Abstract:
An image processing apparatus is provided. The image processing apparatus includes a light capturing unit to generate light environment information by photographing a light environment of an object, and an object capturing unit to generate object information by photographing the object. The image processing apparatus may further include a modeling unit to generate a 3-dimensional (3D) model by reflecting the light environment information and the object information, and a rendering unit to render a resultant image with respect to at least one view using the 3D model.
Abstract:
Provided is an apparatus and method to create a model of a target organ of a patient. The apparatus and method generate a deformation matrix between at least two shape models of a target organ based on at least two three-dimensional (3D) images of the target organ. The apparatus and method also extract constraints about the target organ from a two-dimensional (2D) image of the target organ. The apparatus and method create the model of the target organ based on the constraints and the deformation matrix.
Abstract:
An image processing apparatus is provided. When a depth image is input, an outlier removing unit of the image processing apparatus may analyze depth values of the whole pixels, remove pixels deviating from an average value by at least a predetermined value, and thereby process the pixels as a hole. The input depth image may be regenerated by filling the hole. During the above process, hole filling may be performed using a pull-push scheme.
Abstract:
An apparatus and method for encoding a 3D mesh, and an apparatus and method for decoding the 3D mesh are disclosed. The 3D mesh encoding apparatus may determine mesh information including position information of each of vertices constituting the 3D mesh, and connectivity information among the vertices, based on a level, and may progressively encode the determined mesh information based on the level, thereby reducing an error with an original 3D object when compared to an equal transmission rating.

Abstract:
A plane detection apparatus for detecting at least one plane model from an input depth image. The plane detection apparatus may include an image divider to divide the input depth image into a plurality of patches, a plane model estimator to calculate one or more plane models with respect to the plurality of patches including a first patch and a second patch, and a patch merger to iteratively merge patches having a plane model a similarity greater than or equal to a first threshold by comparing plane models of the plurality of patches. When a patch having the plane model similarity greater than or equal to the first threshold is absent, the plane detection apparatus may determine at least one final plane model with respect to the input depth image using previously merged patches.
Abstract:
An image processing apparatus may include a light capturing unit to generate light environment information by photographing or capturing a light environment of an object, and an object capturing unit to generate object information by photographing or capturing the object. The image processing apparatus may further include a modeling unit to generate a 3-dimensional (3D) model by reflecting or combining the light environment information and the object information, and a rendering unit to render a resultant image with respect to at least one view using the 3D model.
