Apparatus and method for similar shader search using image feature extraction

PURPOSE: A similar shader search device using image feature extraction and a method thereof are provided to detect more easily and quickly a shader which is similar to a desired image by establishing similarity measure through the image feature extraction and drawing a distance function between the image and the shader based on the similarity measure. CONSTITUTION: An image extractor(100) classifies a color, a texture and a pattern feature into a color, texture and pattern feature set, and numerically analyzes the set, and extracts a characteristic value of an image. A shader extractor(104) extracts a characteristic value of shaders which are predetermined and saved. A distance function calculation unit(110) receives an image feature value and a shader feature value, and calculates the similarity of the color sense between the image and the shader based on a vector based distance function, and calculates the similarity of the texture based on a Euclidian distance function.
