Abstract
A similar shader search apparatus using image feature extraction includes: an image extraction unit configured to classify color, texture, pattern features of a 2D image, into a color feature set, a texture feature set, and a pattern feature set, numerically analyze the respective feature sets, and extract a feature value of the image; a shader extraction unit configured to analyze a predetermined stored shader, classify features having an effect upon color, texture, and pattern into a color feature set, a texture feature set, and a pattern feature set, numerically analyze the respective feature sets, and extract a feature value of the shader; and a distance function calculation unit configured to receive the image feature value and the shader feature value, calculate the similarity of color between the image and the shader, and calculate the similarity of texture between the image and the shader using the Euclidean distance function.
