Patent number: 8649629Abstract: An image enhancement method and system are provided. The image enhancement method and system are capable of improving image quality by performing gamma corrections on global and local illuminations and reflectance estimated from an input image, in consideration of dynamic range and contrast of the image, respectively. Particularly, in a case of a color image, the red, green, and blue (RGB) component images are converted into hue, saturation, and value (HSV) component images, and the global and local illuminations and reflectance estimated from the V component image. By converting the hue (H), saturation (S), and enhanced value (V) into RGB, an enhanced color image can be obtained.Type: GrantFiled: September 19, 2007Date of Patent: February 11, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Chae Whan Lim, Jong In Kwak, Ick Hoon Jang, Doo Hyun Choi, Nam Chul Kim

Publication number: 20080051653Abstract: Embodiments of the present invention may provide an image processing system and method for calculating the volume of a specific portion in a targeted body. According to an embodiment of the present invention, an image processing system may comprise a volume data receiver, a user interface, a display and a main processor. The volume data receiver may form volume data of a target object based on image data thereof. The user interface may receive reference section information on a reference section of the target object, slice section information on a plurality of slice sections each being perpendicular to the reference section and contour information from a user. The display may form an image of the reference section and images of the slice sections based on the volume data. The main processor may set a reference sectional object and slice sectional objects based on the reference section information and the slice section information, respectively.Type: ApplicationFiled: August 13, 2007Publication date: February 28, 2008Applicant: Medison Co., Ltd.Inventors: Doo Hyun CHOI, Eui Chul Kwon, Sung Yun Kim
