Problems solved by technology

According to this method, the user has to manually adjust the direction and gain of the illumination during the conversion to the 3D image, and as a result, there has been a problem that the converted 3D image does not exhibit the characteristics of a true 2D image
Therefore, in the case of moving images (moving picture), it is necessary to manually adjust the lighting direction and gain for each image, and the above-mentioned graphics tools do not have functions such as blurring and noise prevention
Therefore, it is difficult and impractical to represent three-dimensional moving images with such typical methods

Abstract

A 3-dimensional image is generated from an input 2-dimensional image based upon illuminative characteristics of the input image by filtering the 2-dimensional input image with filters of different orientations, outputting base shading images corresponding to the filters, extracting positive pixel values for each base shading image, calculating a difference between the pixel values of the input image and the extracted positive pixel values, calculating a median value of the calculated difference, selecting the filter to output a base shading image of smallest median, outputting a shading image by filtering the input image with the selected filter, combining the input image with the shading image and outputting the 3-dimensional image based upon the combined image. A previously selected filter for a preceding image can be considered when selecting a filter for a current image, enabling generation of 3-dimensional moving pictures.

Description

technical field [0001] The present invention generally relates to an apparatus for generating a three-dimensional image from a two-dimensional image and a method thereof, and more particularly, the present invention relates to an apparatus for generating a three-dimensional image by adding shade to an outline region of an input two-dimensional image and a method thereof . Background technique [0002] Photoshop, marketed by Adobe Systems and widely used around the world, employs a method of filtering images in RGB or CIE-Lab format to convert a two-dimensional image into a three-dimensional image. According to this method, a user must manually adjust the direction and gain of illumination during conversion to a three-dimensional image, and as a result, there has been a problem that the characteristics of a true two-dimensional image are not represented in the converted three-dimensional image. In addition, although an image can be expressed in a three-dimensional image afte...
