Abstract:
An SAD calculation method and apparatus for estimating variable block movement are provided to detect a moving vector with regard to a size of a variable block and process operations of SAD effectively and rapidly in parallel. A PE array unit(401) simultaneously calculates an SAD value of at least one pixel. At least one PE(Processing Element) is arranged in at least one pixel in a matrix form. And a matrix in at least one pixel is included in continuous current frame macro blocks. A local memory, current frame macro block data, reference frame macro block data and reference frame search area data are included. The local memory transmits data to each PE included in a PE array unit.

Abstract:
An image registration device according to an embodiment of the present invention comprises: a first feature vector magnitude calculating unit for calculating a magnitude of feature vectors corresponding to at least first feature point among feature points of a reference image, and generating a first magnitude value; a second feature vector magnitude calculating unit for calculating a magnitude of feature vectors corresponding to at least second feature point among feature points of a target image, and generating a second magnitude value; a magnitude difference calculating unit for receiving the first and second magnitude values, calculating a magnitude difference between the received first and second magnitude values, and generating a third magnitude value; a first threshold value generating unit for generating a first threshold value based on the first magnitude value and a magnitude ratio set from the outside; and a magnitude difference determining unit for receiving the third magnitude value and the first threshold value, and determining a magnitude difference between the received third magnitude value and the received first threshold value. When it is determined by the magnitude difference determining unit that the third magnitude value is less than the first threshold value, a similarity calculation of the first and second feature points is performed. When it is determined that the third magnitude value is greater than the first threshold value, a magnitude of another feature point of the target image and a magnitude of the first feature point are compared.
