels, thereby correcting the boundary of the rendering image to make the boundary appear to be more natural and thus improving the display quality of the rendering image.

Rendering apparatus and method

Provided is a method and apparatus for inpainting a depth image and a color image seen from one viewpoint by using a depth image and a color image inpainted from another viewpoint. The method includes detecting an edge on the basis of a difference between depth values of pixels in a first image seen from a view viewpoint and inpainting depth values of pixels in an occlusion region that is shown in a second image seen from a second viewpoint but not shown in the first image, in a direction from pixels in a region having high depth values among regions forming the edge to pixels in a region having low depth values.

Image inpainting method and apparatus based on viewpoint change

A method and apparatus for obtaining depth information are provided. The method includes calculating a relative depth value between a first color pixel and a second color pixel based on values of color pixels of a color image, and calculating a depth value of a second depth pixel that belongs to a depth image corresponding to the color image, matches the second color pixel, and does not have the depth value, based on the calculated relative depth value and a depth value of a first depth value that belongs to the depth image, matching the first color pixel, and has the depth value thereof.
