Abstract: A hardware apparatus and a method for creating an integral image are disclosed. The hardware apparatus calculating a feature point and descriptor of an image, includes: an image fading unit which reduces the maximum bit number into a predefined bit number by fading an entire inputted black and white image; an integral image creating unit which sequentially calculates pixel values of the black and white image outputted from the image fading unit to buffer, as an offset, a pixel value accumulated up to a previous line, and stores, as a differential value, a pixel value accumulated from a first pixel of a following line; and a first integral value acquisition unit which calculates a pixel value of a first integral image required to extract the feature point using the offset and the differential value.

Abstract: PURPOSE: A similarity measurement method and a recording medium thereof are provided to improve accuracy of correspondence by searching a correspondence point of the correspondence image through detection and matching of a feature amount. CONSTITUTION: A computer readable code searches multiple correspondence points among correspondence images(S110). The code forms multiple correspondence blocks including the correspondence points among the correspondence images. The code produces first similarity by comparing color distribution of the correspondence blocks(S120). The code forms an image overlapped area among the entire area of the correspondence image. The code produces second similarity by comparing color distribution of the image overlapped areas(S130). The code measures similarity of the correspondence image by granting a weighting factor to the first and the second similarity(S140). [Reference numerals] (AA) Start; (BB) End; (S110) Searching a correspondence point between correspondence images; (S120) Generating a correspondence block and calculating a first similarity; (S130) Generating an overlapped area and calculating a second similarity; (S140) Measuring similarity of the correspondence image by granting a weighting factor to the first and the second similarities
