摘要:
An image processing apparatus is provided. A splitting unit of the image processing apparatus may split a first space within an input three-dimensional (3D) model into a plurality of subspaces in order to generate an acceleration structure of the input 3D model. A decision unit of the image processing apparatus may set a subspace determined as having a relatively high probability of including a ray progress path among the plurality of subspaces, as a child node having a relatively high traversal priority in the acceleration structure among a plurality of child nodes.

An image rendering apparatus may include a buffer memory unit and a processor. The buffer memory unit may store input ray data for image rendering according to a ray tracing scheme while shape data corresponding to the input ray data is being fetched from a cache. The processor may output the received shape data together with the input ray data to an operation apparatus.

A photographing method, medium, and apparatus based on face detection in a portable camera. The portable photographing apparatus may include an image input unit that receives an image, a face detection unit that detects a face from the received image, a storage unit that stores the image detected by the face detection unit as a moving image in a first mode, and a quality evaluation unit that evaluates the quality of the image detected by the face detection unit and stores the same as a still image in a second mode upon satisfaction of predetermined conditions evaluated based on the quality evaluation of the still image.

An exercise unit for applying a rectilinear vibration and a swing vibration to the user. The exercise unit is divided into a lateral vibration part and a swing vibration part which are driven by two separated driving motor respectively. The lateral vibration part converts a rotative motion of the motor into a rectilinear vibrating motion to provide the user with the rectilinear vibration. The swing vibration part converts the rotative motion into a swing vibrating motion to provide the user with the swing vibration. The two parts may be selectively driven by a single driving motor.

A method and apparatus for detecting multi-view faces. The method of detecting multi-view face, includes the operations of (a) sequentially attempting to detect from an input image two mode faces among a first mode face made by up and down rotation, a second mode face made by leaning a head to the left and right, and a third mode face made by left and right rotation; (b) attempting to detect the remaining mode face that is not detected in operation (a); and (c) determining that a face is detected from the input image when the remaining mode face is detected in operation (b), wherein operation (b) comprises (b-1) arranging face detectors for all directions in parallel, when face detection succeeds in one direction, performing face detection in the same direction using a more complex face detector, and when face detection fails in one direction, performing face detection in a different direction; and (b-2) independently and separately arranging the face detectors for all directions, when face detection succeeds in one direction, performing face detection in the same direction using a more complex face detector, and when face detection fails, determining that a face is not detected from the input image.
摘要:
Disclosed is a method of producing a polyethylene terephthalate-based polyester fiber, including spinning polyethylene terephthalate based polyester to produce an undrawn yarn with an intrinsic viscosity of 0.83 or more and a density of 1.338 g/cm3 or more, multi-stage drawing the undrawn yarn, heat-setting the drawn yarn, relaxing the heat-set yarn, and winding the relaxed yarn to produce the resulting drawn yarn with an intrinsic viscosity of 0.83 or more and a density of 1.38 to 1.3865 g/cm3. Compared to a prior polyester yarn with high modulus and low shrinkage, produced according to conventional melt-spinning and drawing processes, an industrial polyester yarn with high modulus and low shrinkage according to the present invention contributes to significantly improving strength retention (tenacity of a dip cord/tenacity of a grey yarn) of the dip cord, produced by treating the polyester yarn of the present invention with an adhesive (RFL) and subsequently heat-treating the RFL-treated polyester yarn. Therefore, the polyester multifilament yarn according to the present invention is useful as a tire cord.
