摘要:
A method for coding three-dimensional (3D) data, and more particularly for coding geometry data included in the 3D data. The method includes: generating a bounding box including a vertex of the 3D data based on information included in the geometry data; dividing the bounding box into a plurality of partitions having an equal size; identifying a number of vertices included in each divided partition; appointing a divided partition as a leaf cell based on the identified number of vertices; and coding the geometry data using information on the dividing of the bounding box, information on vertices included in each divided partition, and information indicating the position of a vertex included in the leaf cell, when a divided partition is subdivided.
摘要:
A method for photographing a panoramic picture, and for identifying motion of a photographing apparatus to automatically photograph respective images of a panoramic picture. The method steps include: (a) obtaining a first image in response to a request for a panoramic picture photography; (b) identifying motion of a photographing apparatus having obtained the first image, by applying a motion estimation technique to currently input images; (c) automatically determining a photographing direction based on the identified motion of the photographing apparatus; (d) selectively applying a motion estimation technique for estimating motion in a horizontal direction or a vertical direction, according to the determined photographing direction, and identifying motion of the photographing apparatus; (e) judging photographing time points of respective images by identifying that the identified motion of the photographing apparatus has reached a preset threshold value for decision of the photographing time point; and (f) photographing images at the photographing time point of the respective images.

摘要:
A panoramic picture photographing method permits more accurate photographing of an image, particularly a panoramic image of a subject, without additional equipment, or separate devices and hardware. The method includes projecting an image, which is successively inputted in every predetermined unit of time, to an imaginary surface having a same focal distance in photographing each image constituting a panoramic picture to obtain a projected image; confirming movement of a corresponding photographing apparatus so that the projected image is compared with a previous image in real time by using a motion estimation technique, to which exposure correction has been applied; determining a photographing time point of each image by confirming the confirmed movement of the corresponding photographing apparatus according to a photographing direction has reached a predetermined critical value; and photographing each image at the photographing time point of each image according to a passive input or automatically.

摘要:
Disclosed is a method for evaluating the qualities of the user's color vision by means of the FM chromaticity test or directly measuring the defective factors of the user causing the color blindness. Thus it modifies the color composition of a video displaying apparatus according to a numerical analysis of the color and degree of color blindness specific to each dichromatic individual, so that he may perceive the same colors as the normal person. Also discloses is an apparatus for performing the method steps described herein.
摘要:
An apparatus and method for performing color conversion using a color cache is disclosed. The apparatus includes a color converter for acquiring an after conversion color by performing a color conversion operation of a color of a predetermined pixel, a color cache for storing before conversion colors and after conversion colors of previous pixels color-converted by the color converter and searching for the same color by comparing the color of the predetermined pixel to the stored colors before conversion when the predetermined pixel is input, and a controller for transmitting the color of the predetermined pixel to the color cache, controlling the color cache to search whether the same color as that of the predetermined pixel is stored in the color cache, acquiring a after conversion color from the color converter or the color cache according to the search result, and transmitting the color after conversion to the outside.
